They are able to set and test digital relays, select current and voltage transformers, determine relays and transformer taps, conduct research on power system protection, and test their protection design schemes in a laboratory environment. In this laboratory students are familiarized with overcurrent, overvoltage, distance, and differential relays as well as pilot relaying. Students perform experiments on transmission, distribution, generator, and transformer protection. Experience will be gained in configuring and operating test equipment (60Hz voltage and current signals, as well as digital representations of those signals), calculating test quantities, making connections between relay and test sets, and analyzing results including all available sources of fault records (relay targets and internal oscillographic records). Students gain familiarity with test equipment and procedures when testing modern microprocessor-based multifunction transmission, generator, motor, and bus protection relays. Relays are tested using SEL AMS low-level testing systems or Omicron CMC 256, and a Real-Time Digital Simulator. In this laboratory students set the relays using a personal computer, application software, and communication processor.

The GPS units are available for stamping data received from PMUs and relays for IEC 61850 testing.

The testing equipment such as Omicron 256, Real-Time Digital Simulator, Opal-RT, are used for dynamic relay testing, IEC 61850 testing, and real time simulation of the power system. These relay stations are setup with breaker simulators, GPS units, Phasor Measurement Units (PMUs), and residential smart meters. It is composed of seven stations with state of the art relays donated from well know relay manufactures such as ABB, GE Multilin, and Schweitzer Engineering Laboratories, such as line distance relay SEL 411L and GE D90 Plus, differential relay 487E, and transformer protection relay ABB TPU 2000R.

The laboratory features the latest in power protection relays and test equipment, including transmission line protection relays with 61850 networked communications.
