Features
Built-in / External CDN:
Integrated or compatible coupling/decoupling networks (CDN) enable safe injection of surge pulses into single-phase or three-phase power lines as well as data and communication lines, while preventing surge feedback from damaging the power supply network.
Intelligent Control:
Equipped with a touchscreen interface, the system allows automated programming of test parameters (such as voltage, phase, polarity, and repetition rate). It can also automatically generate test reports upon completion.
Comprehensive Safety Mechanisms:
Features overload protection, emergency stop interfaces, automatic discharge functions, and safety interlock systems to ensure operator safety during high-voltage testing.
Maintenance Information
Cooling and Ventilation:
Regularly clean the fans and ventilation filter screens to prevent dust blockage, which may cause internal overheating of the equipment.
High-Voltage Cables:
Inspect high-voltage test cables for aging or damage to the insulation layer. This helps prevent high-voltage arcing and leakage current.
Fuse Replacement:
The power input terminal on the instrument panel is typically equipped with a fuse. If the device shows no response, disconnect the power supply and check whether the fuse is blown. When replacing, always use the manufacturer-specified type and rating.
Internal Maintenance Warning:
Since the test system contains high-voltage energy storage capacitors, do not open the enclosure yourself. Any internal hardware repair or safe discharge operations must be handled by qualified professional technicians.
