It steps down voltage by moving the iron core spacing. Mostly using on high current welding transformer. Easy to achieve changing output voltage
and does not need to use high power selector to switch voltage

What is the purpose of conducting sc and oc test of single phase transformer?
to determine the transformer characteristics...
Can you put a transformer on a 32 amp generate to drop the amps to 16 amps?
The purpose of a transformer is to transform one voltage to another voltage. This can be in the configuration of stepping up the voltage or stepping down the voltage . The load is what establishes what the current from the transformer is going to be.
How to configure 110 volts power supply to receive 220 volts?
A transformer is needed to convert 110 v to 220 v or vice versa. This type of transformer is commonly used in Europe for power tools in the building trade which run from a portable 110 v transformer with a centre-tapped earth for safety so that each side is only 55 v to earth. A 3 kVA transformer for this purpose costs about £80.
What is the purpose of OC and SC tests on single phase transformer?
Open circuit and short circuit tests are performed to determine transformer characteristics. In the case of a single phase transformer, SC tests would be performed to determine the impedance. The open circuit test will give excitation information (% excitation at specific voltages, often 90%, 100% and 110%, and no load losses).
Which type of transformer is use in gss?
Frgi 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 type of transformer has only a single winding?
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
What is the purpose of conducting sc and oc test of single phase transformer?
to determine the transformer characteristics...
What is the purpose of the transformer in the half-wave rectifier circuit?
what is the function of transformer in the half wave rectifier circuit
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 is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
What the purpose of the H1 terminal on a transformer?
The terminals H1 and H2 an a transformer indicate the primary side of the transformer. The secondary side is usually identified as X1 and X2.
What is the main purpose of a transformer?
step up transformer output gives the high voltage which is useful for transmiission of electricity
What is the purpose of transformer core?
yes core is usefull in transformer since it it increase the permeability for the flux (i..e,it offers less relucyance path thanj air ).Their by decresing the losses in the transformer.
What is purpose of ten delta test on transformer?
To ascertain the life of insulation, or effectiveness of the insulation (HV to LV, HV to earth and LV to earth) of the transformer
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 is the purpose of constant voltage transformer?
The term 'constant voltage transformer' is used to differentiate the operation of transformers that are intended to change voltage levels, from those intended to change current levels -a current transformer (CT), for example, is termed a 'constant current transformer'.
