Product Profile of Numerical Sync-Check Power Protection Relay
Numerical Sync-Check Power Protection Relay is designed for Definite Time Sync-Check Protection for paralleling two power source and enables adjustment for Phase angle limit over the range of 1 to 90 degrees. The Sync-Check Power Protection Relay has 9 optically isolated digital status input for monitoring of status and avoids use of external relay logic. Numerical Sync-Check Power Protection Relay is manufactured by Ashida Eletronics Pvt. Ltd., an ISO 9001:2008 recognised company.
Ashida Eletronics Pvt. Ltd. also manufactures a wide range of electrical power protection relays, auxiliary protection relay and SCADA systems. The Numerical Sync-Check Power Protection Relay is available with online display of line voltage and bus Voltage, CB status and other digital and physical status.
Salient features of the Numerical Sync-Check Power Protection Relay:
Time delay is adjustable over a range of 1 to 99 cycles or 0.1 to 99 seconds.
Voltage monitoring circuits provide independent determination of Bus-A and
Bus-B or Bus-A to Bus-B voltage levels for selectable closing conditions.
Voltage difference provides additional verification of proper breaker closing conditions.
Large 20x4 LCD display for Parameter and setting display
Fully communicable with IEC standard open protocol.
Separate Communication Prot for SCADA [RS485] as well as Local testing [RS232C]
Very low burden on PT [less than 0.2VA]
Continuous monitoring of module`s internal hardware and alarm generation in case of failure of any critical components.
Digital Output contacts for local alarm as well as tele-signalling
9 Optically isolated digital status input for monitoring of status and avoid used of
external relay logic
100 nos of event memory Sync digital status change relay pkp etc. All events are with date and time stamped up to 1ms.
