GKC433H Switchgear Analyzer

Tests the mechanical and electrical characteristics of various high-voltage circuit breakers, isolating switches, and contactors.

INSTRUCTION:

1. Test the mechanical and electrical characteristics of various high-voltage circuit breakers, isolating switches, and contactors.

2. Test parameters including closing time, opening time, asynchronous time, bounce time, pre-insertion time, and operating-coordination time for 12 main contacts, 6 contacts with closing resistors, 6 main contacts, and 6 auxiliary contacts.

3. Measure the pre-insertion time and resistance of 6 resistor contacts.

4. The panel is equipped with 12 contact status indicator lights to help determine closing/opening status and confirm correct wiring.

5. The system includes three analog transducer input channels and three digital transducer input channels. Measure stroke, penetration, rebound, overshoot time, overshoot, and operating speed of the switchgear using resistive transducers and digital transducers.

6. With digital transducers, the rotation angle of single-turn or multi-turn operating mechanisms can be measured accurately. Measurement resolution up to 0.04 degrees.
