Surge Generator to New Height-Up to 20kV
There are more than 100 times thunder and lightning per second all over the world, and the transient
phenomena of power grid system switches happens frequently, which can not only cause equipment
malfunction, but also direct economic losses even casualties. Surge immunity test mainly simulates the
surge caused by power grid system switch and thunder and lightning (direct surge is not considered
here). When the equipment is working in the specified condition, exerting a certain harmful surge
voltage or current by surge generator to evaluate the surge immunity ability of them.
Types of Surge Generator
There are different kinds of test waveform such as 1.2/50us combination wave (suitable for the ports
which are connected to power lines and signal interconnect lines with short distance), 10/700us
combination wave (suitable for ports which are connected to the symmetrical communication lines),
railway surge signal waveform, resistance surge signal waveform and the test waveform regulated in
GR-1089-CORE (2/10us, 10/250us, 10/360us, 10/1000us) which can be used for different EUT. The
surge generator should accurately impose output signal onto the EUT, and make sure there are no
interference to other devices caused by the output signals.
The open-circuit voltage and short-circuit current waveform of 1.2/50us CWG (Combination Wave
Generator) are shown in Fig.1, and its main parameters contain front time and time to half-value, etc.

EVERFINE EMS61000-5H_15kV&20kV Surge Generator
can output combination waveform accurately and stably, it
can work stably without disturbing power grid and
surrounding equipment. It is especially suitable for outdoor
products, MIL-STD products and other non-standard
products.
EVERFINE has developed several types of surge generators for different applications, the surge
generators can be also customized according to clients' requirements. In this dazzling era which is full
of electrical equipment, the quality and safety of lighting products&equipment are particularly important.
And as the final censorship of production lines, equipment testing for QC/R&D is the most important and
reliable evidence.
