What is the Radiator of Transformer?Radiator in Transformer DefinitionA radiator in a transformer is defined as a component that helps cool the transformer by dissipating heat from the transformer oil.Importance of CoolingControlling the temperature of the oil is crucial to extend the transformer’s capacity and prevent overheating.Working PrincipleThe radiator increases the surface area to dissipate heat, aiding in efficient cooling of the transformer oil.Type of radiatorNatural air cooled radia

What is Conservator Tank of Transformer?Conservator Tank DefinitionA conservator tank is a cylindrical container on a transformer, providing space for the oil to expand and contract.FunctionThe conservator tank allows transformer oil to expand when hot and contract when cool, preventing overflow and ensuring efficient operation.ConstructionThe conservator tank is a cylindrical oil container closed at both ends. It has a large inspection cover on each side for easy maintenance and cleaning.Conser

What is Silica Gel Breather of Transformer?Silica Gel Breather DefinitionA silica gel breather is a device used to filter moisture from the air entering a transformer, protecting its insulation.Air Flow MechanismTransformer oil expansion and contraction cause air to move in and out of the conservator tank, necessitating filtration.Construction of Silica Gel BreatherThe silica gel breather for transformers is simple in design. It is a container filled with silica gel that air passes through. Sili

What are the Types of Transformers Windings?Types of Transformers Core type transformers have windings on outer limbs Shell type transformers have windings on inner limbsMainly there are two types of transformer Core type transformer Shell type transformerTypes of Winding used for Core Type TransformerCylindrical WindingsThese windings are layered type and uses a rectangular or round conductor shown in Fig.(a) and (b). The conductors are wound on flat sides shown in Fig.(c) and wound on the rib

What is Sweep Frequency Response Analysis Test ?SFRA Test DefinitionSFRA test of transformer is a method used to assess the condition of transformer windings by analyzing their frequency response to electrical inputs.Purpose of SFRA testing Assessing the mechanical integrity of windings: Detecting whether the windings are displacements, deforms or short circuits. Monitoring the health of the transformer:Changes in the condition of the transformer windings can be tracked by comparing historical d

The purpose of the pulse testDetection of partial dischargePartial discharge refers to the discharge phenomenon that occurs at the air gap or impurity in the insulation material under the action of high voltage electric field, which may gradually destroy the insulation system.Evaluate the degree of insulation agingBy analyzing the characteristics of partial discharge, you can evaluate the degree of aging of the insulation material.Identify potential insulation failuresProblems such as moisture,
