SYSTEM AND METHOD FOR MONITORING AND CONTROLLING A TRANSFORMER

摘要

A system, a method and a computer program to monitor a plurality of transformer operating parameters, as well as to accurately control one or more of the transformer operating parameters. Also, the system and method may calculate loss of life and give diagnosis for recovery and provide maintenance notification, along with monitoring the operation of the LTC.

主权项

1. A system for monitoring operating parameters of a transformer, the system comprising:
a temperature sensor that measures temperature in the transformer and outputs a temperature signal; a winding current sensor that measures current in the windings of the transformer and outputs a current signal; and a processor that wirelessly receives the temperature signal and the current signal, wherein the processor calculates a percentage loss of life values of the transformer based on a plurality of: the temperature signal, the current signal, a thermal capacity of the transformer, oil and winding-time constants, winding gradients, and ambient temperature.
