About PowerWatch

About PowerWatch

Thank you for choosing another world-class Event Logger from ACR Systems

Inc. The PowerWatch Voltage Disturbance Recorder (

VDR

) is an easy-touse, low-cost power quality analysis tool that troubleshoots power line disturbances.

The PowerWatch VDR

PowerWatch VDR Features

The PowerWatch VDR records surges, sags, impulses, outages and frequency variations. It is self powered and easy to use - parameters can be set by a few easy keystrokes from your PC.

The VDR can retain 4,000 events. The existence of recorded events can be indicated by the VDR's flashing light.

Communication between a PC and the VDR is carried via the Lite-Link interface cable. By using this optical data transfer, the PC remains electrically isolated.

Safety Precautions

The VDR is designed and certified to work only on single-phase systems.

Attempting to modify the VDR or operating it improperly may cause circuit damage which can ultimately result in property damage, personal injury, or death.

Plugging in a PowerWatch VDR

The VDR is designed to plug into a standard convenience outlet. As a safety precaution, the unit should be in a place where it can be easily unplugged.

This will also make it accessible for data retrieval. The VDR does not use a protective earth connection since there are no exposed metal parts. The earth conductor is used to measure neutral to ground (N-G) events. The ground prong may be electrically unconnected (as long as it is not exposed). The

2007 ACR Systems Inc.

The PowerWatch Voltage Disturbance Recorder

VDR does not normally need any special ventilation, however, its ambient temperature should not be allowed to rise above the operating limit.

6

Electrical Immunity

The VDR's internal circuitry is solid-state with built-in EMI and RFI protection to ensure reliable readings.

Safety Inspection

We recommend that you inspect the VDR periodically for visible damage. To ensure that it operates safely, inspect for missing labels, cracks in the case, or bent blades and/or broken leads.

Battery Care

The VDR contains a lithium battery that will, under normal circumstances, allow the VDR to operate for 10 years. Exposing the VDR to extreme temperatures for extended periods of time may reduce battery life by as much as 50%. The VDR is designed for INDOOR USE. It should not be exposed to direct sunlight.

To extend battery life, keep the VDR plugged into a standard convenience outlet (even when not in use).

WARNING: BATTERY POSES FIRE, EXPLOSION AND SEVERE BURN

HAZARD. DO NOT RECHARGE, DISASSEMBLE, HEAT ABOVE 100°C

(212°F), INCINERATE, OR EXPOSE CONTENTS TO WATER

Maintenance

The PowerWatch VDR is a maintenance-free product. However, it is recommended that it be kept clean to allow for easy visual inspections. To clean the VDR, unplug it from the outlet and wipe it with a dry, clean cloth.

Product Service

The PowerWatch VDR has no user-serviceable parts inside. The fuse inside the VDR is NOT OPERATOR-REPLACEABLE. Opening the case, or attempting to do so, will void the warranty and safety certification. If you require service, please contact your local dealer or factory representative.

Quick Summary

Quick Summary

Quick Summary displays the number of surge, sag, impulse, and frequency events as bars on a graph. Outages are included with sags.

The horizontal axis displays time; the vertical axis displays the number of events that occurred in each time period. In the Quick Summary above, the time periods are sorted by date.

Note that the thickness of a bar and its position in a time period is irrelevant; the bar only displays the number of events and the time period they occurred in.

If more detailed analysis is needed, it may be better to export

the file to a spreadsheet or database for further manipulation.

A Quick Summary can be saved in either a bitmap(BMP) or metafile(WMF) format. In most cases, a metafile format is preferred since it is smaller, is easily scaled, and prints better. However, some applications (such as MS-

PAINT) can only handle the BMP format.

PowerWatch©

A single impulse event between hot and neutral or neutral and ground can be displayed as a graph, enabling you to see if the impulse is causing zero crossings.

An impulse graph is produced using the amplitude, polarity/direction, and position (in degrees) of the event. The graphical representation is not intended to show the actual wave form nor does it show the duration of the impulse.

Important To graph an impulse you must choose an event that contains only

one impulse; it is not possible to graph an event consisting of multiple

impulses

The Event Distribution Graph plots the magnitude of the event against duration on a logarithmic scale in order to determine the importance of the data. For example, a single random event may not be as significant as a cluster of recurring events.

