GKC433DR Switchgear dynamic resistance analyzer

1. GKC433DR is used for testing electrical and mechanical characteristic of high voltage circuit breaker, switch and contactor.
2. Measure the time parameters (close, open, asynchronous, bounce, pre-insert time) of 12 main contacts and 6 resistive contacts. Measure the co-operate time between 6 main- and auxiliary contacts.
3. Measure the resistance and pre-insert time of 6 resistive contacts.
4. Set with 12 contact state indicator lamps on panel. It is easy to judge close and open state.
5. There are three analog input channels and three digital input channels. Measure the motion travel, over-travel, rebound, overshoot and speed of the CB by using resistance or digital transducers.
6. Use a digital rotary transducer for measuring single or multi turn operating mechanism. Resolution is up to 0.04°.
7. Operate Close, Open, O-C-O, O-C, C-O control sequences.
8. Test the mechanical characteristic operated by breaker manually.
