FAQs:
Q: What is this device mainly used for testing?
A: It is mainly used for mechanical characteristic testing of high-voltage circuit breakers, including parameters such as opening/closing time, synchronization, operating speed, travel, and closing resistor.
Q: Can the analyzer test both opening and closing operations?
A:Yes. The instrument supports testing of both opening and closing operations of high-voltage circuit breakers. During the test, it records the corresponding operating time and mechanical characteristics and displays the results and waveforms for analysis. This allows technicians to evaluate the complete operating performance of the breaker rather than checking only a single operating action.
Q:Can the instrument measure the operating speed of a circuit breaker?
A:Yes. When equipped with the appropriate travel measurement sensor, the analyzer can measure the movement of the breaker mechanism and calculate its operating speed. Speed measurements can help technicians analyze the opening and closing movement of the contacts and identify changes in mechanical operating characteristics.
