CT or PT functions on the principle of electromagnetic induction. The electrical energy is first converted into magnetic energy and again the magnetic energy is converted in the electrical energy. The electrical current first converted in magnetic energy. The magnetic energy is nothing but converting electrical current into flux. The flux then flow through the core. The core of the CT or PT has its maximum flux carring capacity.…Continue
In general battery acid refers to the electrolyte in a lead acid battery. That is a diluted form of sulfuric acid (H2SO4) in water generally in the concentration of 36–40%. As such it does not have the burning properties of concentrated sulfuric acid.
Battery acid is rather unique in battery electrochemical systems because it not only carries ionic…Continue
The insulation class of the transformer refers to the max (hot spot) temperature that can be safely withstood by the specific insulation material. It is the weakest of the materials used in transformer (as far as temperature withstand capability is concerned) as the other materials like steel core & copper winding can withstand much higher temperature during operation. There are different classes of insulation materials (Y, A, B, F, H & C) with max temperatures 90, 105, 130,…Continue
