ENSORS
AP900 series provides choice of different types of arc sensors to be utilized in different units
and different switchgear types according to specific application requirements. Available sensor
types are arc light point sensors and arc light fiber optic loop sensors.
Arc light point sensors are typically installed in metal clad compartments providing quick
accurate location of the faulted area. Arc light fiber loop sensors are installed typically to cover
a wider protected area with one fiber when no need for more exact fault location exists. The
detailed instructions are described in “Arc Sensors Series – Instruction booklet”.
