Product Description

4U4I Distribution automation terminal tester/Optical digital relay protection tester

Product overview
Automated test solution: to achieve the distribution network 10~35kV automatic terminal equipment protection function, "three remote" performance, 101/104 communication protocol, feeder automation and other functions of automated testing, high precision, fast speed, convenient transportation.

One-key automatic test for distribution automation terminal equipment (DTU, FTU, TTU, fault indicator) without manual intervention.

Complete the functions of virtual master station and monitoring master station, complete the function test of communication, joint adjustment and point in single-machine mode.

Synchronous fault simulation of multi-point DTU/FTU and TTU terminals is realized without power outage, fault area judgment, fault isolation and power supply recovery strategy execution are carried out with the main station, and complete feeder automation (FA) function test is realized.

It can customize the test scheme library for different terminals, intelligent matching and one-click testing during testing, and generate standard test reports.

Support IEC101, IEC104 and other communication protocols, and import the protocol point table of major distribution automation terminal manufacturers with one click.

It can read the fault recording data file, playback the action behavior and inversion function in the case of fault waveform.

4 channels 264V voltage, 4 channels 30A current output (short time 100A output), accuracy up to 0.05 level.

4 channels of voltage, 4 channels of current sampling, sampling accuracy up to 0.5%8 channels open.

Route 8 out; The opening speed can reach 0.1ms; Open access supports adaptive active and passive input.
