The dielectric strength of transformer oil is known as BDV or break-down voltage. A Transformer Oil BDV test is performed to find the dielectric strength of transformer oil. BDV is the minimum voltage to withstand the capacity of transformer oil…
Transformers are said to be connected in parallel operation when their primary connected to a common supply and secondary connected to a common load. The function of the transformer is to deliver power to the locality, city. But in some cases, a…
The transformer is the main device of the transmission and distribution network hence its reliability is important in every aspect. The transformer must be able to deliver the required power to load. single transformer unit is used for distribution purposes…
The Scott connection of the transformer is a standard method of connecting two single-phase transformers to perform the three-phase to two-phase conversion and vice versa. Scott connection of transformer is also known as T – T connection. In Scott-T connection, two…
Transformers play an important role in electrical power distribution and transmission systems, as they facilitate step-up and step-down voltage for distribution and transmission purposes. Because of its electricity to be transmitted efficiently. To protect transformers, various devices are fitted on…
What Is Buchholz Relay? Buchholz relay is a mechanically operated relay that is used to protect the transformer from internal faults that occur inside the transformer tank like an inter-turn fault. Buchholz relay is an oil and gas-operated device. The…
Auto transformer is a transformer in which part of the winding is common to both the primary winding circuit and a secondary winding. In normal two winding transformers, primary and secondary winding are electrically isolated but in the case of an autotransformer,…
Transformer oil testing is a crucial part of transformer maintenance, as the oil serves as electrical insulation between the winding and tank and acts as a cooling agent. Over time, the oil can become contaminated, which can degrade its insulating…
The vector group of transformer shows the phase difference between the primary and secondary sides of the transformer. There are different ways in which transformer high voltage and low voltage winding is connected. Based on HV and LV winding connections,…
The efficiency and regulation of the transformer can be calculated using open circuit and short circuit test on the transformer but to measure temperature rise during operation, it is necessary to conduct a full load test on the transformer. for…
