What is the different of induction transformer and automatic transformer?
Neither of these terms is normally applied to a transformer. You may be thinking of a 'mutual tranformer' and an 'autotransformer'. If so, then a 'mutual transformer' is a transformer which has electrically-isolated primary and secondary windings, whereas an 'autotranformer' (the term, 'auto', is misleading and has nothing to do with the transformer being 'automatic'!) has a common and series winding, meaning that the primary and secondary sides are electrically connected to each other.
What is VA burden in electrical engineering?
The term 'burden' is used to describe the secondary load applied to an instrument transformer; the reason for this is so that it is not confused with the 'load' supplied by the high-voltage circuit to which the transformer's primary is connected. A burden is either a measuring instruments (ammeter,voltmeter, wattmeter, etc.) or protective relay, depending on the function of the instrument transformer. 'V.A' is the symbol for 'volt ampere', which defines the 'power' rating of the instrument transformer.
What is the difference between VT and PT transformer?
Both are same.AnswerA 'PT' is a 'potential transformer', the preferred term in North America, for what is termed a 'VT', or 'voltage transformer', in Britain. Two names for exactly the same instrument transformer.

What does aerokinesis mean?

What does the term proper mean when applied to certifying official?
the funds are appropriated for payment
What do you mean by discrimination of a transformer?
The term, 'discrimination', is applied to fuses. This describes the requirement for any fuse closer to an overcurrent fault to clear that fault within the time necessary for a second fuse, closer to the supply, to operate. This minimises the number of circuits disrupted in the event of a overcurrent fault.
What does the term proper mean when applied to Certifying officials duties?
the funds are appropriated for payment
What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer

What does the term historical thinking skills mean?
Historical thinking skills refer to the abilities to critically analyze, evaluate, and interpret historical events and sources. It involves examining evidence, constructing arguments, and understanding historical context to make sense of the past. These skills help individuals develop a deeper understanding of history and its impact on society.
