1. Product overview
YTJC10-XX 10kV European-style plug-in type three-phase AC voltage sensor, based on capacitive voltage division + isolation structure, assembled on a standard European-style plug-in, small in size, light in weight, and easy to install. It is suitable for the measurement of the three-phase voltage and zero-sequence voltage of the power line in the ring net box (cabinet).
2. Features
● Capacitive voltage divider + isolation structure, high precision, good linearity, wide frequency band, small size, light weight, low power consumption
● There is no ferromagnetic saturation and ferromagnetic resonance, no risk of explosion
● Primary and secondary isolation, safe and reliable
● Low output voltage, no risk of secondary short circuit and large current
● Wide temperature range (-40℃～70℃)
● High insulation resistance (≥1000MΩ), does not affect line maintenance
● There is no interface layering problem, safe and reliable
● Strong load capacity (1MΩ), the cable length can reach 10 meters
● The casing is semi-conductive and grounded, with strong anti-interference ability
● Three-in-one cable output signal, easy wiring
