Numerical relays are natural developments of digital relays due to advances in technology. Use of the relay The overcurrent relay REJ 523 is intended for selective short-circuit protection in medium voltage distribution networks but can also be used for protection of generators, motors and transformers. Thus, the maintenance cost can be reduced with maintained security and dependability for fault clearing. A big difference between conventional electromechanical and static relays is how the relays are wired. More complex digital relays will have metering and communication protocol ports, allowing the relay to become an element in a SCADA system. The first numerical relays were released in 1985. Overcurrent Relay Technical Reference Manual 3. ABB Transformer protection and control RET615 IEC Numerical Relay Compact and versatile sol... Rs.0 Add to Wish List Add to Compare. Conventional electromechanical and static relays are hard wired relays.Their wiring is fixed, only their setting can be manually changed. We deal as a reseller in various makes such as Schneider, GE Alstom, ABB, SEL and C&S for Numerical Relay, Switchgears, Automation Products etc. I.L. The characteristics and behavior of the relay are can be programmed. By staying here you are agreeing to our use of cookies. The first numerical relays were released in 1985. Among the protection relays there are some used for general feeder protection (protection against over-current) and as back-up protection. Numeric relays are programmable relays. The widespread acceptance of numerical technology by the customer and the experiences of the user helped in developing the second generation numerical relays in 1990. Numerical relays are based on the use of microprocessors. Most ABB numerical relays are also multifunctional. However, ABB has products for both substation wide monitoring (alarm annunciators) and power grid wide monitoring (network management systems). Electromechanical and static relays have fixed wiring and the setting is manual. A suitable test interval for numerical relays with self supervision has to be established, but test intervals of 4- 8 years are used. The relaying voltage and currents are passed through an isolation transformer. There are several multi-functional protection relays for different application ranges. www.abb.com, ABB’s Electrification Business Area is a global leader in electrical products and solutions, operating in more than 100 countries, with over 200 manufacturing sites.
