Protection relay based HiZ

High impedance (HiZ) fault detection to reduce risk of fire ignition

HiZ algorithm detects and trips for high impedance faults caused by downed conductors.

Innovative algorithm for detection of downed conductors which have fallen on surfaces with high resistivity
Detect faults not detectable by conventional ground fault methods
Reduces the risk of fire ignition by de-energizing a broken conductor as soon as it comes in contact with high resistivity surfaces
Algorithm runs on the protection device itself without the need of any additional hardware or special sensors
Helps the utility to save human lives, protect nearby animals and lessen the risk of vegetation fires caused by prolonged arcing
