This part of IEC 60255 specifies common rules and requirements applicable to measuring relays and protection equipment including any combination of equipment to form a distributed protection scheme for power system protection such as control, monitoring and process interface equipment to obtain uniformity of requirements and tests. The standards covers main technologies used today other emerging technologies will present specific EMC and safety issues but the philosophy in this document should be applied. All measuring relays and protection equipment used for protection within the power system environment are covered by this document. Other documents in this series can define their own requirements which in such cases take precedence. The typical locations for measuring relays and protection equipment are where protection of electrical equipment is required: generally power stations, substations and industrial locations. Measuring relays and protection equipment installed in special applications (marine, railways, aerospace, explosive atmospheres, computers, etc.) could be enhanced by additional requirements required by that application.
