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 a Current Transformer ?Current Transformer DefinitionA current transformer (CT) is defined as an instrument transformer where the secondary current is proportional to the primary current and ideally has zero phase difference.CT Accuracy ClasThe accuracy class of a current transformer measures how accurately the CT replicates the primary current in its secondary, crucial for precise metering.Working PrincipleCurrent transformers operate on the principle of a power transformer, where the p

What is Electric Power Transformer?Power Transformer DefinitionA power transformer is a static device that efficiently transfers electrical energy between circuits without changing the frequency, using electromagnetic induction.Main Technical Parameters Rated voltage Rated power Rated current Voltage ratio Turns ratioVoltage AdjustmentPower transformers modify voltage levels to enhance energy efficiency and safety in power transmission and distribution.Core and Shell Types Step-up and step-down
