Protective relays and devices must be tested and functionality proven at certain intervals during the life of the equipment. However, when planning or carrying out primary plant maintenance the protection element is easily overlooked.
As a major Original Equipment Manufacturer (OEM) of both HV and MV switchgear, Hawker Siddeley Switchgear (HSS) offer a comprehensive service of protection and control equipment testing irrespective of whether the equipment is electro-mechanical, electronic or micro-processor based (programmable) type.
HSS Site Service personnel work throughout the world as part of an OEM and have the full support of our experienced technical, production and test departments in the factory. Our field engineers will resolve problems at site or report any unusual findings to the supporting staff back at the factory who are available on request to rectify any problematic situations with technical solutions.
As an OEM, the factory has specialist testing facilities; ensuring that protection and control relays are fully operational and compliant with calibration criteria and specifications. Primary/Secondary current injection of protection relays (and associated CTs) ensure that relays are compliant with calibration criteria and specifications.
HSS will advise you of faulty equipment and offer a choice of options to correct the situation. As a result of this we offer the additional service of retrofitting new protection relays and control schemes to older types of switchgear irrespective of who manufactured the original equipment.
