Constant power transformer
Web2) Voltage sag compensation: The current distribution transformers and systems cannot correct the voltage level to ensure a constant voltage at the user terminal. Future transformers should have this characteristic. 3) Power failure compensation: the transformer takes power from the energy system for power failure compensation WebIf the transformer is equipped with a constant oil pressure (COPS) oil preservation system, mount the support structure for the COPS tank, mount the tank and install the valves on the main tank and the COPS tank. The valve to the COPS piping on the transformer cover should remain closed. The detailed illustrations for mounting and
