Further Information

This is a classroom based course with practical training exercises to underpin knowledge gained.

Why does ASET’s Power System Protection (Protection Relays) course differs from that of its competitors in Scotland? Unlike our competitors ASET uses up to ten different types of protection relays which include a range of Static, Electro Mechanical and Micro Processor relays which offer:

  • EF/OC Protection
  • Generator Protection (Field Failure and Reverse Power)
  • Motor Protection (Thermal Protection)
  • Transformer Protection
  • Voltage Dependent O/C Protection
  • Trip Circuit Supervision
  • Lock Out

Target Audience
Target Audience

Electrical personnel involved with the operation and maintenance of power system protection schemes.
