Monitoring of transient overvoltages on the power transformers and shunt reactors – field experience in the Croatian power transmission system

, 2017
Power transformers and shunt reactors may be subjected to various dielectric stresses such as lightning and switching overvoltages. Since the exposure of equipment to overvoltages during operation and the overvoltage amplitudes are usually unknow, an on ...
