Prior to commencement of transformer installation work, all shop drawings will be processed and submitted for approval by consulting engineer. Shop drawings will include front and side views of the equipment, overall dimensions, components identity, components type and ratings, electrical characteristics, incoming
Below is the list of some important transformer tests which are conducted on site before final testing and commissioning is planned. Insulation resistance test In this test the insulation resistance is measured by applying appropriate voltage across the terminals as mentioned below:
Isolation Transformers are used in order to achieve many purposes and most important of them is the safety of the transformers, equipment they are feeding and of course safety of human involved. As you are aware that transformer is electrical device that
Buchholz Relay Circuit is used for Transformer Protection, as we know there are many defects and dangers during the operation of power transformer that need to be addressed and necessary measures to be taken. Some of the hazards to transformer protection include overheating, over
Electrical functional testing is very important and critical part of any electrical project. Most of the times it is necessary to hire a third party in order to conduct the function testing of electrical systems. Big electromechanical companies are having their own
There are many different tests for the transformers depending upon the usage, type and size but most common tests are: Short Circuit Test Open Circuit Test Let us first understand that what does short circuit and open circuit means in electrical transformers:
