Inductive voltage transformer for GIS, H.GIS or PASS

H.GIS or PASS. and used in the power system for voltage measuring and protection.

The detail parameters as below:

1) Rated voltage: 132kV(the voltage ranges from 40.5~550kV).

2) The accuracy classes: 0.2, 0.5, 3P(GB, IEC,AS standards), or 0.15, 0.3(IEEE standards).

3) The maximum output:500VA (GB, IEC, AS standards), or ZZ(IEEEE standard)

4) The rated frequency: 50Hz or 60Hz.( the power grid frequency is…)

外壳由铝合金铸造而成,有SF6密度监测仪监测气体压力,并带有泄压装置,生产非常安全。绝缘材料为SF6气体,泄漏量不超过0.1%/年。局部放电小于5PC。

产品使用寿命很长,30年以上甚至40年,无需任何特殊维护。我们的技术已达到国际领先水平。
