What is terrafocs?

TerraFOCS is an all fiber optic current sensor module which measures online partial discharge current  on a ground conductor AND zero sequence current flow on an earth-grounded neutral conductor, making it the world's first integrated optical partial discharge and ground fault sensor for power distribution switchgear!

TerraFOCS:

 

 

Ground CT's supply valuable information about online power system activity, yet these critical sensors are often not installed in power distribution systems, simply because of the extra cost associated with wiring an induction CT into the ground connection of a power system node. 

 

OpticAmpere's TerraFOCS system provides online measurements of partial discharge current through an equipment ground conductor or cable shield ground, while also measuring grounded-neutral conductor current to detect load imbalances indicating phase ground faults, and may be installed with small form factor inside switchgear cubicles, with galvanic isolation, and only requires a fiber optic cable link to integrate with an existing SCADA relay network backplane. 

 

This passive sensor configuration and associated ease of installation enables online PD monitoring, for improved predictive maintenance, and earth-grounded neutral current measurements which are directly observed in real time and not derived from sequence network calculations for improved ground fault detection.
