The dual & self powered ekor.wtp protection, metering and control unit combines a full range of equipment to form comprehensive wind
turbine generator protection units.

The constantly increasing demands in wind farms result in new requirements for both MV switchgear and associated protection functions. The ekor.wtp range is designed through each phase of its life cycle to respond to the variously changing demands of a wind turbine generator: From its design phase to the operation and maintenance phase during the total working hours of a wind turbine generator, the ekor.wtp non-stopped optimizes the performance and energy production of on/offshore WTGs, improves turbine reliability and grid service capacity, while keeping them protected against electrical faults.
