Switchgear engineering firm NOJA Power has announced the release of a new firmware upgrade package for the company’s RC10 and RC15 recloser controllers. This optional upgrade to the firmware adds ANSI 81R Rate of Change of Frequency (ROCOF) Protection, ANSI 78 VVS Voltage Vector Shift Protection and ANSI 50 BF Circuit Breaker Failure functionality to the extensive suite of functionality available in the controller. The relay version is designated 22.214.171.124 and is available from the company’s South African distributor RWW Engineering.
Although the update is entirely optional, it is free to all users of the company’s RC10 and RC15 controllers. This update will allow these recloser controllers to meet the protection requirements of the vast majority of renewable energy connection sites. Both VVS and ROCOF protection are deployed for anti-islanding purposes, and are passive protection techniques designed to detect the load/generation mismatch that occurs in most islanding scenarios. NOJA Power have released a concept primer on both VVS and ROCOF.
