CT Tangent Delta Testing

A sort of insulation test called   CT tangent delta testing   is used to quantify the dielectric loss in a current transformer's insulation.    The phase difference between voltage and current in insulation which is brought on by impurities or other flaws is measured by something called the tangent delta. A high tangent delta indicates deteriorated insulation, which could cause the current transformer to fail. w indind resistance testing  is a method of electrical testing used to gauge the DC resistance of the windings in a transformer or other electric machine.    An essential criterion for assessing the condition of the machinery and spotting possible issues before they become serious is the resistance of the windings. When the current and voltage are being measured, a high voltage is supplied to the insulation of the current transformer during  CT tangent delta testing . The ratio of the power lost through the insulation to the power delivered ...
