General Information
Description
DP 801 Series high voltage DC Withstand test sets, provide DC high voltage source up to 60Kv for checking the quality of power cables, insulators, transformers, motors, switchgear, capacitors and arresters
Based on PWM technology and IGBT components, DP 801 Series is APT new-generation DC Hipot Tester higher reliability, small size and light weight, its control module and Hv tank can be put into one suitcase
Really portable design, suitable jobsite work. Such as acceptable and preventive test
DP 801 series have three models, DP801/2 with 2mA leakage current, DP801/3 with 3mA leakage current,
DP801/5 with 5mA leakage current
Detailed Information
Special HV Output Buttons and Indicators design:
Red and Green button and their indicators design on the control panel, ensure its HV output could be realized only HV output is connected and all protections in good condition
Red or Green indicator prompts its diffident status
Such as design, make sure the operator and test equipment in safety
Product Features:
□Based on PWM technology and IGBT components:
□Feedback circuit performed to reduce Ripple ratio;
□Stepless adjustment for voltage output, all range;
□Digital meters for Voltage and Current display;
□Air-insulated, Epoxy resin cylinder;
□Simple connections; simple operation;
□Yellow Button & Indicator: With 0.75UDC1mAfunction button, zinc oxide arrester can be measured;
□Red Button & Indicator: HV connected or Disconnected, Safety design;
□Green Button & Indicator: the indicator is lighted, power supply is on and HV output is disconnected; Safety design;
□Power Switch & Indicator: the switch could be used for emergency stop;

APT
2020-05-07 10:50:31DC Hipot is available by AC rectification and filtering. Therefore, some AC elements must be remained at its DC Hipot output. The ripple factor is defined to DC Hipot quality. The ripple factor=the ripple value/the output value. For APT Power DC Hipot test set, their ripple factor ≤0.5%. and its ripple voltage will be ≤ ±0.5KV for 100KV DC Hipot.
