What is an Oil Surge Relay

Oil-immersed transformers are critical components in power distribution systems. These transformers handle high voltages and play a crucial role in ensuring reliable electricity supply. One essential auxiliary device used in these transformers is the Oil Surge Relay (OSR). In this blog post, we’ll explore what OSRs are, how they work, and their significance in protecting transformers. … Read more

Open and Short Circuit test of Transformer

Open and short circuit tests are carried out to determine the equivalent circuit parameters of a single phase or 3 phase Transformer. An open circuit or the OC test of a transformer is used to measure “CORE losses“. Whereas the Short circuit or SC test of a transformer is used to measure the “Full load copper loss“. Open circuit or OC … Read more

What-is-a-transformer

Continuous Electro-mechanical energy conversion takes place in an Electrical Machine. The transformer is not an Electrical Machine. It is a static device, that does not convert electrical energy to mechanical energy and vice versa. In Short, a Transformer is a thing in an electrical component that Steps up or down the voltage. The Step-up transformer increases the … Read more

Efficiency of Transformer

Introduction Efficiency is a crucial aspect of any industry, and the transformer is no exception. In the electrical power industry, transformer efficiency is defined as the ratio of the output power to the input power, typically expressed as a percentage. A transformer with high efficiency is able to transfer more power from the input side … Read more
