DC Hipot Testers DPW Series DC Hipot Testers DPC series Udey Test Kits
DC Hipot Testers DPW series : These portable testers have been designed to be used in testing high voltage equipment in power engineering. Routine testing of the insulation and leakage is a necessary requirement for surge arresters, cable breakdown testing, capacitor charging and other laboratory use.
Model : DPW-60-5 DPW-80-5 DPW-120-5 DPW-160-2 DPW-200-5
Machine Feature
- Switched-mode technology utilizing pulse width modulation to control the output voltage accurately.
? Voltage divider is an integral part of the tester with an surge limiting resistor.
? Tester delivered in two sections: Control and HV unit. Each packed in a flight case for easy transportation.
? Testers of over 200kV voltage, HV unit has adjustable legs to increase the equipment?s stability.
? Digital kilo voltmeter and ?A/mA meters display the test voltage and leakage current.
? Zero start up. Audible alarm and LEDs for breakdown and over voltage occurrences.
? Small dimension. Low weight. Carried conveniently.
? Discharge pole with limiting current impedance.
