We AJIT ELECTRONICS CORPORATION are Manufacturers, Exporters & Leading Suppliers of Oil Tan Delta Tester Loacated in Dombivli, Thane, Mumbai, India.
The current through the capacitor will not lead exactly 90 deg. From the voltage across it. This extent of deviation in the phase is measured with an ultra sensitive phase detector comprising of solid state components only. The stress voltage at which the measurements are to be made, can be set as desired. Power source is continuously variable up to 600 V AC which gives a maximum stress voltage of 300 / v / mm in our Three Terminal Oil Cell. However, if tests are to be carried out at higher stress voltage then the high rating power source can be supplied at extra cost. The stress voltage in normal test should be above 200 V/mm. as per IS recommendation.
