Nowadays, high importance is given to low energy devices (such as refrigerators, deep-freezers, washing machines, pumps, etc.) that are able to produce reactive power in power lines which can be optimized (reduced). Reactive power is the main component which overloads power lines and brings excessive thermal stress to conductors. If the reactive power is optimized, it can significantly lower the electricity consumption (from 10 to 30%—varies between countries). This paper will examine and discuss the development of a measuring device for analyzing reactive power. However, the main problem is the precise real time measurement of the input and output voltage and current. Such quality measurement is needed to allow adequate action intervention (feedback which reduces or fully compensates reactive power). Several other issues, such as the accuracy and measurement speed, must be examined while designing this device. The price and the size of the final product need to remain low as they are the two important parameters of this solution.

This article develops an optical fiber sensor using a fiber Bragg grating (FBG) and a piezo‐electrical transducer (PZT) to measure reactive power. By mounting an FBG on a PZT bar, a dynamic strain simulator was constructed. The equivalent voltage produced by reactive power applied to the PZT was converted to the dynamic variation of the FBG Bragg wavelength. The reactive power was attained by measuring the changing value of the wavelength. Thus, the sensor can be used to measure reactive power without the use of a traditional power meter. © 2013 Wiley Periodicals, Inc.
