YD series Test Transformer is applied to test the insulation ability of electric power equipments and insulation materials at power frequency high voltage.

Production Description:

Introduction: YD series Test Transformer is applied to test the insulation ability of electric power equipments and insulation materials at power frequency high voltage. The insulation test result of the tester is go or not go. Also the YD series Test Transformer is a universal power source in HV test. The maximum output voltage and capacity could be customized according the requirements of custom. YD series Test Transformer is consists of single HV transformer and main control box. There are two kinds of HV transformer according to the insulation materials of the HV transformer. They are dry HV transformer and oil HV transformer. For the dry HV transformer the insulation material is epoxy resin. For oil HV transformer the insulation material is insulation oil. The dry HV transformer has a smaller size and less weight than oil HV transformer. But the maximum output voltage is less than 100kv for dry HV transformer. The functions of the main control box are voltage output regulation, protection in emergency and voltage/current value indication Technical Specifications 1) power supply: AC220V 50Hz/60Hz for transformers which the capacity less than 10kva AC380V 50Hz/60Hz for transformers which the capacity more than 10kva 2) HV transformer mode: single phase 3) Maximum output voltage: 50kv/100kv/150kv/200kv/250kv optional 4) Output capacity: 3kva/5kva/10kva/20kva/30kva/50kva/100kva/150kva/200kva optional 5) Voltage read mode: analog or digital, direct HV voltage reading form voltmeter 6) Current read mode: analog or digital, direct LV circuit current reading from amp meter 7) Protection mode: LV circuit over current protection 8) Voltage adjust mode: manual regulation 9) Rated frequency: 50Hz/60Hz 10) Automatic zero position lock unit to avoid wrong operation in HV output 11) Work temperature: 0~50degree 12) Work humidity: 80%
