Inquiry Form

The protective relay tester is an important testing tool that ensures power system is running securely and reliably. JB series protective relay testers are computer-based, true color LCD graphic display and WOS, Windows operation system. It is compact, portable and light weight, 16Kg to 18Kg.

Main Features of Protective Relay Tester
1. Operation system: built-in computer, WOS.
2. Simultaneously output available: 6 current and 6 voltage (some code is 5 voltage, 3 current)
3. Max. phase current output: 30A; Max. phase voltage output: 130V
4. High accuracy outputs: better than 0.1%
5. 8 Binary inputs, 4 Binary outputs
6. Adjustable threshold (0-250V) for Binary inputs
7. 640*480 dots 8” big size LCD display
8. Advanced testing and data management software, test results can be automatically managed and recorded as test reports.
9. Keyboard/mouse interface, two USB and two RS232 interfaces
