EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ANSI C37-90 testing. This standard specifies standard service conditions, standard values, performance requirements, and test requirements for relays and relay systems used to protect and control power apparatus. A relay system may include computer interface equipment or communication interface equipment, such as a carrier transmitter/receiver or tone equipment. Basically industrial control does not include relays designed for switching communications or other low-level signals, or any other equipment not designed for the control of power devices.
Service conditions, electrical ratings, thermal ratings, and test requirements are defined for relays and relay systems used to protect and control power devices. This standard provides a common repeatable basis for designing and evaluating relays and relay systems.
There is a need for assurance that electronic relays and relay systems will operate satisfactorily when installed in the harsh environment of a substation or switchyard. Standard surge tests will provide assurance that relays and relay systems will withstand a certain level of surge.
The use of proper grounding and shielding techniques when installing the equipment will reduce the actual level of overvoltage striking the equipment. However, even with proper grounding and shielding, fluctuations above the test levels specified in this standard can reach the equipment. In such cases, it may be necessary to add external surge protection devices to the relay system by the user.
