Application
The D type impulse current test systems are specially designed to generate impulse current of exponential shapes. The system can be designed in various ways for meeting customers’ requirements. The very user-friendly control unit can be expanded with a standard interface so that the tests can be controlled from a host computer.
The test object includes the below electrical apparatus:
SPD (surge protective device)
Varistor, GDT, TVS
Lightning rod
Other lightning protection device
Standard
IEC60060-1, IEC60060-2, IEC 61643-11, UL1449, NFC 17-102, GB18802.1, GB/T18802.21 and other national standards
