Solutions for Troubles with Solar Power Generation: Power Quality Measurement 'On-Site Inspection'
Power quality measurement
Is the state of solar power generation perfect? We can provide advice for addressing issues through on-site measurement and analysis! We will leverage our years of experience in research and testing of decentralized power sources!
"Measurement of Power Quality" involves on-site measurements and surveys of distributed power sources, including solar power generation, analyzing measurement values and waveform data to provide advice for resolving issues. [Advice for Troubleshooting Solar Power Generation and Other Issues] By using measurement equipment for power quality, we can address issues that may show good values in "tester measurements" or "insulation resistance measurements"! As a partner company of the Central Research Institute of Electric Power Industry, we have been conducting testing operations for distributed power sources, including solar power generation, for many years. Through various testing conditions, we have confirmed and reproduced various phenomena, accumulating knowledge, technology, and know-how, enabling us to find solutions for various issues. <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 - Solutions for issues like solar power generation not producing electricity For more details, please download the PDF and view the brochure.
