Substation Maintenance/Switchgear Factory/Power Equipment Testing
The HGKC-12 Circuit Breaker Characteristics Tester is a professional-grade device designed for on-site and factory testing of high-voltage circuit breakers. Equipped with a high-performance industrial embedded platform, it delivers high-speed data acquisition & analysis, withstanding strong electromagnetic interference (up to 500kV) to ensure stable and accurate results in harsh substation environments.
It supports simultaneous testing of multiple dynamic & mechanical characteristics, including opening/closing time, velocity, synchronization, stroke, bounce, and coil current, meeting the diverse testing needs of SF6, vacuum, and oil circuit breakers. The built-in isolated adjustable DC power supply enables automatic/manual control of switch operations (open/close/reclose), while comprehensive user-defined functions adapt to various switch models.
