Notes
Before test, ground the main machine to avoid inductive static electricity that might
occur on the running tester.
Be careful of voltage output, especially over 36V, to aviod electric shock hazards.
The voltage and current output terminals of the tester should NEVER import other
voltage and current sources. During test, if the testing protection equipment
feedbacks the voltage to the tester, it might cause damage. So be careful.
Break off the outside circuit of the protection equipment to ensure the accuracy of
the test. Besides, ground the voltage N and current N at the same point.
The tester is only used as a testing tool for the protection equipment. DC power
supply (0-300V, 150W) could offer DC power supply for the protection equipment but
not for the protection circuit.
There are some heat sinks for wind ventilation located on the front, back or bottom
of the main machine. Don’t cover or block the heat sink, which might cause unusual
situations.
The machine could not be located in an open place that might catch raining.
Collect the main machine into packing box when not in use. For cleaning the
machine, unplug electronics firstly and then use cleaner or stupe to do it.
Handle the computer with care, and assign special staff for that.
When the device works abnormally, please contact the factory and don’t try to fix by
your own.

1. Characteristics and Technical Parameters
1.1 Characteristics
1.1.1 The signal processing platform is built on latest United States DSP and integrated
with advanced FPGA technology, which offers strong signal processing ability.
1.1.2 The amplifier has smooth and real output waveform without burrs , which is high
performance and extremely reliable and not like switch amplifiers that easily produce
high-order harmonic. It doesn’t have the burr problem that might cause inaccurate settings,
so it gives great measuring accuracy on broad-use high-performance quick protection
equipments.
1.1.3 The real and accurate small current wave causes no electromagnetic pollution and
won’t interfere any electrical devices on the test site.
1.1.4 The Ia, Ib, Ic indication lights on the panel will flame in certain combinations to identify
current distortion situations caused by open circuit or overload resistance of the current
source type current output circuit.
1.1.5 Under voltage distortion situations caused by short circuit or overload of the voltage
source type voltage output circuit, the distortion detection circuit will automatically shut
down the voltage amplifier and flame the indication light on the panel to identify short-circuit
of voltage output. If the short-circuit or overload situations were fixed, the voltage amplifier
will recover to work automatically.
1.1.6 Binary inputs can be electrically isolated from each other and compatible with dead
contacts and 15V-220V DC potential. The potential polar can be automatically identified,
which gives lots of benefitial to application and field wiring.
1.1.7 The manual soft startup mode improves the reliability of the power and shield the
impact on the testing protection equipment and electric network when startup, so that it
protects the testing machine from mis-startup because of turning on/off the tester.
1.1.8 Mass wind-cooling heat sink has separated wind tunnels and electronic parts
mounted on the electrical board inside the machine case, and formed negative voltage to
resist the pollution of harmful gas and dust to keep long-term cleaning inside the case. Its
5
PW431D User Manual
intelligent wind system can control the wind volume according to the temperature sensor
mounted inside the case. Under normal working situation, the wind system works at a quiet
and low speed. When the temperature inside the case was rised up to 50℃, the wind
system will speed up to largely upgrade its heat dissipation ability. The delicate structure
and heat dissipation design not only improves the equipment’s ability to tolerate heavy-load,
large current and long-time working but also its stability and reliability.

27
PW431D User Manual
6.2 Parameters
1. Fault Type: A-phase earthing, B-phase earthing, C-phase earthing, AB short-circuit, BC
short-circuit, CA short-circuit, 3-phase short-circuit
Short-circuit impedance, impedance angle: amplitude value and phase of short-circuit impedance
in fault.
2. Short-circuit current: It's the magnitude of fault phase current when the tester outputs fault.
According to short-circuit current, short-circuit impedance, impedance angle, zero-sequence
compensatory coefficient KO, it can automatically calculate the fault phase voltage.
3. Maximum fault time: It’s the time from the fault starting to the end of the test, including trip time,
reclosing time and permanent trip time, with the default value of 5s. The maximum fault time has
the logical OR relationship with the time that the binary input of the tester receives the protection
trip contact. For example: The tester will cut off the current as soon as it receives the outlet contact
that has 50ms; if the contact didn't connect to the tester, the fault current will continue to be
outputted till the maximum fault time 5s is reached.
4. K0 Calculation Method: KO is the zero-sequence compensatory coefficient. Since it's different
from different manufacturer, select the right one, otherwise it will affect the earthing impedance
calculation. There have 3 methods:

KL is for Nanjing Automation Research Institute (NARI) , and RE/RX is for Sifang Automation Co.,
Ltd and Guodian Nanjing Automation Co., Ltd.
5. PT position: The trip phase voltage will recover to the rated voltage before fault when the tester
receives trip signal if the bus side is selected; the trip phase voltage will have no output when the
tester receives trip signal if the line side is selected.
6. Breaker Trip/closing Time Simulation
Trip Time: When the tester receives the protection trip signal, it will switch the phase voltage and
current of the tripping to the after-trip state after the trip time.
Reclosing Time: When the tester receives the protection reclosing signal, it will switch the voltage
and current to the after-reclosing state after the reclosing time.
7. Fault Property: For the permanent type, the tester will give the fault selected as soon as receiving
the reclosing signal; for the transient type, the tester will output the rated voltage and 0A of current
as soon as receiving the reclosing signal. Note: If the permanent fault type is selected, the reclosing
contact under protection must be connected to the binary input D or H of the tester.
8. Binary-out Action: ABC 3-trip, ABC 1-trip, EFG 3-trip, EFG 1-trip
Reclosing: D, H
If the split-phase tripping is selected for the protection, the trip A, B and C contacts to be protected
should be connected to the corresponding A, B and C binary inputs of the tester; if the 3-phase trip
28
PW431D User Manual
is selected, the trip contacts under protection could be connected to any of A, B and C binary inputs
of the tester randomly. During the setting check, the outlet strap will open, the contact should be
empty or one end of it connects to tripping and closing positive terminal and another end connects
to the protection outlet, which should be via the ABC binary input on the front panel of the tester;
during the switch transmission, enable the tripping and closing of the outlet strap, one end of the
binary input connects to the positive power of the tripping and closing and another end connects to
the protection outlet, which should be via the EFG binary-in on the back of the tester.

