Description
The fault indicators are protected against the influence of adjacent phases, and the threshold is selected automatically by the AutoRANGER function. Resetting is done by current or by voltage. TPR models are installed on 15, 25 and 35 kV cable joints. RadioRANGER allows reading indicator status in manholes by radio from the surface, without sending personnel down. The submersible design suits flooded manholes, per IEEE 495.
