What is transformers job?
It depends on the type of transformer:transmission/distribution transformers step up or step down system voltagesisolation transformers electrically isolate two systems without affecting their voltagesmatching transformers are used in electronic circuits for impedance matchinginstrument transformers step down voltages (voltage transformers) or currents (current transformers) for measurement or protection applications
Why transformer is used before conected any semiconductor device?
because it is necessary to provide an over load protection ,surge protection,etc....hence an transformer is used...( particularly isolated transformers)
What is the RMU How you test the rmu?
a type of switchgear used to connect distribution transformers
Why desiel is used in transformers?
Transformers use transformer oil as an insulator and to conduct the heat away from the windings. The oil usually flows through a radiator in a closed circuit on high-power transformers.
Why current transformers are used after circuit breakers?
Current transformers are used to supply a ratio of the current flowing through the breaker to equipment such as protective relays and meters. If the CTs are used for protection, they are placed around a breaker to provide different, ideally overlapping, zones of protection.
Application of instrument transformer in power system?
Instrument transformers are used in power systems for measurement and protection purposes. Current transformers (CTs) are used to step down high currents to a measurable level for instruments and relays, while potential transformers (PTs) are used to step down high voltages. By providing accurate and isolated measurements of current and voltage, instrument transformers ensure the safety and reliability of the power system operations.
What is a transformer and its functions?
Voltage transformer or potential Transformers are used in conjunction with Current transformers for metering and protection purpose in HT and LT power system.
What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.

Distribution transformer vs power transformer?
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
What are the types of transformer?
There are a variety of types of transformers. These include autotransformers, polyphase transformers, leakage transformer, resonant transformers, as well as audio transformers.the decepticons are the bad guys, and the autobots are the good guys. bumblebee and optimis prime are autobots. megatron is a decepticon.
What is tie transformer?
It is a step down transformer which is used to supply the electrical power to the station transformers and the colony transformers
Why auto transformers are not used directly on dc circuits?
Transformers are not used on DC circuits because they rely on a varying magnetic field to transform power.
Which type of bone is used for protection?
The Flat Bone Is Used For Protection
What are the Relays in transformer?
There are many types of protection relays used in transformers depend upon its construction, size, use etc. They are 1. Buchholz relay for incipient faults like short ciruit, winding temparature protection, oil temparature protection, oil level protection, oil pressure protection, Pressure relief valve (for oil filled transformers) 2. Differential protection 3. Thermal Protection 4. Earth fault protection 5. Over current protection 6. Over excitation protection(where OLTC is used) etc

What are the applications of autotransformer?
Power transformers may be step-up or step-down. Distribution transformers are step-down. Isolation transformers are 1:1 ration transformers. Matching transformers are used in electronic circuits for impedence matching purposes. Instrument transformers are used to measure high-voltage voltages and currents or to operate protective systems.
