Benefits and Opportunities of the Wireless Technology Utilization for High Voltage Circuit Breaker and Power Transformer Test Instruments

Abstract

High-voltage circuit breakers (HVCB), as well as power transformers, as a part of substations, undergo numerous tests during their lifetime. The first test is performed in the factory. The following is the acceptance test performed at a customer site after the delivery. The most numerous are maintenance tests performed during equipment services. All the mentioned tests require an appropriate connection between a test device and a test object, usually utilizing a large number of cables. This can be very time consuming and imposes an additional risk of obtaining appropriate measurement and assessment indices. This paper presents the potential of the wiring replacement by the wireless connection between the test object and test equipment, which would simplify, improve make the test preparation procedure and packing test equipment more convenient and faster.
