High voltage Capacitive voltage divider is used to measure AC high voltage,because of its high voltage strength and difficult breakdown compared with common resistance divider. However, because the response time of the frequency response effect is larger than that of the resistive divider, it is less used in the measurement of impulse voltage than that of the resistive divider, and the resistive voltage divider is often used to measure the impulse voltage. Series resonance will be used in high voltage AC withstand voltage test, then High Voltage Capacitive Voltage Divider will be used in series resonance, which will produce high voltage after resonance with reactor,and the high voltage AC dielectric test can be carried out on the high voltage equipment.
Capacitance divider application
High Voltage Capacitive Voltage Divider as one of the high voltage measurement system is suitable for pulse high voltage, lightning high voltage and power frequency high voltage measurement. It is a substitute for high voltage electrostatic voltmeter equipment. High Voltage Capacitive Voltage Divideris widely used in high voltage measurement in power plants, substations, high voltage electrical equipment manufacturers and high voltage laboratories.
Coupling capacitors features
1.High Voltage Capacitive Voltage Divideris directly connected with high voltage measuring end, which can realize long distance clear reading, safe and convenient to use.
2.Small size, light weight, easy to carry, suitable for site inspection.
3.The input impedance of the high voltage measuring system of the capacitor divider is high and the linearity is good. The special shielding technology is adopted to reduce the influence of the high voltage on the indication value and to realize the high stability and high linearity.
4.The High Voltage Capacitive Voltage Divider uses imported filling materials to make the structure smaller, lighter weight, higher reliability and lower internal partial discharge. Small size, light weight, easy to carry, for the site inspection work to bring great convenience.
