Self-inspection and self-confirmation before use [Harmonic measurement during the installation of solar power generation].
We will conduct harmonic measurements as part of the "pre-use self-inspection and pre-use self-confirmation" items required when installing new electrical equipment.
"Measurement of Power Quality" involves conducting on-site measurements and surveys for distributed power sources, such as solar power generation, to assess harmonics and other factors. We analyze measurement values and waveform data to provide data submissions and advice for resolving issues. If the measured harmonics exceed specified values, we can also offer guidance for resolution. As a partner company of the Central Research Institute of Electric Power Industry, we have been engaged in testing operations for distributed power sources, including solar power generation, for many years. We have experience conducting tests under various conditions and confirming and reproducing various phenomena. We have a track record of performing harmonic measurements for "self-inspection before use and self-confirmation before use" during the installation of solar power systems related to government agencies. <Features> - Advice on issues such as PCS error stops and malfunctions of leakage circuit breakers - Guidance on how to address PCS error codes For more details, please download the PDF and view the brochure.

basic information
■Overview Our company, as a partner of the Central Research Institute of Electric Power Industry, has accumulated measurement technologies and testing know-how for distributed power sources, including solar power generation, over many years. Based on our experience in certification testing for solar power generation, we measure power quality at the site and provide advice aimed at estimating the causes of issues based on the measurement results. ■Measurement Items 1. AC Voltage - Instantaneous value, effective value, imbalance, harmonics (0 to 50th), total harmonic distortion rate 2. AC Current - Instantaneous value, effective value, balance of each phase, harmonics (0 to 50th), total harmonic distortion rate 3. Active Power (Generation Amount) 4. Reactive Power 5. Power Factor 6. DC Voltage 7. Transient waveforms at the time of abnormal shutdown We will conduct on-site measurements and provide advice aimed at estimating the causes of issues based on waveforms and numerical data.
