A voltage divider is a specialized instrument for measuring high voltage, which can measure both DC high voltage and AC high voltage at power frequency. The entire device consists of two parts: a voltage divider and a measuring instrument. The voltage divider adopts a balanced equipotential shielding structure, and the entire device has the characteristics of accurate testing, good linearity, stable performance, reasonable structure, easy portability, simple operation, and intuitive display.
Instrument usage
Due to the lack of electrical isolation between the output of the voltage divider and the primary circuit, the voltage divider is mainly used for:
1. DC high voltage measurement of grounding system.
2. High voltage measurement of AC power frequency between the phase and ground of the grounding system.
Precautions
When using this device, there should be no debris around to avoid affecting the measurement accuracy.
2. Strictly maintain the operating distance to ensure safe operation.
3. Check the reliable connection of each part, especially the firm connection of the ground wire.
4. After the measurement is completed, enter the site only when the instrument measurement shows zero.
5. Overpressure use is strictly prohibited, and attention should be paid to surface cleanliness. When not in use, it should be stored in a cool and dry place.
Instrument characteristics
1) The voltage divider adopts high-precision resistor and capacitor combination components, special process sealing, dry sealing, and there is no oil leakage problem.
2) High input impedance: reduces test current, reduces power consumption, makes the product small and lightweight, stable performance, and high measurement accuracy.
3) The voltage divider, multi value kilovolt meter and dedicated cables are all placed in an aluminum alloy box, which is safe, reliable, easy to carry and transport.
4) A multi value voltmeter can directly read voltage values such as DC average, AC peak, true effective value, and peak value.
5) Organic composite insulation jacket is used for voltages above 150kV, which increases surface creepage distance and greatly reduces product height, making it more convenient to use and carry.
