YTJNW10-32 10kV outdoor zero sequence voltage sensor
1. Product overview
YTJNW10-32 10kV outdoor zero-sequence voltage sensor is a 10kV three-phase AC voltage sensor with a capacitive voltage divider structure, which can be used to measure the three-phase voltage and zero-sequence voltage of ZW32 outdoor pole-mounted switches
Product naming rules:
2 . Features
This product is different from the traditional electromagnetic AC transformer. It adopts a capacitive voltage divider structure and has the characteristics of high precision, good linearity, wide frequency band, small size, light weight, high reliability, and high ground impedance (≥1000MΩ). It is widely used in the measurement of three-phase voltage and zero-sequence voltage in ZW32 outdoor pole-mounted switch for primary and secondary fusion of distribution network.
