There is a code of practice that sets out safety distances and that must be followed: New Zealand Electrical Code of Practice for Electrical Safe Distances. This Electrical Code of Practice (Code) sets minimum safe electrical distance requirements for overhead electric line installations and other works associated with the supply of electricity from generating stations to end users. Distance relaying is used to detect faults on long-distance lines, pinpointing not only the fault condition but also measuring the distance between the current sensing mechanism and the fault location in the wire. Our advanced distance protection relays offer field-proven experience with sophisticated algorithms and protection characteristics such as quadrilateral, polygon or mho which are well known for their high performance in complex applications. 'Direct contact' and 'indirect contact' are now designated 'basic protection' and 'fault protection'.
