Protection relay maintenance
ABB relay service support for the entire life cycle
All electronic devices are subject to wear and tear. Harsh environmental and physical conditions such as varying temperature, humidity, pollution and interference affect the aging of electronic components, which increases the likelihood of relay malfunction after several years in service.
ABB has developed a preventive maintenance concept for the well-established SPACOM and RE500 series relays. These relays have been in the market for more than 20 years. The preventive maintenance concept provides a cost-effective solution for extending the life cycle and thereby maintaining the same protection capability of the relays.
