Many DNSPs in Australia need secondar injection testing of the solar protection relay within a PVDB. We are available to carry this work out on site or complete in the factory depending on the requirements of the DNSP. Power Quality Analysis and Votlage Logging services are also available.
Injection tests include several electrical tests concerned with what happens during a Loss-of-Mains (LoM) event, and its potential impact on the network. These include over/undervoltage, over/underfrequency, vector shift, and rate of change of frequency (ROCOF).
Some of the more common protection relays that we test are: ComAp MainsPro, ComAp InteliPro, ABB CM-UFD.M33, Woodward Easyprotec
