Measuring relays and protection equipment -
This part of IEC 60255 specifies common rules and requirements applicable to measuring
relays and protection equipment including any combination of devices to form schemes for
power system protection such as control, monitoring and process interface equipment in order
to obtain uniformity of requirements and tests.
All measuring relays and protection equipment used for protection within the power system
environment are covered by this standard. Other standards in this series may define their own
requirements which in such cases shall take precedence.
For special applications (marine, aerospace, explosive atmospheres, computers, etc.), the
general requirements within this standard may need to be enhanced by additional special
requirements.
The requirements are applicable only to relays in new condition. All tests in this standard are
type tests, unless otherwise declared.
