Smart Metering and Health Monitoring of Distribution Transformers Using RF Technology
Abstract
Abstract
The main objective of this paper is to design and develop an intelligent energy metering system and health monitoring of distribution transformers and monitoring it real time on PC using RF wireless technology. The primary circuit range of distribution is 11 to 22KV. The distribution branded as the distribution transformer which is installed near the consumer’s sites with the range of 240/415V three-phase four wire. About 75% of the total system losses occur during distribution. More than 90% of system faults are in the distribution area. So if the fault occurs at or near the distribution transformer this will not be known by the substation automatically, nearby consumers has to inform them. Even a small fault may lead to a very big loss. In order to overcome these faults, monitoring of distribution transformers is very essential. In this project various parameters like current, voltage, temperature, power etc., of the distribution transformer are monitored and the data is sent to the sub-station. Also, this provides hardware kit of Intelligent Energy Meter (IEM) for superior metering and billing system also controls power theft. The proposed system uses RF based system for the continuous monitoring and recording of energy consumption thus helping in energy auditing. The recorded data is sent continuously for every interval of time using RF and the data are stored in the database in the Electric Board (EB) substation.
