INSTALLATION AND MAINTENANCE GUIDELINE FOR PROTECTIVE RELAY SYSTEMS

How many years should relay protection systems be replaced

On average, mechanical relays typically last between 1 to 5 years due to their moving parts, which are prone to wear and tear. Typically, the electrical life expectancy of general-purpose and power relays is rated at a minimum of 100,000 operations. Network operators need to have a long term maintenance and replacement strategy for protection relays. 10 years from the start of the Classic stage, although exceptions to this may occur if components or technologies needed are no longer available to ABB.

Regular maintenance of relay protection devices

The maintenance activities for protection relays can be categorized into three main areas: visual inspection, functional testing, and calibration. Rare operation, critical function: Protective relays may operate only once every several. If applicable, documentation is required detailing how verified protection segments overlap to ensure there is not a gap. ABB has developed a preventive maintenance concept for the well-established SPACOM, RE500 and Relion series relays.

What are the relay protection design systems

Relay protection is the discipline of designing schemes that detect faults, coordinate relays, and isolate equipment without outages. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.
