Disadvantages of power Transformers depend on the type of transformer. Some disadvantages to three phase power transformers include greater cost of standby units and issues with repairs should one phase fail or be damaged.

What are the disadvantages of using the High power Objectives?
THE disadvantage of using high power objective is to
What is a disadvantage in using tidal energy?
its power output is not predictable
Is transformer is essential for rectifier?
no transformer is not necessary for rectification today most of power supplies have been made without using transformer in order to reduce weight and size of power supply.for example SMPS(switch mode poqwer supply)
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
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.
Why is it using low resistance coils in transformer minimize power loss?
To avoid voltage drop in the coil.
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
How much actual power does a 1KA transformer provide?
The kVA represents the power-handling capability of the transformer.So, if you were using a 1 kVA transformer at 110 volts, you could roughly estimate the maximum output to be 9 amps.
What you a disadvantage of using solar cells as an energy source?
The main disadvantage is that it is only works fully in direct sunlight, so you need another source of power, like battery power or a connection to the public power supply, when the sun goes in.
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
