Ponovo PW336i Protection Relay Tester
 

PW336i protective relay tester is the best economic model with 6 current channels 

and  4 voltage  channels,  capable  of automatic  testing  different kinds  of  protection relays,  such  as  distance,  overcurrent,  frequency,  directional,  time 

inversed,  line-differential, differential relay easily without changing cable 

connection, etc. 

It's  the  ideal  test  device  for  all  power  utilities,  power  plants,  relay manufacturers,  panel  manufacturers,  research  institutes, universities, testing companies, etc. 

Features

1. 6*15A, 4*150V
2. Aux DC (0-300V), DC measuring inputs
3. 8 binary inputs, 4 binary outputs
4. Adjustable threshold (0-400V) for binary inputs
5. Built-in analog monitoring and recording function
6. Can support the test of IEC61850 complied relay
7. More than 500 relay templates offered free of charge for different relay templates to do automatic testing
8. Support to import CSV, RIO and XRIO files

In‐built analog monitoring & recording unit 

This  in‐built  analog  monitoring  and  recording  unit  samples  the  actual  current/voltage  outputs  and  real‐ time output waveform can be displayed in the software. 

This  makes  it  easy  to  check  the  correctness  of  wiring  before the test and observe the output during the test  process. 

Real‐time  output  waveform  display  helps  the  fast  troubleshooting of wiring and test circuitry before test  is actually started. User can also use this provision to  analyze  the  external  signals,  such 
as  phase  angle,  power, harmonic,

IEC 61850 Function

PW336i provides analog voltage/current signal  to relay and the GOOSE message from relay is 

received and analysed by relay test equipment. 

Main Specifications

The PW336i can be used for various kinds of relay testing including:
