UVR-1 Universal Voltage Regulator Control Specification
The UVR-1 Universal Voltage Regulator Control is a microprocessor-based single phase step voltage regulator
control with an integrated remote monitoring and control capability supporting multiple communications protocols.
The control uses waveform sampling and digital signal processing to accurately measure and compute system
parameters. The UVR-1 is compatible with most single phase step voltage regulators from various manufacturers.
The differences in regulator types (i.e. operation counters, neutral switch/polarity, holding switch) are handled
through UVR-1 configuration selections. The UVR-1 can be ordered in panel and harness configurations that fit
existing regulator control cabinets. The UVR-1 provides the maintenance/retrofit/upgrade marketplace with a
flexible, functional step voltage regulator control including the widely used DNP3 communications protocol.
Regulation Features:
•
•
•
•
•
•
•
Bandcenter - load center set voltage, adjustable from 100.0 to 135.0 V with 0.1 V resolution.
Bandwidth - load center voltage bandwidth, adjustable from 1.0 to 6.0 V with 0.1 V resolution.
Time Delay - time delay before tap change, adjustable from 5 to 180 sec. with 1 sec. resolution.
Line Drop Compensation - allows for correction of load center voltage due to voltage drop (or rise) caused by
transmission lines or other devices.
• Resistive Compensation - resistive voltage change, at rated load current, between the voltage regulator and
the load center, adjustable from -24.0 to +24.0 V with 0.1 V resolution.
• Reactive Compensation - reactive voltage change, at rated load current, between the voltage regulator and
the load center, adjustable from -24.0 to +24.0 V with 0.1 V resolution.
Reverse Power Flow Detection/Operation - reverse power flow is detected by phase angle and real current
monitoring.
• Separate setpoints and metering data are maintained for reverse power flow (mode dependent).
• Current threshold for reverse power flow mode determination, adjustable from 1% to 10% with 1%
resolution.
• Source-side sensing transformer not required.
Multiple Modes of Operation:
• Locked Forward - regulation and metering based on forward power flow.
• Locked Reverse - regulation and metering based on reverse power flow.
• Idle Reverse - regulation and metering based on power flow direction, but tap changes do not occur during
reverse operation.
• Bi-directional - regulation and metering based on power flow direction.
• Neutral Reverse - regulation and metering based on power flow direction, but regulator returns to neutral
position during reverse operation.
• Co-generation - regulation and metering based on forward power flow, except that reverse line drop
compensation values are used during reverse power flow.
Multiple Regulation Algorithms/Timer Modes
• Sequential - When the load center voltage exceeds either band edge, the time delay is initiated. After the
time delay has expired, the appropriate raise or lower operations are performed with 2 second intervals
between, until the load center voltage is in-band. If the load center voltage returns to within the band edges
during the time delay period, the timer is reset.
• Time-Integrating Sequential - When the load center voltage exceeds either band edge, the timer (initially 0)
is incremented each second. If the timer meets or exceeds the time delay, the appropriate raise or lower
operations are performed with 2 second intervals between, until the load center voltage is in-band. If the
load center voltage returns to within the band edges during the time delay period, the timer is decremented
each second until it reaches 0.
• Voltage-Averaging - When the load center voltage exceeds either band edge, the time delay is initiated.
The load center voltage is monitored and averaged over the delay. After the time delay has expired, the
computed number of raise or lower operations is performed (up to 5, with no inter-tap delay) to bring the
load center voltage to the bandcenter. If the load center voltage returns to within the band edges for 10
continuous seconds during the time delay period, the timer is reset.

Voltage Limiting - monitors the regulator load voltage to protect customers near the regulator.
• High Limit - the regulator load voltage is not allowed above this setting. Tapchanger raise operations are
inhibited 1 volt below this setting. Adjustable from 95.0 to 135.0 V in 0.1 V increments, or can be
disabled.
• Low Limit - the regulator load voltage is not allowed below this setting. Tapchanger lower operations are
inhibited 1 volt above this setting. Adjustable from 95.0 to 135.0 V in 0.1 V increments, or can be
disabled.
• Auto-Runback - If the line characteristics change and either of the voltage limits are exceeded for a
minimum time period, the control will automatically return the regulator load voltage to within the voltage
limits.
Voltage Reduction - lowers the effective set voltage by one of three percentages selectable by external inputs†,
or by an explicit percentage set locally or remotely. All percentages adjustable from 1.0% to 10.0% with 0.1%
resolution.
Tap Position Limits for Increased Load Capability - raise and lower tap position limits, adjustable from
positions 16 lower to 16 raise.
Load Current Limit - load current exceeding this limit inhibits the automatic control algorithm and can cause
an alert. Adjustable from 0 to 440 mA CT secondary current (higher with less measurement accuracy).
Automatic Control Algorithm Inhibit - the automatic control algorithm can be inhibited for manual, auxiliary
(external)†, or direct remote control of the regulator.
Tap Position Indication - current tap position is tracked based on the neutral position indicator and
acknowledgement from the operation counter or holding switch. The tap position is maintained in non-volatile
memory, and can be set to match existing physical tap position.
Electronic Draghands - resettable electronic tap position draghands, along with the time and date of each
min/max, are kept in non-volatile memory.
Operation Counter - two digital operation counters, one resettable, are kept in non-volatile memory. The nonresettable counter may be set to match an existing operation counter for replacement applications.
External Raise and Lower Inputs and Outputs† - external motor control signals that can be used to gang
multiple regulator controls.
External Alert Input and Output† - external alert source, and an indication that one of several selectable alert
conditions has occurred.

Data Logging - up to 7 user-selectable data items may be logged on a periodic basis, and displayed or read out
via the front panel PC port. A portion of the most recent data log records are stored in non-volatile memory.

protocol data. Powerfail backup maintains clock/calendar for up to 3 days without AC power.
Ambient Temperature Monitor - present and min/max ambient temperature monitoring.
Non-volatile Parameter Storage - all configuration parameters are stored in non-volatile memory.
3 User Parameter Profiles with Selectable Date Activation - 3 user-customizable profiles for storage of
UVR-1 parameters. These can be loaded directly, and/or the date activation feature allows any of these to be
automatically loaded on any of 4 user-selectable dates each year.
Factory Defaults for All Parameters - UVR-1 can be reset to factory defaults from front panel.
Self Test and Equipment Protection - comprehensive control self test, and safeguards against equipment
damage due to conditions such as voltage transients, low tapchanger motor voltage, and stuck switches.
Tapchanger Contact Wear Log and Alert - data related to tapchanger contact wear may be logged, and
accessed via the protocol, displayed, or read out via the front panel PC port. The data is stored in non-volatile
memory. In addition, thresholds can be set to cause an alert.

Maintenance and Upgrade Path:
The front panel PC Port allows for firmware revisions as features are added or enhanced. The UVR-1 control is
designed to accommodate additional data acquisition and control functions in the future. These functions may
include event recording and protocols other than DNP3. As additional features are released, firmware and/or
hardware revisions will be announced. The main processing circuit board inside the UVR-1 is designed to be
replaceable with more powerful processors and larger program and data spaces. This provides a cost-effective
upgrade path, insuring the flexibility of the UVR-1 and protecting the original investment.
I.C.M.I. reserves the right to modify this design specification in any way it sees fit to meet corporate goals.
†Requires optional XIO Port Interface Board (or XIO Port Input-only Interface Board if only input functions are
needed), available from ICMI.
