The REG-DA Relay for Voltage Control & Transformer Monitoring left the factory in a condition that fulfils all relevant safety regulations. Generally transformer windings are immersed in insulation liquid and covered with paper insulation, hence it is impossible to measure the actual winding temperature in a de-energizing transformer at time of transformer winding resistance measurement. The definition of 'commissioning' is not standardized, but generally covers all activities after all components of the wind turbine are installed. Mainly two types of transformer testing are done at manufacturer premises-type test of transformer and routine test of transformer. Oil-filled transformers, HV bushings, and circuit breakers may require conditioning of the insulating oil to remove vapors and water. 2 That the current transformers are of the correct ratio and.