This information can be interpreted using the CBEMA Curve found in

Appendix B, Power Quality Issues, in the PowerWatch Reference Guide.

Since the impulses

have a duration that is unknown, they are represented as having a width of 10 microseconds.

When PowerWatch is run, it first attempts to find all available COM ports and list them on the Communicate menu. Ports that it cannot find either don't exist or are in use. For example, if your computer has two COM ports (1, 2) and if

COM 1 is being used by the mouse, and COM 2 is unused, then only COM 2 will appear on the Communicate menu.

Clicking on an unchecked port will cause PowerWatch to try to open that port; it will also close the currently open port. Clicking on a checked (open) port will close that port. Only one port may be open at a given instant.

Default Threshold Settings

The PowerWatch program has factory-installed default threshold settings.

These settings are adequate for most applications.

Since there is a 110V VDR

and a 220V VDR, two default threshold templates are provided. Connecting with a VDR will automatically use the appropriate one.

To see the default threshold settings on the Status tab, click the Default

Settings button.

If you are concerned that some of your electronic equipment may have particular power quality requirements, we suggest that you call the equipment manufacturer for that information. You may discover that you should alter some of the VDR's threshold settings in order to monitor power quality closer.

The Events column displays the number sequence of each event, with the most recent events displayed first. By using the scroll bar on the right of the window, all the events that the VDR has recorded can be viewed. The number

0 is given to an

Open Event .

Start Time Column

The Start Time column displays the time that an event started. The resolution of the time stamp in a VDR is eight seconds. Therefore, if an impulse occurred

once every second starting at 12:00:00, the first eight impulses

would all be reported to have the same time of 12:00:00. The next eight impulses would be reported as having the same time of 12:00:08. Also, if identical information was downloaded twice from a VDR, the two site reports could show a time difference of eight seconds.

Event Column

The Event column displays the types of events that occurred during the reporting period.

Impulse Events An

Impulse Event

is a transient voltage surge. The event column will display the number of impulses that the VDR was able to count.

For instance, in the Event tab displayed above, event #8 is one impulse; event

#18 is made up of nine impulses.

Surge and Sag Events Surge and sag events are increases and decreases in line voltage that are outside the thresholds for at least one full cycle. Surges

can occur on the hot-neutral lines or on the neutral-ground lines. Sags are only measured on the hot-neutral lines.

Outage Events An

Outage Event

is a 0 voltage sag (for example, event #16 listed above).

High and Low Frequency Events Frequency events are recorded when the frequency is outside the preset frequency thresholds.

Loss of Synchronization Excessive harmonics or noise on a power line may cause severly distorted voltage waveforms. While not common, these distorted waveforms could result in "extra" zero crossings on the AC line.

PowerWatch synchronizes itself to the consecutive positive and negative zero crossings of the AC line (every 8.33 milliseconds). Should the voltage waveform be so highly distorted that unexpected zero crossings are detected,

PowerWatch will report a loss of synchronization relative to the measured voltage waveform.

Extreme Column

The Extreme column displays the maximum value measured during the event.

End Time/Duration/Degree Column

This column displays the duration of an event, or the time that the event ended, or, in the case of a single impulse, the event's position on the sine wave (in degrees).

Information is displayed according to the length of the event.

·

Events of less than one second are displayed in number of cycles.

·

Events of one to 119 seconds are displayed in seconds. Outages up to 16 seconds are recorded in 0.5 cycle resolution, otherwise the outage resolution is eight seconds.

·

Events of between two minutes and 24 hours are displayed in hours, minutes and seconds for example, 07:51:24 (7 hours, 51 minutes, and 24 seconds).

·

Events that last longer than 24 hours display the end time (date and time).

If an event was still in progress when data was downloaded from the VDR, the event will be designated as an open event in this column. PowerWatch can display one each of three open event types simultaneously. Open events are assigned the number zero in the Event # column.

Impulses

Impulses

Impulses are transient voltage fluctuations (sometimes called spikes). They can be positive or negative and can occur on the hot-neutral line or on the neutral-ground line. Impulses typically have a duration far below one cycle time and can be detected below microsecond.

PowerWatch will record any voltage deviation above the impulse limit and of less than one cycle duration as an impulse event.

