With the changes to AS/NZS 4777:2015 the grid-connected solar systems above 30kW must install grid protection relays and requires secondary injection testing to prove that the correct operation of the protection relay as per the parameters set by the DNSP. Some DNSP’s also require power quality readings with the solar system connected and disconnected as part of their requirements to solar systems.

Power Quality Testing

• FLUKE 435 Series2 Power Quality and Energy Analyzer is one of the top in the market we use to do the power quality test
• This testing is the analytics of harmonic distortion, voltage, current monitoring, power factor, frequency changes and waveform measurements, etc
• With the analysis of the required standards, a comprehensive report will also be submitted
