FYMJ type capacitive voltage divider
Characteristics and Applications
1. AC capacitor voltage divider is mainly used for measuring AC high voltage, which can measure the effective value, peak value, instantaneous value of AC voltage, and is equipped with corresponding instruments. It can also be used for waveform recording and harmonic analysis.
When it is a non corona structure, it can improve measurement performance and also serve as an electrical coupling for measuring partial discharge and other non corona test circuits.
Main usage conditions and technical performance
1. Installation for indoor use, with an ambient air temperature of -25 to+40 ℃ and an altitude not exceeding 1000m (if exceeding 1000m is required, it can be specified in the ordering agreement).
2. The measurement error of peak or effective value of AC high voltage shall not exceed 2%.
3. The measurement error of harmonic voltage shall not exceed 10% of the actual harmonic value, or 1% of the fundamental amplitude, or the maximum of these two values.
4. The voltage divider error shall not exceed 1%.
5. For the performance of AC capacitor voltage dividers, please refer to the national standard JB/T8168-99
