In utility and industrial electric power transmission and distribution systems, a numerical relay is a computer-based system with software-based protection algorithms for the detection of electrical faults. Overcurrent Relay Technical Reference Manual 3. Site commissioning is usually restricted to running the in-built software self-check, verifying that currents and voltages measured by the relay are correct, and exercising a subset of the protection functions. By staying here you are agreeing to our use of cookies. our ethical business strategy, nominal price, honest dealing, well-planned ship facility has assist to us in prominent position in the market. The first numerical relays were released in 1985. Flexibility and Reliability of Numerical Protection Relay (on photo: ABB’s numerical relay type SPAD 330 C designed to be used as a fast interwinding short-circuit and interturn fault protection for two-winding power transformers and power plant generator-transformer units. The relay provides an optimized composition of protection, monitoring and control functionality in one unit, with the best performance and usability in its class. Thus, if a numerical 87T differential relay is directly applied for the overall differential protection of a PAR, and set to compensate for vector group Yy0, the false differential current will appear as soon as PAR phase angle shift is different from zero degrees. APPLICATION OF NUMERICAL RELAYS FOR HV SHUNT REACTOR PROTECTION Z. Gajić, B. Hillstrőm, M. Kockott ABB Automation Technologies AB Vasteras, Sweden ABSTRACT Viewed in the substation yard, an HV, oil immersed, shunt reactor does not differ much from a power transformer, but in reality it is not that simple. The feeder terminal REF 542plus, like its predecessor REF 542, combines measurement, monitoring, protection, control and self diagnostics in one package. RET630 is a comprehensive transformer management relay for the protection, control, measurement and supervision of power transformers, including step-up transformers, and power generator-transformer units in utility and industrial power distribution systems. Thus, the maintenance cost can be reduced with maintained security and dependability for fault clearing. In addition to protection, measurement, control, condition monitoring and general functions, the REF 545 feeder terminals are provided with a large amount of PLC functions, which allow for several automation and sequence logic functions, needed for substation automation, to be integrated into one unit. Further, the LON communication together with the PLC functions minimizes the need for hardwiring between the feeder terminals.