5.2.1.3

Impulse events

Impulse Events

Impulses are transient voltage fluctuations (sometimes called spikes), can be positive or negative, and can occur on both the hot-neutral line and the neutral-ground line. The voltage potential of an impulse can be quite large; hundreds of volts is not uncommon. Impulses typically have a duration far below one cycle time and can be detected below a microsecond. PowerWatch will record any voltage deviation above the impulse threshold of less than one cycle duration as an impulse.

PowerWatch can detect both positive and negative impulses

down to one microsecond in duration on both the H-N and N-G lines. If the voltage exceeds the impulse deviation threshold within one half cycle, an impulse event will be recorded. An impulse event can include one or more impulses occurring within the same half cycle. The event column will display the number of impulses that the PowerWatch was able to count.

An important point to note about a multiple impulse event is that the voltage reading in the Extreme column will be the total voltage of any impulses that occur more than 100 microseconds apart. When multiple impulses of different polarity occur, their absolute values are added together. The degree (in the fourth column) will be the position in the cycle of the first impulse. The angle of neutral-ground impulses is referenced to the start of the hot-neutral sine wave.

If an impulse is less than one microsecond in length, PowerWatch will measure the magnitude of the impulse but may be unable to determine the polarity. In this case, PowerWatch will show the sign of the impulse as "+"

(firmware version 4 or greater).

Sag Events

Sags are decreases in line voltage lasting for at least one cycle. Sags are only measured on the hot-neutral lines. Typically, a sag will range from a few volts to tens of volts below normal.

If the voltage drops below the sag threshold, a sag event will be recorded. If it drops below 70V, the event will be recorded by PowerWatch as an outage.

Outage events

Outage Events

When PowerWatch records a sag of below 70Vrms for longer than a second it displays the event as an outage. The VDR will go into self-powered mode

(battery) and will sample the voltage every eight seconds. As a result, the shortest outage it will record will be eight seconds. When the power is reapplied to PowerWatch, the VDR will not detect it immediately, but will wait until the next eight-second sample before returning to the line powered operational mode. This delay will prevent contact bounce being reported as an event when PowerWatch is plugged into a standard electrical outlet.

Since PowerWatch's eight-second clock is not synchronized with outages, it can sometimes report an outage as 16 seconds when in fact the outage only lasted for slightly over one second. An example of when this would happen is if a sag below 70Vrms occurred 6.9 seconds into an eight-second period. At the 7.9-second point, PowerWatch would change to self powered mode and report a minimum outage of eight seconds. If then, at the 8.1-second point, power was restored, the VDR would not sample again until the 16-second point.

Frequency events are variations in frequency above or below the nominal frequency (for example, 60Hz in North America and 50Hz in Europe).

Variations in frequency are typically a few cycles and can be from seconds to minutes in duration.

If the frequency drops below the minimum threshold a low frequency event will be recorded; if it exceeds the maximum threshold a high frequency event will be recorded.

The factory default nominal frequency is 60Hz for 110V models and 50Hz for

220V models. However, PowerWatch can be user configured to record at

50Hz and 60Hz for either 110V or 240V models.

PowerWatch Operating Overview

54

PowerWatch synchronizes itself to the consecutive positive and negative zero crossings of the AC line (every 8.33 milliseconds). Should the voltage waveform be so highly distorted that unexpected zero crossings are detected,

PowerWatch will report a loss of synchronization relative to the measured voltage waveform. This Loss of Synchronization will be recorded as an event until such time as:

· the zero crossing distortion ends; or

· the reported voltage drops below 70V (a detected outage). In this situation, the Loss of Synchronization event will change to an

Outage event

(while keeping the original start time and duration).

PowerWatch has a resolution of 8 seconds, so events shorter than this duration will have a time stamp of "< 8 seconds".

A single impulse event between hot and neutral or neutral and ground can be displayed as a graph, enabling you to see if the impulse is causing zero crossings.

An impulse graph is produced using the amplitude, direction and position (in degrees) of the event. The graphical representation is not intended to show what the wave form looks like nor does it show the duration of the impulse.

To graph an impulse you must choose an event that contains only one impulse; it is not possible to graph an event consisting of multiple impulses .

1. With the Site Report window open at the Events tab, double-click the single-impulse event you want to graph.

(There are two other ways of opening an impulse graph: select the singleimpulse event you want to graph by clicking it, and then, either choose Single

is possible over a telephone line via two modems: a modem connected to your computer and a modem connected to the VDR at the remote site. Each modem must be configured before it can be used for communication.

