voltage impulseelectrical insulationcable

General Description
This instrument measures technical indicators such as the structure and dielectric strength of the insulation of tested electrical instruments and devices. It is widely used for electrical equipment, instruments, transformers, power cords, energy meters, motors, power outlets, and cables. Dielectric strength tests provide methods for implementing national safety standards, thus highlighting their importance. They have become indispensable for research institutes, metrology and testing services, as well as the energy and electronics industries for the evaluation of electrical devices, electronic instruments, and household appliances.




Product Overview
This instrument features an elegant design, with the output voltage displayed on a digital tube for clear, intuitive, and precise use. Each parameter is adjusted via a small keypad, ensuring ease of use. The device incorporates advanced technology, optimized ergonomics, high accuracy, high reliability, and easy maintenance. This instrument uses an integrated design combining the control unit and the test voltage. Overcurrent protection is adjustable via a dial. The device is compact and lightweight. Known as a small AC/DC converter, it serves as basic testing equipment for users such as power plants, power distribution networks, and research institutes. It allows for dielectric strength testing at specified voltages on various electrical products, components, and insulating materials, evaluating the insulation level, identifying insulation defects, and measuring surge resistance.




Product Performance Characteristics
The instruments AC withstand voltage can be increased up to 3 kV AC, 0.33 A AC.
Portable device with an aluminum alloy chassis, offering excellent interference resistance, a compact structure, and a neat appearance. It effectively meets the needs of DC voltage withstand testing in environments where capacity requirements are low.
The instrument uses a digital dial for timing, effectively protecting the tested object from damage due to accidental failures. It also includes a time setting function for insulation and voltage resistance situations requiring precise timing.
The unique arrangement of the voltmeter and ammeter allows the operator to easily read the values ​​at a glance.

How to Use the Product
1. First, connect the test leads to the high-voltage tester output, and simultaneously connect the ground using bare copper wires with a minimum cross-section of 2.5 mm² for your safety. Then set the current, and then increase the voltage. The device will protect you against overcurrents.
2. Set the time using the dial (the selector allows setting in increments of 0 and 10 seconds, from right to left; for example, 10 seconds is displayed as 1 and 0). The maximum time is 99 seconds and must be set before the test. Do not press the setting button again after the test, otherwise the recorded time will be inaccurate. 3. After checking the wiring, connect the power supply and turn on the device. The power indicator (green) and the zero indicator (yellow) should light up. If the zero indicator does not light up, please reset the voltage regulator to zero.
4. Once the yellow indicator is lit, press the Start button. The output indicator (red) should light up. If it does not, press the Stop/Reset button, and then press the Start button again.
5. When the red indicator lights up, the voltage can begin to increase. Carefully monitor the voltage and current. When the rated test voltage is reached, press the timer button to start the stopwatch; the high voltage will automatically shut off after the programmed time. If the voltage and current suddenly drop to zero during the voltage increase, this indicates a failure in the tested product or insufficient current, triggering the protection circuit.
