[Advice on Solutions] Power Quality Measurement: "The circuit breaker is tripping!"
Power quality measurement
Are you having trouble with the leakage circuit breaker stopping during the operation of the solar power generation PCS (power conditioner)? [We can provide advice on solutions!]
"Power Quality Measurement" involves conducting on-site measurements and field surveys at distributed power sources, such as solar power generation, analyzing measurement values and waveform data, and providing advice for resolving issues. [Advice for Cases Where the Residual Current Device Stops] If you are experiencing issues with the residual current device stopping, various causes may be considered, including problems with the commercial power supply, poor construction quality, or failures in the PCS (Power Conditioning System). However, identifying the exact cause is not easy. With years of experience in measurement technology and testing know-how related to solar power generation, we have tackled such issues. We analyze quality through power measurement 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 the residual current device. - Guidance on how to address PCS error codes. - Measurement using power quality measurement equipment × knowledge and experience × know-how → advice on solutions.
