Product introduction

NRP pulse divider is high-voltage measuring systems with under-damping and potential shielding. Mainly used for measuring for light wave, including light full wave,8/20us wave and other light waveform. It’s a special voltage divider for light waveform. Simple to operate, intuitive display, high precision, small in size, light in weight. It’s ideal high-voltage measuring equipment for Grid primary equipment testing(such as Zinc oxide lightning arrester waves steep testing, voltage transformer lighting full-wave testing, high-voltage switch lighting fill-wave testing, substation main transformer testing, high-voltage GIS testing,etc.), substation, high-voltage electrical equipment factory and high-voltage testing laboratory and other relative departments. 

Alternative name
NRP Series pulse impulse divider, pulse divider 
The Characteristics of the products

Adopting imported fill material and realizing highly stable, the inside adopt highly precision resistance and low tangent capacity, partial discharge. Small size, 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: The 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)

Product information
Five series dividers used for High voltage measurement, the difference are in uses object and major function:
1.FRC Series AC-DC voltage divider used for measuring the power frequency which the accuracy is less than 0.5%, AC high voltage under 300Hz, and DC high voltage which the accuracy is less than 0.5%. Widely used in national wide and city level power supply bureau, power plant, varies of electrical installation company and power maintenance unit of large power enterprise.
2.NR-PD Series Precision DC divider used for DC voltage precision measuring which the  accuracy demand is 0.2 %, 0.1% and 0.05 %.Such as the national wide and city level municipal pilot station, metering stations and research institutes .
3.NRPA Series Precision DC divider used for DC voltage precision measuring which the  accuracy demand is 0.2 %, 0.1% and 0.05 %, and the frequency is 30-300Hz. Applying to high-voltage cable dielectric loss testing by national cable manufacturers, and as a power frequency standard in provinces & municipal pilot station and electricity metering station, while measuring 30-300Hz AC high voltage.
4.NRV series high frequency divider measuring frequencies up to 1M-10M or more , the DC measurement accuracy is <0.1%, 10Hz-1MHz pulse pressure measurement accuracy is <1.0%, 1MHz above measurement accuracy < 3%. Suitable for analyzing the high-voltage circuit breakers, high voltage DC power supply , particle accelerator and  a variety of high-voltage high-frequency characteristics with an oscilloscope connection.
5.NRP series pulses divider use for measuring variety of standard light wave, the response time is less than 100ns.
6.Nanrui (NR) dividers naming rules as follows :
FRC-General divider series ( also known as SGB digital high voltage meter ) , mainly  measuring for frequency voltage , is inaccurate, just satisfy the general measurement requirements
NR-representative for Wuhan NANRUI Electric Co.;
P-is the first letter of precision, used for precision high voltage measurement
D-is DC, used for measuring DC voltage;
A-is AC, used to measuring AC voltage;
HF-is high and the frequency of the first letters used to measure high frequency voltage
P- is pulse, used for measuring the pulse voltage.

Ordering Information:
FRC series voltage divided into three kinds products based on different types of measurements
1.FRC capacitive divider (FRC said measuring AC also called AC voltage divider);
2.FRC RC divider (or called FRC AC and DC voltage divider that can measure AC and DC);
3.FRC resistor divider (or called FRC DC voltage divider for measuring DC)
If do not indicate the type, it defaults to AC and DC voltage divider
