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.
