Modification of the operating point of residual current transformers for high frequency earth fault currents detection
Abstract
For protection against electric shock in low voltage systems residual current devices are commonly used. However, their proper operation can be interfered when earth fault current with high frequency components occurs. Serious hazard of electrocution exists then. One of the most important element of residual current devices is a residual current transformer with iron core. Tripping characteristic of residual current devices strictly depends on the operating point and properties of the current transformer. This paper presents problems of the operation of the residual current transformer in presence of high frequency current components.
