Description
The HCB-14 Circuit Breaker Analyzer is a high-precision, portable test system designed for comprehensive mechanical and electrical characteristic testing of high-voltage circuit breakers. Adopting a 32-bit high-speed acquisition chip and advanced signal processing technology, it accurately captures dynamic parameters during breaker operation.
Engineered for 0.4kV–500kV power systems, it supports vacuum, SF6, oil, and GIS circuit breakers. It measures timing, stroke, speed, acceleration, contact resistance, and coil current with high accuracy. The 7-inch touchscreen displays real-time curves and data, while the rugged IP67 enclosure ensures reliability in harsh field environments. Ideal for power utilities, switch manufacturers, and test institutions for factory testing, commissioning, and preventive maintenance.
