The relay is housed in a robust enclosure with carrying handle. The module mounts on the desk area of the Protection and Relay Test Set, and connects to the test set using a multi-core cable and safety leads. 
An entry-level three-phase and earth fault overcurrent relay presented in an educational format. Supplied with Lss Africa Protection and Relay Test Set, the relay enables investigations into protection and monitoring of transformers, transmission lines and distribution schemes. 
This relay is also an optional ancillary for selected products in Lss Africa Power Systems range. 
The relay module is based on the industrial relay. The lecturer or student sets up different fault circuits on the Protection and Relay Test Set. They then use the keypad and display on the relay module to program it to the settings needed for the tests. They can also use the relay support software (supplied with the Protection and Relay Test Set) and a suitable computer to program the relay module. The relay module is then connected to the fault circuits so tests can be performed. 

Connection to the experimental circuit is via current transformers with ratio to suit the inputs of the relay. This provides an effective demonstration of the effect of current and voltage transformer ratio, connection and rating on protective relays.

Most tests are performed using single relays. However, there are enough connections on the Protection and Relay Test Set to test two relay modules at the same time. The main functions of the Overcurrent and Earth Fault Relay include:
High impedance restricted earth fault
Three-phase earth and overcurrent: three independent stages. The first stage selectable from any of 12 IDMT curves; the remaining stages having a direct time characteristic 
Thermal overload protection
Broken conductor detection 
Selectable blocking
Undercurrent
Negative-phase sequence overcurrent: two independent stages
Trend, fault and disturbance records
Circuit monitoring