The configuration instructions we give apply to the USRobotics Sportster

Many manufacturers of PC software and hardware use serial (COM) port(s). It is difficult to predict potential serial port conflicts. If the Lite-Link interface cavle's wand tip is not flashing, ther are a few steps that can be taken in order to potentially find the source of the problem.

·

Make sure that the Lite-Link interface cable is securely plugged in. The

Lite-Link may appear to be properly connected but only be partially plugged in.

·

Try a different serial port. If the PC has more than one serial port, try another port to see if the Lite-Linnk flashes.

Determine if you have any other Windows programs using the serial

port. PC faxing programs or other programs that use the COM port can cause conflicts during data transmission. To verify that no other programs are running and causing comunication problems, shut down your computer and restart if before you run the PowerWatch program.

· Verify that your serial port settings are correct. In Windows 3.1, use the

Microsoft Diagnostics program, MSD.EXE, to find out the number of installed serial ports in you PC, and their settings. These settings should be the same as those displayed in the advanced section of "Ports" in the

Windows 3.1 Control Panel. Exit Windows or restart the computer in MS-

DOS mode before running MSD. If an internal modem is used, MSD may detect the modem's serial port. This serial port cannot be directly used with the Lite-Link.

Windows 95 users can verify port settings using Device Manager. Device

Manager is found on the Task Bar by choosing Start, Settings, Control

Panel, Systems, and Device Manager.

· Verify that your serial port is functioning properly. Use any standard

Windows communications program to ensure the port is functioning.

Examples include: ProComm, Windows 3.1 Terminal or Windows 95

Hyperterminal.

Exit all programs (including PowerWatch) and connect the Lite-Link to the

port. Run the communications software and set the local echo to "off" and hardware flow control control to "none". When using Hyperterminal, choose a direct connection to the port. Open the port with the communication software.

Any alphanumeric character typed on the keyboard should cause the Lite-Link to flash, and the character to appear on the screen.

If the Lite-Link does not flash during typing, the Lite-Link may need repair.

If the Lite-Link flashes during typing, it should also work with PowerWatch software. Exit the communications program, and re-start PowerWatch. If Lite-

Link does not flash when running PowerWatch, re-install PowerWatch software.

· Check your mouse driver. Certain older or inferior drivers for mice, trackballs, and laptop "pointers" are known to interfere with serial port operation. If, after disabling your mouse driver, the Lite-Link functions normally, try using a high quality mouse driver such as Logitech or

Microsoft.

· Try another computer. An alternative to serial port troubleshooting is to use a different computer. Another computer with its serial ports set up correctly will confirm that there is an incorrect set up or software/hardware conflict with the original PC.

Verify that the printer is plugged in, turned on, and has paper.

· Verify that Windows is set up correctly. Windows uses its own printer drivers. Set up is done through the Windows Control Panel. If you need help, follow the instructions in the Windows 3.1 Guide under

Printers/Setup; in Windows 95, click Help, and choose Troubleshooting

Voltage Disturbance Recorder

PowerWatch voltage readings can be different on various meters. A

PowerWatch VDR reads voltage in average RMS, while some manufacturers' meters may calculate and display True RMS.

Date and/or time are not correct. The PowerWatch uses the PC's internal clock to reference the time of the downloaded data. Set the PC's internal clock to the current time. The Windows 3.1 User's Guide, under System

Time and Date, will explain this procedure; in Windows 95 click Help, time, and changing your computer's time. Make sure that the time format is either

24-hour or AM/PM, not both.

PowerWatch time stamps are invalid after a prolonged period of time.

To eliminate this issue, ensure that the PowerWatch VDR is cleared of data a minimum of once every four years.

Two PowerWatchs have different impulse readings on the same circuit.

Locally generated impulses can carry relatively little power. One VDR can absorb some of the energy leaving less for the next one in the series to read.

PowerWatch records long periods of large NG surge. The VDR has been plugged into a convenience outlet that has been wired with the hot and neutral lines reversed.

PowerWatch does not record any data. The VDR does not record events while communicating. Make sure that realtime display is stopped.

PowerWatch will record events in 8 to 16 seconds thereafter.
