Abstract :
A novel electro-optic hybrid instrument for current measurements is presented. Compared with other hybrid instruments for current measurements, this instrument provides the simultaneous measurement of four parameters: current value and frequency, phase differences in 3-phase power line and the temperature of the wires. Due to the special processing algorithms implemented the need of ADC and microcomputer is discarded in the remote module. Thus power consumption of the remote module is minimized allowing for the use of cost effective components for optical powering and providing the explosion safety in hazardous areas.
