The test set comprises two distinct units: a working unit and a high-voltage (HV) unit. The working unit is equipped with all necessary operational and display components, allowing users to control the HV unit from a safe distance. The system is designed to adapt to various testing modes, utilizing either a rectifier or a resistance rod within the HV unit based on specific requirements. Additionally, the polarity of the test DC voltage can be conveniently reversed by rotating the rectifier rod in the HV unit. This flexibility ensures that the system can efficiently accommodate different testing conditions, providing reliable performance for various applications.
To enhance safety and accuracy, all components of the test set are engineered to be resistant to short circuits. They also include a current-compensated voltage measurement function, ensuring precise readings during testing. For the safe discharge of capacitive devices when operating in DC voltage mode, a discharge and earth rod specifically designed for the system is provided. This discharge functionality is crucial for preventing any residual charge from posing a safety hazard post-testing, thereby enhancing the overall reliability of the equipment during high-voltage testing procedures.
AC/DC HV Test Set Cable testing and diagnostics
There are rarely some other longer-lasting, extra sturdy and cost-effective testing gadgets than the two-piece high-voltage test gadgets from our series. They generate non-stop adjustable test voltages with mains frequency or optionally DC with positive or negative polarity. The display gadgets for current and voltage, the protection control unit and the regulating transformer for the voltage are incorporated inside operating unit.
