IEC 60255-26 Measuring Relays and Protection Equipment - Part 26: Electromagnetic Compatibility Requirements

EUROLAB laboratory provides testing and compliance service within the scope of IEC 60255-26 standard. The IEC 60255-26 standard applies to measuring relays and protection equipment, taking into account combinations of devices to create schematics for power system protection, including control, monitoring, communication and process interface equipment used with these systems.

IEC 60255-26 Measuring Relays and Protection Equipment - Part 26: Electromagnetic Compatibility Requirements

This standard specifies electromagnetic compatibility requirements for measuring relays and protection equipment. The tests specified in this standard are not required for equipment that does not contain electronic circuits, such as electromechanical relays.

The requirements specified in this standard are applicable to measuring relays and protection equipment in new condition and all tests specified are type tests only.

Emission

The purpose of this standard is to specify limits and test methods for measuring relays and protection equipment in relation to electromagnetic emissions that may cause interference with other equipment. Test requirements are specified for the enclosure and auxiliary power supply ports.

These emission limits represent electromagnetic compatibility requirements and have been chosen to ensure that disturbances produced by metering relays and protection equipment normally operating in substations and power plants do not exceed a certain level that could prevent other equipment from functioning as intended.

Immunity

This standard specifies immunity test requirements for measuring relays and protection equipment with respect to continuous and transient, conducted and radiated disturbances, including electrostatic discharges.

These test requirements represent electromagnetic compatibility immunity requirements and have been chosen to provide an adequate immunity level for relays and protection equipment normally operating in substations and power plants.

Safety aspects are not covered by this standard. In special cases, situations will arise where disturbance levels may exceed the levels specified in this standard, for example when using a handheld transmitter or a mobile phone in the vicinity of measuring relays and protection equipment. In these cases, it may be necessary to use special precautions and procedures.
