- SOKEN Partial Discharge Tester DAC-PD-7
Magnet wires, printed circuit boards, connectors, semiconductors, small motors, electrostatic chucks and insulating materials
Since DAC-PD-7 contains the necessary circuits for PD testing, such as the test power supply, detector, coupling capacitor and calibrator, it can easily perform partial discharge tests with only the main unit. Partial discharge testing to judge the quality of magnet wires, printed circuit boards, connectors, semiconductors, small motors, electrostatic chucks and insulating materials can be easily performed. PD tests according to the international standard (IEC 60270, 60664-1. 61730-2) are available with the PC software.

PC Software
Voltage-Discharge Quantity Characteristic Test
AC test voltage is linearly increased to the max test voltage/PD Inception voltage, and automatically decreased.
PD inception and extinction voltages are determined according to a specified Threshold value (pC).
TIME-Discharge Quantity Characteristic Test
In this mode, two levels of voltage “V1” and “V2” are applied continuously.
“V1” is held for “T1” seconds and “V2” is held for “T2” seconds.
PD inception and extinction voltages are determined according to a specified Threshold value (pC).
If no discharge exceeding the criterion value occurs during the last 5 seconds of the holding time “T2”, it is judged as “PASS”, and if it occurs, it is judged as “FAIL”.
