Product Details

Introduction of high voltage tester:

     High voltage tester, also known as electrical insulation strength tester, or dielectric strength tester, also known as dielectric breakdown device, insulation strength tester, high voltage tester, high voltage breakdown device, voltage tester and so on. The test that a specified AC or DC high voltage is applied between the live part and the non-live part of the electrical appliance (generally the shell) to check the voltage withstand capacity of the insulation material of the electrical appliance is widely used in electronic components, household appliances, insulation materials, instruments and meters, lighting appliances, wire and cable, electric heating appliances and other industries.

Principle of high voltage tester:

A high voltage tester applies a voltage higher than normal operation to the insulator of the device under test for a specified period of time, and if the insulation is good enough, the voltage added to the above will only produce a small leakage current.

Parameters of high voltage tester:

Test voltage: 0 ~ 5KV AC ±5%

Leakage current: 0 ~ 2/20mA AC ±5%

Test time: 0 ~ 99 seconds; Manual control

Output power (Pmax):100VA

Transformer capacity: 500VA

Operation method of high voltage tester:

1. Plug in the power supply, turn on the power switch, and the power indicator is on;

2, select the power range, press the required current button;

3, select leakage current alarm value;

4, select the test time;

5. Connect the measured object to the measuring end, start the instrument, increase the test voltage to 1.06 times (or 1.1 times) of the rated working voltage of the measured object, switch the phase conversion switch, read the secondary reading respectively, and select the leakage current value of the large reading.

Notes for the use of high voltage tester:

(1) In long-term operation, the high voltage tester must not only withstand the effect of the rated working voltage, but also withstand the overvoltage effect that is higher than the rated working voltage for a short time during the operation (the overvoltage value may be several times higher than the rated working voltage value). Under the action of these voltages, the internal structure of the electrical insulation material will change. When the overvoltage strength reaches a certain value, it will cause the insulation breakdown of the material, the electrical appliance will not operate normally, and the operator may be electrocuted, endangering personal safety.

(2) The main test indicators of electrical safety of high voltage tester include AC/DC voltage resistance, insulation resistance, leakage current, grounding resistance, etc.

(3) The AC/DC voltage withstand test of the high voltage tester is used to test the electrical safety performance of the product in the actual working state, which is one of the important indicators of the electrical safety performance of the test equipment.
