С & DF Комплект

It is high precision instrument for full automatically testing high voltage power device dielectric loss tangent and capacity on site in power plant, substation, etc. Frequency of Chief power supply is 45Hz and 55Hz, avoiding the interference from power frequency electric field, also suitable in the places where power is cut down and generator supplies power. The tester can test non-earthing or directly earthing high voltage electric equipment by straightly connecting and reverse connecting, as well as full-sealing CVT. features 1.Variable frequency technology ensures accurate testing in the condition of strong electric field interference. 2.Suitable for workshop, testing room, science and research institute to test tgδ of and capacity of high voltage electric equipments. 3.It tests tgδ of capacitor PT and C2, C2 capacity quantity of main capacity. 4.Internal is installed high voltage boosting transformer, and adopts zero closing switch, anti-lightning, and other safety measures. During the process of testing, output 0.5Kv-10Kv voltage. technique specification 1 high voltage output, 0.5 10kV,each transmission raise 500V,altogether 20 transimissions high voltage output cable, available for using when wire in on ground.
