Testing of associated control and protection equipment • Motor Protection • Feeder Unit Protection • Busbar Protection • Generator Protection • Translay • Buchholz • Synchronising Devices • Tripping & Control Equipment • Transformer Protection Protection relay technology has advanced dramatically over the years offering the end user a complex array of features. Often the relays will however only require a fraction of the settings available to be utilised. Protection relays whether they are of the electro-mechanical or microprocessor based are precise measuring devices and require periodic testing to prove correct functionality. PRSS can provide full maintenance/servicing/commissioning of many types of protection relays and devices (old and new) manufactured by companies such as ABB, AEI, Alstom, Areva, Asea, BBC, Brown Boveri, CEE, Combiflex, GEC-Alsthom, P&B, Reyrolle, SEG, Siemens, Stromburg, and VA-Tech, to name but a few.
