The DC high voltage generator under the UHV power can help many power workers conduct various power tests more conveniently.

In order to help you have a more comprehensive understanding of high-voltage testing, manufacturers of high-voltage testing equipment have organized explanations of commonly used terms for high-voltage testing equipment, hoping to be helpful to you.

1. Dielectric: also known as insulating material, abbreviated as insulation, is one of the most widely used materials in electrical engineering.

2. Insulation resistance: The resistance corresponding to the leakage current flowing through a dielectric after applying a DC voltage for a certain period of time.

3. Absorption ratio: The ratio of the insulation resistance value at 60 seconds to the insulation resistance value at 15 seconds in the same experiment.

4. Polarization index: The ratio of the insulation resistance value at 10 minutes to the insulation resistance value at 1 minute in the same experiment.

5. Dielectric loss: Under the action of an applied voltage, a portion of the electrical energy in the dielectric is converted into thermal energy, which is called dielectric loss.

6. Resistive current: A lossy medium can be represented by a parallel circuit of ideal capacitance and effective resistance. The current passing through a resistor is called resistance current.

7. Capacitive current: A lossy medium can be represented by a parallel circuit of an ideal capacitor and an effective resistor. The current passing through a capacitor is called capacitive current.

8. Full current: A lossy medium can be represented by a parallel circuit of ideal capacitance and effective resistance. The current passing through a capacitor is called the capacitor current, and the current passing through a resistor is called the phase sum of the resistor current, which is called the total current.

9. Dielectric loss: The angle between the total current in the medium and the capacitance current is called the dielectric loss angle.

10. Online measurement: Use specialized instruments to measure equipment under working voltage with the participation of personnel.

11. Online monitoring: Continuous or timed detection of device status is usually automatic without affecting device operation.

12. State based maintenance: from time-based maintenance to maintenance based on device operating status.

13. Preventive testing: In order to discover hidden dangers during equipment operation, prevent accidents or equipment damage, the inspection, testing or inspection of equipment also includes sampling tests of oil or gas samples.

14. Transformation ratio: The ratio of the number of turns between the high voltage side winding and the low voltage side winding of a transformer is called transformation ratio, which can be approximated by the ratio of the rated voltage of the high voltage side and the low voltage side.

15. Voltage current characteristic: The relationship between the voltage and current applied across electrical equipment or components is called voltage current characteristic.
