Motor Current Measurement and Analysis

This measurement can be applied with circuit breakers equipped with a spring energy storage system and spring release mechanism. During spring drive motor current measurement, the current signature curve of the spring charging motor is recorded. The recording allows for analysis of the inrush and steady-state currents as well as the spring charging time.
