IEC 60255-1 pdf download – Measuring relays and protection equipment – Part 1: Common requirements
1 Scope
This part of lEC 60255 specifies common rules and requirements applicable to measuringrelays and protection equipment including any combination of devices to form schemes forpower system protection such as control, monitoring and process interface equipment in orderto obtain uniformity of requirements and tests.
All measuring relays and protection equipment used for protection within the power systemenvironment are covered by this standard.Other standards in this series may define their ownrequirements which in such cases shall take precedence.
For special applications (marine，aerospace，explosive atmospheres,computers，etc.), thegeneral requirements within this standard may need to be enhanced by additional specialrequirements.
The requirements are applicable only to relays in new condition.All tests in this standard aretype tests, unless otherwise declared.
