What else can I help you with?
What kind of transformer is used to change the voltage of electric current in transmission lines before it enters houses in a neighborhood?
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
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
Which types of relay is use in power transformer?
A 'power transformer' is a category of transformer used within electricity transmission and primary distribution systems. Relays are widely used with power transformers to provide various types of protection that will act to disconnect the transformer in the event of a fault. Examples of these relays include Buchholz relays, earth-fault relays, and differential relays. Relays are also used to operate a power transformer's automatic tap-changing mechanism in order to compensate for changes in load.
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What will happen you f the rated power of transformer is changed?
You cannot 'change' the 'rated power' of a transformer except by changing the transformer for another one. You can, though, operate the transformer below its rated power or, for short periods of time, operate the transformer aboveits rated power.
What is meant by the term transform?
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 are the types of and uses for a transformer?
There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.
What is the role of electricity in the field of electronics?
The role of electricity in the field of electronics is to power electrical, electronic, and communication systems.
What is the purpose of a step-up transformer in electrical systems?
A step-up transformer is used in electrical systems to increase the voltage of the electricity being transmitted. This is done to reduce energy loss during long-distance transmission and to efficiently distribute power to areas that require higher voltage levels.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
What type of system usually consists of primary distribution lines or networks service transformer banks and secondary lines or networks?
Electric power systems
