Frequently Asked Questions
A switchgear analyzer measures circuit breaker timing and mechanical motion. The results help verify that contacts open and close in synchronization and support assessment of breaker operation.
The GKC433D is designed with high-immunity circuitry for reliable testing in high-EMI environments, including those commonly found in high-voltage substations.
Yes. The GKC433D can test mechanical characteristics on manually operated breakers and includes a built-in DC output for motor driving and current curve measurement.
The analyzer supports resistance (analog) and digital (RS422) transducers for measuring motion parameters such as travel, overshoot, and angle.
The analyzer stores up to 60 results in internal memory. Data can be transferred via USB disk or managed on a Windows PC for analysis and A4 report generation.
Contact bounce indicates repeated contact movement during operation. Measuring it helps assess contact performance and the circuit breaker's mechanical operation.
