INSTRUMENT TRANSFORMER Introduction: Transcript
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. 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 Total .

The objective of this class is to provide the student with a general knowledge of the fundamentals of transformer protection. Enabling Objectives. an. Instrument Transformer ?: . It is a transformer that is used in conjunction with any measuring instrument (i.e., Ammeter, Voltmeter, Wattmeter, Watt-hour-meter, …etc.)or protective equipment (i.e., Relays). . The modern digital technology has modified the requirements for instrument transformers used for measurement and protection applications.The modern secondary equipment does not need the high power out The performance of a transformer can be calculated on the basis of equivalent . circuit.The. . four main parameters of equivalent circuit are: . - .
