The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible still in operation. Thus, protection schemes must apply with very pragmatic and pessimistic approach to clearing system faults. The devices that are used to protect the power systems from faults are called protection devices.

For the purposes of Networks, protection devices are commonly:

  • Voltage Stability and surge control
  • Current/Voltage protection solutions
  • Lightning protection solutions
  • Earth Fault protection solutions
  • Switchgear Design and Implementation
