TK8100 Calibrator for Low-voltage Circuit Breakers

TK8100 Calibrator for Low-voltage Circuit Breakers

TK8100 is a high-precision and fully integrated calibration system designed for intelligent low-voltage circuit breakers. It supports the full verification of electrical measurement, communication protocol, alarm triggering behavior, and intelligent protection functions.

The system integrates a three-phase precision AC power source, a built-in high-accuracy three-phase standard energy meter, a calibration bench, computer control, and dedicated testing software. Its modular platform structure makes it ideal for laboratory, manufacturing, and research environments.

TK8100 is suitable for establishing a comprehensive test station for circuit breakers at D-level and below in power utilities, electrical equipment manufacturers, calibration centers, and R&D institutions. The system provides stable output, reliable test automation, and supports standardized test reports and traceable calibration procedures.
