Abstract

A three-phase electrical loss reduction device was invented to reduce current leakage from the transformer to the neutral wire in a three-phase, four-wire electrical system, caused by unbalanced current usage. The device consists of a plastic box containing a coil. The coil is made of copper conductor wire and contains a U-shaped iron plate and a spring. Both ends of the coil's wires are outside the box and connected in parallel to the low-voltage neutral wire from the transformer, installed on the neutral wire closest to the transformer. The three-phase electrical loss reduction device generates a current in the opposite direction to the leakage current in the neutral wire, or negative feedback, reducing the leakage current. The result is electricity savings of approximately 10 to 30 percent.

Claims (1)

1. The loss reduction device in a 3-phase electrical system consists of a housing (1) which is a rectangular plastic box with holes. Its specific characteristic is that it contains a coil (2) made of copper conductors, which is wound into a cylindrical coil with 9 to 18 turns. The diameter of the coil is 37 millimeters. The two ends of the coil are placed outside the box through the holes (10) for connection to the neutral wire of the electrical system. Inside the coil is a U-shaped steel plate (3) with a spring (4) attached between the two ends of the steel plate inside the coil.
