Why areElectro-mechanical Relays
Still in Use?
Electro mechanical contacts are the preferred output devicefor all major protection relay manufacturers for numerousreasons including:
SimpleReliableCompactLow costElectrical isolationHigh switching capacity for sizeC/O contacts available
Why are Additional RelaysExternal to the Protection Relay
Required?
Integrated protection & automation schemes retainsignificant demand for relay output contacts;
As more functions are incorporated into fewer numericprotection relays the number of relay outputs available isoften not sufficient;
To enable simple diagnosis of system faults through therelays non volatile flags;(Particularly at sites where SCADA is not installed)
Why are Additional RelaysExternal to the Protection Relay
Required?
The miniature relays in numeric protection relaysdo not offer the functionality requirede.g. mechanical lockout contacts, non volatile flags;
Internal low duty output relay contacts are not visible orreadily serviceable;
Failure of an output contact in a numeric protection relay willbe expensive to rectify & may require return to the factory.
What are the FunctionalRequirements for the External Relays?
Large number of contacts SELF RESET AND LATCHING
High switching capacity DC BREAK RATING
High level of isolation between coil and contacts
High visibility flag indicator SELF RESET AND LATCHING
Secure mechanical LOCKOUT FUNCTION
Time delay on drop off function SLUG TIME DELAY
High and low operating burden options
What are the Desirable AttributesFor the External Relays?
High security (No false operation)
High reliability (Simple solid construction)
High speed operation
No contact bounce
Wide range of contact configurations
Wide voltage operating range
Modular configuration for flexible panellayout & circuit design
High packing density to reduce panel space
Short delivery lead times and reasonable cost
All Attributes Met Using6R MATRIX System
Modular Construction
Pre-Defined Relay Elements
The 6R MATRIX system was developed as a modular range of auxiliary relays to provide a complete solution for protection engineers.
The pre-defined function versions are intended to:
Simplify specification & ordering
Reduce cost due to model rationalization
Provide a cross reference to other manufacturers
Standardise the wiring
Three Relay Functions
Tripping relays
Auxiliary relays
Trip circuit supervision relays
High Speed Multi Trip
<10ms operating time including bounce
Anti bounce buffers
High burden & low burden types
Latching or self reset contacts
Latching flags with large target window

A significant safety feature is the fitting of internal resistors to limit the trip coil current to well below the circuit breaker trip coil operate current, should the relay be accidentally short circuited.
