Abstract
A voltage sensor and the method for compensating installation position variation thereof are disclosed. The voltage sensor may comprise a casing, two substrates, a plurality of voltage sensing units and an iterative operation unit. One side of the casing may include two grooves. The substrates may be respectively disposed in the grooves, and an accommodating space is formed between the substrates. The voltage sensing units may be disposed on the substrates to measure a plurality voltage parameters of a dual-wire power cable disposed in the accommodating space. The iterative operation unit can be disposed in the casing and connected to the voltage sensing units, wherein the iterative operation unit can perform an iterative operation process according to a compensation database and the voltage parameters for compensating the horizontal and vertical displacements occurring when installing the voltage sensor on the cable, and calculate the estimated input voltage of the cable.
