What are the Advantages of Instrument Transformers?
Advantages of Instrument Transformers:
The following are the advantages of
instrument transformers over the shunts and multipliers etc.
1. The readings of instrument
transformers do not depend upon their constants such as resistance, capacitance
and inductance etc.
2. The secondary winding of CT
&VT shows a current and voltage respectively of such a low value which falls
in the collection of measuring instrument can be done easily.
3. With the use of instrument
transformer or transformer Lamination Manufacturer the measuring circuit is isolated from power circuit.
4. With the standardization of CT
& PT's secondary winding it is possible to standardize instrument around
the rating and so it becomes easy for manufacture to have a great reduction in
costs of instrument transformer.
