Design and Implementation of Low Cost Distribution Transformer Monitoring System For Remote Electric Power Grid
In normal ways all the Industrial or Electrical machineries are controlled by the manual operation. Hence there
is step by step progress but most of the time there is not actually instant co-operation between system and operator in case of
emergency or fault type situation .Therefore we are designing a system where there exits communication between system
and operator. For this we are using Transformer, microcontroller, analog to digital converter. As we know Distribution
transformer is a major component of power system and its correct functioning is vital to system operations. To reduce the
risk of unexpected failure and the ensuing unscheduled outage, on-line monitoring has become the common practice to
assess continuously the condition of the transformer with. This paper presents design and implementation of a system to
monitor and record key operation of a distribution transformer like overvoltage, over current, temperatures, rise or fall of oil
level which based on Wireless protocol. Sensors, including a Temperature Detector and a Liquid level sensor performs
according to manufacturers’ specifications are calibrated and tested by power distribution monitoring offices. The system is
installed at the distribution transformer site and by measuring above parameters it will help the utilities to optimally utilize
transformers and identify problems before any catastrophic failure.
