HISAC 0604 Circuit Breaker Operational Analyser

The HISAC 0604 Circuit Breaker Operational Analyser

is a specialized diagnostic instrument used to evaluate the operating performance of medium-voltage (MV) and high-voltage (HV) circuit breakers. It is designed for field testing, commissioning, troubleshooting, and preventive maintenance of electrical switchgear systems.

This analyzer measures essential breaker performance parameters such as:

• Main contact timing
• Auxiliary contact timing
• Opening and closing time sequence
• Trip and close coil current waveforms
• Static contact resistance of breaker poles

The HISAC 0604 combines multiple testing functions into a single portable device, reducing the need for separate instruments. It enables engineers to perform comprehensive breaker diagnostics quickly and accurately, ensuring reliable switchgear operation in critical power systems.

Its rugged portable design makes it suitable for use in substations, power plants, and industrial electrical maintenance environments.
