3 PONDVD PW41iProtective Relay Test Set PONOVO POWER CO., LTD.

PW41i Protective Relay Test Set PW41i is a reliable protective relay test set with high current output (3×40A) and high voltage output (3×300V). It is with built-in local system so that the testings could be done easily by the relay test set itself. PW41i is a favorable and economical testing solution for commissioning work in distribution grid. Features • High current and power output, output 3×40A with maximum power up to 400VA/phase • Shortcut keys to simplify operation • 8 binary inputs, 4 binary outputs • Auxiliary DC power supply 110V, ADJ(0-300V, software controlled), 220V switchover •...

PW41i is a type of relay tester controlled locally. A color screen and local control system make PW41i portable and easy to use. The local software embedded in PW41i is called PowerTestCut. There are 11 test modules in the software: Directional, Frequency Relay, QuickTest, Ramp, State Sequence, Time Inversed Current, Time Inversed Voltage, and Time. Frequency Relay QuickTest[4V,3l) QuickTest(ZJ Const] QuickTest(Z,V Const] QuickTest(Z,Zs Const] Ramp(3l] State Sequence(4V,3l] Time Inversed Current Time Inversed Voltage Time > Frequency Relay ❖ Can search maximum torque angle and two boundary angles...

> QuickTest (Z, I Const) ❖ 4 voltage / 3 voltage and 3 current sources available for test relay ❖ Amplitude, phase angle and frequency of voltage and current sources can be controlled independently ❖ Test can be in manual or auto mode ❖ Easy to test impedance relay with constant current ❖ Set the fault impedance and fault current, obtain the amplitude and phase angle of each phase voltage and current according to the fault type ❖ Can manually or automatic search the relay operation value > QuickTest (Z, V Const)> QuickTest (Z, Zs Const) ❖ Easy to test impedance relay with constant voltage ❖ Set...

> State Sequence (4V, 3I) ❖ Specially designed to realize RAMP for different test applications, such as pick up/drop off value checking, directional relay testing, maximum torque angle checking etc. ❖ Both pulse ramp and linear ramp available ❖ Can search the relay operation value automatically ❖ Used to define multiple continuous state sequences for special test applications, such as generate a series of states to test the tripping time and close time ❖ 4 voltage / 3 voltage and 3 current sources available for each state ❖ Trigger condition in each state can be set separately > Time Inversed...

PW41i Protective Relay Test Set  Time About templates  Used to test trip time of protection relay  Various value can be set separately, such as fault types, fault time, the voltage and current at pre-fault and fault state, etc. PW41i supports using relay templates in its local system for testings, which includes more than 400 available relay types for engineer’s use for their testings.
