南澳电气（武汉）有限公司 NAPR高精度 无局放分压器

NAPR Serieso PD Pulse Divider   NAPR高精度无局放分压器

产品简介 

NAPR系列无局放分压器又称耦合电容器，主要用于无局放测试系统测量交流电压或***局放电压信号，该系列分压器与普通分压器比较，有以下几个不同点：

1、都可以测量高压电压，但普通分压器不能测量无局放的高压电压；

2、普通分压器一般电容量较小（小于500pF），而NAPR系列电容量较大，一般在600-1000pF；

3、普通分压器为干式介质，体积比较小，重量比较轻，测量准确度一般优于NAPR系列；

4、普通分压器一般单独使用，NAPR系列分压器一般与无局放电源一起配合使用；
