[Advice on Solutions] Power Quality Measurement: "The circuit breaker is tripping!"

Are you having trouble with the circuit breaker stopping during the operation of the solar power generation PCS (power conditioner)? [Advice for a solution is available!]

"Measurement of Power Quality" involves on-site measurements and field surveys of distributed power sources, including solar power generation, analyzing measurement values and waveform data, and providing advice for resolving issues. [Advice for Cases Where the Leakage Circuit Breaker Stops] If you are troubled by the leakage circuit breaker stopping, various causes can be considered, such as issues with the commercial power supply, poor construction work, or failures in the PCS. However, identifying the cause is not easy. With years of experience in measurement technology and testing know-how related to solar power generation, we have dealt with such issues. We analyze the quality through power measurements and provide advice on solutions. <Features> - Targets cases where causes cannot be identified through tester measurements or insulation resistance measurements. - Advice on issues such as PCS error stops or malfunctions of leakage circuit breakers. - Guidance on how to address PCS error codes. - Measurement using power quality measurement equipment × knowledge and experience × know-how → advice on solutions.
