Equipment for power transformer monitoring and diagnosis

Due to the continuous monitoring of the gas-in-oil content, moisture in the insulation system or abnormal temperature rise caused by the cooling system, a detection rate of about 70% could be considered. Assessment of bushings by monitoring the leakage currents and/or internal pressure leads us to ...
