Various methods are used to detect when to switch from star to delta. Historically, in manual starters, the changeover is determined by the operator watching the ammeter until the current has dropped to a low level, or listening to the sound of the motor until the speed becomes steady. Autom...
The ammeter is used to measure the short circuit current, and the voltmeter is used to measure the voltage across the primary winding. Cooling System Failure The majority of all power and distribution transformers are oil immersed with different types of cooling depending on their size. As the ...

In the measurement of large alternating currents a current transformer is usually interposed between the circuit whose current is to be measured and the ammeter so as to step the current down to a value suitable for the instrument. The ratio between the circuit current and the meter current is...
