Medium Voltage Temperature Measurement
OSENSA’s PRB-GB3 medium voltage fiber optic temperature sensors install on switchgear contacts, bus
bars, cast resin transformers, motors, and generator windings to provide reliable 24/7 thermal monitoring with
noise-free performance. The probes are constructed from durable, high dielectric strength materials and
have been tested to safely operate on equipment rated up to 38 kV (3 phase)1
. They install quickly and can
be ordered with optional probe-tip attachments suitable for various applications.
