Correct Answer - Option 3 : Volt amperes

Current Transformer​:

• Current Transformer (CT) is used to measure the current of another circuit.
• CTs are used worldwide to monitor high-voltage lines across national power grids.
• Load on Current Transformer is called as a burden because Current Transformer secondary winding can’t be kept open, high voltage can do the insulation failure.
• So it is necessary to load the Current Transformer secondary winding continuously and ultimately it acts as a burden on the Current Transformer.
• The burden of Current Transformer can be specified as Volt-Ampere absorbed at a certain Power Factor.
