What is the pt transformer?
The abbreviation, 'PT', stands for 'potential transformer' (in Britain, the abbreviation is 'VT', and stands for 'voltage transformer'). This, together with a 'current transformer', falls into a category of transformer known as 'instrument transformers'. A 'PT' or 'VT' is used to reduce a high voltage to a level of voltage that can be safely read, remotely, by regular a.c. voltmeters or to provide inputs to high-voltage protection relays, while electrically- isolating the secondary circuit from the high-voltage primary circuit for the purpose of safety.
Why transformers are not excited with dc?
by using step-up transformer we can change the voltage in higher level
Why you tapchanger fix in transformer hv side?
A tap changer is used on the high voltage (HV) side of a transformer to adjust the voltage ratio and maintain a desired voltage level under varying load conditions. It allows for voltage regulation and compensates for voltage fluctuations in the power system. By changing the number of turns in the transformer winding, the tap changer can increase or decrease the voltage output, ensuring a stable and reliable power supply.
What is the breakdown voltages of 100KVA transformer bushing and arcing horns?
The question isn't correct, you have to define the voltage level not the power rating.
A transformer is a device used to?
Transformers change voltage and current from the primary side to the secondary side, while keeping the power in equal to the power out (minus losses). Any transformer will increase the voltage applied to the secondary (or low voltage side) to the primary (or higher voltage side).
What is the Use of distribution transformer?
A transmission transformer steps the voltage up to a very high value so electricity can travel long distances on transmission lines from the power plant to a city or area with low loss. A distribution transformer steps the high voltage back down to a level that can be used for local distribution and use by businesses and homes.
What is the purpose of voltage transformer?
A 'voltage transformer' (called a 'potential transformer' in North America) is classified as an 'instrument transformer', and is used to reduce the voltage of an electrical system to a lower, safe, level for the purposes of either operating a voltmeter or supplying a protection relay. At the same time, it electrically-isolates the meter or relay from the high-voltage system.
When step down transformer is activated what happens?
Step down transformer reduces high voltage of main power line and distribute it to desired level of voltage usable by residence or devices.
What is a electrical device that uses electromagnetism to change voltage from one level to another?
transformer.

Why does someone have to be careful around a high voltage transformer?
A high voltage transformer is a very dangerous piece of equipment. The voltage level is enough to electrocute a person if handled improperly. Only trained professionals should work with this type of equipment.
Why transformers are not excited with dc?
by using step-up transformer we can change the voltage in higher level
Can stabiliser used in place of transformer?
No, because stabiliser is used to stabilse the voltage level not for step up or step down more voltage.
What is an instrument transformer?
An 'instrument transformer' is a category of transformer used to supply measuring instruments or protective relays. There are two types of instrument transformer: a 'voltage transformer' (known as 'potential transformer' in North America), and a 'current transformer'. They are used with high-voltage systems, where it is hazardous to connect instruments directly to such systems.Voltage tranformers are used to reduce high-voltages down to a level that can be safely applied to voltmeters, or to the voltage-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instruments (and personnel) from the high-voltage supply.Current tranformersare used to reduce high-voltage currents down to a level that can be safely applied to ammeters, or to the current-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instrument (and personnel) from the high-voltage supply.
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.
Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
What is unit transformer?
UniT transformer are step up transformer which is connected to generating house & step up voltage from 11/15kV votlage to 220/400kV voltage level as requirement or line design parameter. It is just like transformer but connected to unit of the generating house that's why we called it unit transformers.
