C Type Impulse Current Test System with Crowbar

Application

The C type impulse current test systems with crowbar are sophisticatedly designed to generate impulse current of exponential shapes. The system can be designed in various ways for meeting customers’ requirements. The test system is applicable in testing of SPD, lightning protection components (MOV or air gap), lightning rod and aircraft device.

 

Standard

IEC 61643-1 2011, GB18802.1, GB/T 17626.5

GB/T 16927.2 ,YD/T 1235.1

 

Advantages and Features

(1)    Open structure to expand waveform

(2)    High peak current of 10/350s waveform with impulse capacitors of lowest capacitance

(3)    With crowbar switch to fulfill the perfect combination of the impulse voltage generator and impulse current generator

(4)    With the Yuntai control of 360 degrees of digital surveillance system

(5)    Automatic power-off earthing protection
