PPT-Transformer Oil Insulating and Cooling

Medium Silica Gel Taking Oil Sample oil Sample 2 Interfacial Tension Test Omicron Oil Training Dielectric breakdown ASTM D877 amp D1816 The  dielectric breakdown  is an indication of the oils ability to withstand electrical stress The most commonly performed test is ASTM D877 and because of this it is more readily used as a benchmark value when comparing different results The oil sample is placed in a test cup and an AC voltage is impressed on it The electrodes are two discs exactly 1 in in diameter and placed 010 in apart. Oils which meet the same specification and class type are miscible in all proportions However when oils mixed as per the above guidelines the mixture should meet the respective standard used In case of mixing unused oils of different origin class PRESENTED BY.

Transformer is a device which works on the principle of mutual induction. . Principle. . of operation. It is based on principle of . In electrical power system the range of current and voltage is very high and so it is not possible to measure these values directly by any meter of reasonable size and construction.. So there is a need to step down these voltages or currents to such a value so that it can be easily measured.. The transformer is a static device which is used to transfer electrical energy from one ac circuit to another ac circuit. . Input to a transformer and output from a transformer both are alternating quantities (AC).. El-Sharkawi@University of Washington. 2. Why do we need transformers?. Increase voltage of generator’s output. Transmit high power at low current. Reduce cost of transmission system. Adjust voltage to a usable level. PREPARED BY:. VRUNDA RANA (131130107049). KRIMA .
