How do surge generators work

The SG61000-5 surge generator from LISUN offers a standard framework for assessing how well various equipment’s internal connections and power cords withstand high energy transient interference brought on by big capacity load switching and natural lightning surge induction. A surge generator is also known as a surge current/surge voltage generator, a combined surge voltage and current generator, a lightning surge immunity test, or a combination wave generator. This article will describe surge generators, their use, and their functionality in addition to briefly discussing LISUN as a seller of surge generators.

SG61000-5 Surge Generator
Combination wave/surge generators are frequently utilized as heavy, tabletop machines. It is vital to have grounded aircraft. In EM test situations, this is done to ensure the safe usage of a transient generator. To assess three-phase power line systems, larger coupling/decoupling networks are required. The system’s size is considerably increased as a result. To fulfill conducted immunity test criteria, combined wave/surge generators are required.

A combined wave generator is essentially an analog lightning surge wave generator designed for lighting companies that is highly reliable. One use for it is EMC Surge Immunity Testing. It may also be used to assess an overvoltage protector in an electrical circuit. It may also determine the impact current absorbing capability and jamming resistance of the connected electrical components. It offers a precise and superb basis for assessing each EUT port’s resistance to transient overvoltage disruptions. Surge wave generators’ intelligence, applicability, and dependability are their key advantages.

Surge Generator SG61000-5

All in all, the LISUN SG61000-5 surge generator offers a standard framework for assessing how well various equipment’s internal connections and power cords withstand high energy transient interference brought on by big capacity load switching and natural lightning surge induction. It completely complies with GB/T17626.5, EN61000-4-5, and IEC 61000-4-5 standards.

Efficient use of a surge generator
Surge comparison tests
are essential since they are the only method for detecting turn-to-turn insulation problems. These defects, which appear at voltages greater than the motor’s operating voltage, are precursors to catastrophic failures and motor shutdown. Using surge immunity test equipment, hard shorts and a variety of other issues in coils and windings are also discovered. Poor turn-to-turn insulation is the main reason for winding failures, including shorts to ground.

When a vulnerability occurs in an electrical closed loop, turn-to-turn arcs are created. Current enters the loop when the transformer is turned on. When this current is converted to heat, a hotspot is produced. The hotspot increases the heat by causing additional turns to short out. The whirling shorts finally stop on the ground.

How does a surge generator work?
The SG61000-5 recurrent surge generator provides a common framework for evaluating how well internal connections and power cords of varied devices survive high energy transient interference caused by huge capacity load switching and lightning surge induction.

Before turning on the generator, make sure the short-circuit connector is inserted into the safety circuit in order to utilize the equipment effectively. The plug can be altered or otherwise left in place to determine whether someone is using an external CDN. The generator’s mains cable should then be connected to one of the ground connectors on the back or front of the device, and it should be grounded properly.


Use the front or rear banana jacks on the UT to connect it to the CDN after plugging the UT supply cord into the line input on the back of the device to power it. Next, start the power and wait for the backup generators to start. Press the surge on/off button to turn the light off. Another option is to use a memory button to retrieve up to 32 programmed settings, or to use a dial-in variable mode to adjust the necessary parameters.

Press the charging voltage button and crank the dial to alter the voltage from 100 volts to 4.4 kV. By pushing this button, the phase angle may be altered. The number of trigger pulses in each test cycle for a single pulse can be changed using the number button. Moreover, before twisting the knob, the display must be blank.

By pushing the period button, the range of seconds is adjustable from 10 to 999. There are three possible outcomes: positivity, negative, or polar opposites. Right here, the coupling mode may be chosen. Once the settings are accurate, press the surge on/off button to turn on the light. Finally, activate the surge test by pressing the charging button.

Surge generator for sale
As LISUN Instruments Limited, LISUN was established in 2003. The LISUN quality system has been formally accredited in accordance with ISO9001:2015. It designs its goods in compliance with CIE, IEC, and other international or national standards since it is a CIE Member.

All products have a CE certification and have undergone independent lab verification. With background information like this and the significant market success of LISUN’s surge generator, it is clear that the best surge generators for sale are available at LISUN. Reviews of the product that the company has received attest to this very reality.

Do all surge generators operate using the same methodology?
No, the various types of surge generators have different functioning principles. Surge generators have changed throughout time, therefore their working principles differ. However, the preceding description of how LISUN’s surge generators work.

When operating a surge generator, what safety precautions should be taken?
A surge generator and isolation transformer should be used together since a surge test poses a significant voltage danger. A sudden, strong current pulse will be returned during the surge test. The system is protected while the sample is powered by the isolation transformer. The sample box is optional. It protects the operator in some way. The sample is placed into the sample box for the surge test. It’s noteworthy that LISUN may custom-make sample crates of various sizes for your samples.