7. State Sequence Test
7.1 Overview
This unit can control complex process flexibly: it can define 8 continuous testing states at most that
can be set of its voltage, current amplitude and phase at will, switching among states by time or
triggered by binary input.
7.2 Parameters
1. Total Number of States: 2-8 states are applied for setting. Control the function key of “Next State”
on the right bottom of the screen to view and set any state parameters.
2. Trigger Condition: It's the condition to decide when this state should be ended.
Time Trigger: It's used to define the output time of this state, which will go to the next state when the
State Time is finished.
Contact Trigger: When the binary input of the tester receives the protection action contact, this state
will be ended and move on to next state.
3. Trigger Contact: There have 4 choices of A, B, C, ABC. When ABC is selected, ABC is in the
logical OR relationship, which means only when the binary input A, B, C of the tester all receive the
action contact at the same time, this state will be closed and move on to next state.
4. After-trigger Delay Time: It's applied in the breaker tripping and closing delay situation. When the
trigger condition is reached, this state won't move on to next state until the delay time is passed.

8. Inverse Time Current Protection Test
8.1 Overview
This unit is to test inverse time current protection with 2 types of methods of list and diagram to
display the result. The test point can be set by users.

1. Variables: Ia, Ia+Ib, Ia+Ib+Ic
When Ia+Ib is selected: Ia and Ib have the same phase value and are connected parallel to each
other, which can output 2 times of maximum single-phase current at most. PW40D can output 80A,
and PW30D can output 60A. By then 1-10 test points' currents are set to the sum of Ia+Ib.
If Ia+Ib+Ic is selected: Ia, Ib and Ic have the same phase value and connected parallel to each other,
which can output 3 times of maximum single-phase current at most.
PW40D can output 120A, PW30D can output 90A. By then 1-10 test points' current is set to the sum
of Ia+Ib+Ic.
2. The number of test points: 10 at most
3. Before-fault Time: It's the period during which the tester can output the 3-phase voltage setting,
and by then the current output should be zero.
4. Maximum Fault Time: It's the maximum period during which the tester can output the current via
certain point, which should be larger than the maximum action time of each current point. When
certain current point’s protection acts before the maximum action time, the tester should stop this
current output immediately and go to the output breaking time.
5. Output Breaking Time: It's the time when the voltage and the current have zero output, which is
applied to protect complete reset action.
6. Anti-shake Time: It's the time when the tester is trying to avoid any contact shaking. If the
continuous closing time of the contact is less than the anti-shake time, it's not believed that the
contact is closed well.
7. 3-phase Voltage: It's the voltage that has been outputted before and during fault. The phase
sequence is positive, Ua=0°.

1. Protection Setting Information: Low-cycle setting: 49Hz, action time setting value: 2s, slip
blocking value: 2Hz/s, line voltage blocking value: 60V, current blocking value: 1A.

5. When the test begins, the tester will output 100V positive-sequence line voltage, 1.2A Ia, 50Hz
frequency for 3s; after the 3s, the frequency will decrease at the settled step of 1Hz/s; when it

it will stop time counting and record the action time. If the protection won’t work and the time has
elapsed for 1.2 times of the setting time, the test will stop. In order to avoid the too-low blocking
protection caused by over-low frequency, the minimum frequency limit of the tester is set to 45Hz,

can be calculated as line voltage =68V and should be larger than 60V low-voltage blocking value
(line voltage). If the protection doesn’t act, it will decrease the phase voltage continuously to 39V
and hold the value for 0.6s again, and this process will repeat till the over-current protection is
enabled by the voltage. By then the tester will stop working and record current voltage value. In the
foregoing voltage changing process: Ia=1.2*4A=4.8A , ϕ (Ia) =-60.0°: current=1.2 times of the
current setting value, and the most sensitive angle should always attain the direction condition.

4. Fault Udc: Maximum value: DC300V
5. Fault Ia: Maximum value: 20A
6. Fault time: It’s the period during which the fault voltage and the fault current have been outputted,
which should be larger than the exit time of the relay.
When the test begins, the tester will output the variables in their before-fault states. It will start
outputting the fault states and time-counting when the before-fault time is reached. When the
binary inputs of the tester being connected to the action conatact stop testing, it will record the
action time.

15.2 PGPS02-GPS-based
Synchronization Device
15.3 IRIG-B Based
Synchronization Device
It provides GPS synchronization signal in PPS
(pulse per second) or PPM (pulse per minute)
for synchronized test. Trigger time can be set
locally.
It converts external IRIG-B signal into trigger
pulse to synchronize several of our relay test
equipment for synchronized test application.
SAG0102 PIRIG-B
SAG0101 PGPS02
You can synchronize two or more PONOVO
test sets by connecting a PGPS
synchronization unit to each of the test sets’
inputs.
For detailed information about the PGPS,
please refer to the PGPS User Manual, the
product catalog, or the PONOVO Web site
www.ponovo.com.cn
Via the PIRIG-B interface box users can
connect devices to the PW431D test set that
either transmit or receive the IRIG-B time
reference signal (DC level shift protocol B00x).
That way, two or more PONOVO test sets are
synchronized.
For detailed information about the PIRIG-B,
please refer to the PIRIG-B User Manual
