Basic Protection

An ACR is a complete protection system consisting of:

  • Measurement sensors such as CT and VTs.

  • A protection relay capable of detecting, locating and initiating the clearing of a fault.

  • Switchgear capable of breaking fault current.

Some of the protection elements of the PowerLogic ADVC Controller are current operated such as Phase Over current, Earth Fault, SEF, and NPS.

Some are voltage operated such as Under and Over Voltage (UOV) and Under and Over Frequency (UOF).

Some types of protection use both current and voltage elements such as Directional Protection and Blocking.
