A multifunction optoelectronic measurement system for ac three-phase networks

A new measurement system is considered that contains a fiberoptical waveguide that implements galvanic isolation (separation) between measurement and operator areas (zones) serves for transferring (transmitting) measurement information from the measurement area to the operator area, as well as for transferring optical radiation in the measurement area. The energy of this optical radiation is converted to the electrical energy to supply (power) at the circuit of the remote module (unit). In contrast to known hybrid measurement systems for measuring the current strength, this system enables the measurement of a number of the parameters, namely, the current, frequency, phase, and temperature of a current-carrying wire.
