NARP Series no PD Pulse Divider   NARP高精度無局放分壓器

產品簡介

NARP系列無局放分壓器又稱耦合電容器，主要用於無局放測試系統測量交流電壓或採集局放電壓信號，該系列分壓器與普通分壓器比較，有以下幾個不同點：

1、都可以測量高壓電壓，但普通分壓器不能測量無局放的高壓電壓；

2、普通分壓器一般電容量較小（小於500pF），而NARP系列電容量較大，一般在600-1000pF；

3、普通分壓器爲乾式介質，體積比較小，重量比較輕，測量準確度一般優於NARP系列；

4、普通分壓器一般單獨使用，NARP系列分壓器一般與無局放電源一起配合使用；

The Characteristics of the products

Adopting imported fill material and realizing highly stable, the inside adopt highly precision resistance and low tangent capacity,, light weight, ans easy to take.

 

The parameters of the products

1, Voltage level: AC: 50 kV-2000kV (Able to withstand the impact of rates 110% voltage peak value )

2, Responding time: <120ns (special requirements can be customized)

3, Impact of voltage waveform:

Lightning impulse full wave (referred as to lightning full-wave lightning) the main parameters is peak UP, pre-wave time T1, half peak time T2, the pre-wave of standard lightning full-wave time  is T1 = 1.2us

Half peak value time is T2 = 50us.

In order to obtain highly accurate testing data, it is recommended to adopt US Tektronix which more than 200M oscilloscope, while the other technical specifications should meet the high-voltage lightning wave measurement requirements.

4, Accuracy: AC: 3.0%

5, Insulating medium: Imported capacitor oil

6, Environmental conditions:

  Temperature: 0℃ ~ 45 ℃

  Humidity: <85% RH

7, Divided voltage ratio: 1000:1 or (according to customer requirements)

 

Power supply: AC110V/115V/120V/127V/220V/230V/240V optional

Input frequency: 50Hz/60Hz optional

Note: Our users can select the corresponding power which based on their local supply voltage and frequency, and we will confirm it before the delivery (or inform us that the goods will be used in which country advance)
