    EasyGrid User Guide 11.5 Sensor Handling until Routing The sensors are typically quite long (from 3m up to 15m) and it is advisable to coil as much of the sensor as possible in loops no smaller than 15 cm for ease of handling. The coil can be attached with cotton strapping or string (do not use nylon cord, as over tightening it can break the fiber).

    EasyGrid User Guide 11.7 Probe Routing Assuming the sensor exits the winding along the winding leads, the sensors can all run along the top of the windings to one wall of the tank. Note that this routing should be done only after the winding and core assembly have been installed in the tank, the idea again being to keep as many sensor installation steps as possible until a maximum of the other fabrication steps have been done.

    EasyGrid User Guide 11.8 Tank Wall Assembly Installation The EasyThrough is installed on the tank wall of the transformer and, once the core and windings have been installed in the tank, the sensors are routed and connected to the EasyThrough. Successful installation requires both careful planning prior to installation and thorough understanding of certain basic properties of fiber optic sensors by all employees expected to handle the sensors or the windings once the sensors have been installed.

    EasyGrid User Guide 14 Gallium Arsenide Principle 14.1 Gallium Arsenide Theory 14.1.1 The Principle FISO’s fiber-optic temperature sensors, for high voltage temperature measurement, are based on white light absorption/transmission by a GaAs (gallium arsenide) semiconductor. The effects of temperature variations on this semiconductor are well known and predictable. As the temperature of the semiconductor increases, the semiconductor’s transmission spectrum (i.e.

    EasyGrid User Guide 14.1.2 The Temperature Sensor The TPT-62 sensor is based on direct contact temperature measurement. Traditional temperature sensors like thermocouples and RTDs (resistance temperature devices) work on the same principle. In other words, the semiconducting material must be touching the object or immersed in the liquid or gas to be measured.
