Your question is rather oddly phrased as, obviously, there are countless ways in which you wouldn't use a potential transformer! It's much easier to explain why you would us a potential transformer. A potential transformer (known outside North America as a 'voltage transformer') is classified as an instrument transformer, which means that its output is used to drive instruments, such as voltmeters and (the voltage coils of) wattmeters, etc., or to provide inputs to protective relays. It's function is twofold: (1) to reduce the high voltage of the circuit to which its primary winding is connected to a lower voltage which can be 'read' by a voltmeter, etc., and (2) to electrically-isolate its secondary circuit from the primary circuit for the purpose of safety.
What else can I help you with?
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What is difference between interposing voltage transformer and potential transformer?
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the full form of CT PT transformer?
CT=========current transformer PT=========potential transformer these are the instrumental transformers.
How potential transformer works explain with circuit diagram?
A potential transformer steps the high voltage down to a level of 120 V to measure them safely and easily.
Can a distribution transformer be used as a potential transformer?
I'm not quite sure what you mean by a "potential transformer", but I look at it this way: The transformer isn't aware of the purpose to which you're putting it, so no matter what you call the function, the transformer continues to perform it ... transforming voltages and impedances in proportion to the turns ratio, and currents in proportion to its inverse.
What is the difference between capactive voltage transformer and potential transformer?
A capacitive voltage transformer (CVT) uses a (usually two) stacks of capacitors to reduce the votlage to a smaller internal potential transformer (PT). This makes them less expensive than an equivalent PT, but there can be a loss of accuracy.
Can you use a 75 watt equipment on a 50 watt transformer?
No, using a 75-watt equipment on a 50-watt transformer is not advisable. The transformer may not be able to handle the load, leading to overheating, potential damage, or failure. It's essential to match or exceed the transformer's wattage rating to ensure safe and reliable operation.
How voltage is measured in potential transformer?
By connecting a voltmeter across the secondary terminals of the voltage/potential transformer. The transformer acts to reduce the voltage applied to its primary winding, while electrically-isolating the primary (usually high-voltage) circuit from the voltmeter.
Which type of transformer is use in gss?
Frgi transformer
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
