In general terms, optical sensors are suitable for remote monitoring as it possible to position them several miles from the measurement point and also measure simultaneously more than one quantity value.

Signal multiplexing is also an important application of optical technology, allowing the use of several sensors along a single fiber cable, thus creating a sensor network.

The fallowing quantities can be measured:
     • temperature
     • Mechanical stress
     • Vibration
     • Shift
     • Electrical fields
     • Pressure and acceleration

Optical sensors developed for the alectrical industry

Transmission line monitoring:
     • Ampacity
     • Strength
     • Vibration

Generation process monitoring:
     • Partial discharges
     • Vibration
     • Proximity of generators

Sub-central offices monitoring:
     • Temperature
     • Power transformer partial discharges
