CVT Capacitive Voltage Transformer is a step-down transformer that changes high voltage into low voltage. Capacitor Voltage Transformers transform transmission class voltages into uniformly low, readily measured values that are utilised for high voltage system metering, protection, and control. Normally, it is impossible to detect the line voltage or current in a high voltage system. …
What is Transformer Oil Testing? Transformer oil testing is analogous to blood testing for people. Transformer oil testing is one of the most well-known and effective loss prevention strategies, and it need to be a part of each organization’s maintenance schedule. In addition to serving as an early warning system, it also enables us to …

What is a Transformer? Electrical power is transformed from one circuit to another circuit using a static electrical device called an electrical transformer without affecting the frequency. Transformers have the ability to change the voltage while also altering the current. AC current is used for transmission. The transformer operates on the core concepts of electromagnetic …

What is Buchholz Relay? The transformer is safeguarded against internal faults by the Buchholz relay. It is the relay with gas actuators. Between the conservator and the main tank is where the Buchholz relay is located. Such a relay is utilised in transformers with a rating more than 500KVA. Due to financial factors, it is …
What is Three Phase? A typical technique of alternating-current electric power generation, transmission, and distribution is three-phase electric power. It is a form of polyphase system that is utilised by electrical grids all over the world to transfer power. Large motors and other heavy loads are also powered by it. Because it utilises less conductor …
Transformer Losses (Heat) The efficiency of power transformers is high, especially, for large transformers at full load. However, losses are present in all transformers. These losses may be classified as copper or I² R losses and core or iron losses.The thermal ratings of a transformer are determined by the following three factors: • the amount …
Introduction In this session we are gonna discuss about some protective devices and accessories ie used in transformers 1.Double-float Buchholz relay For sudden pressure rise and gas detection in oil-immersed transformer tanks with conservator. Installed in the connecting pipe between tank and conservator and responding to internal arcing faults and slow decomposition of insulating materials. …
