What is surge immunity test? Lightning strike and switching operation of power distribution system will produce transient overvoltage, which will cause monopolar transient interference to electrical and electronic equipment. The ability of electrical and electronic equipment to withstand such electromagnetic interference without reducing the operating performance is called surge immunity. The surg...
Surges are a nightmare for any circuit designer and a very important aspect of electronics. These spikes are frequently referred to as “impulses,” which are high voltages that last for a brief period of time and are typically measured in the kV range. Lightning is an example of a natural phenomenon that creates surges. Surges are characterized by a high or low fall time in voltage foll...
Since the birth of the world’s first semiconductor light emitting diode in the 1960s, LED lighting has been known as the light of hope in the history of human lighting because of its long life, energy saving, rich colors, safety and environmental protection. LED is also known as light emitting diode, is a solid-state semiconductor device that converts electrical energy into visible light, ...
What is the Surge Test? The surge (impact) immunity test is to simulate the effects of lightning strikes (indirect lightning) in nature and voltage changes caused by large-scale switch switching in power supply lines on power supply lines and communication lines. The surge test specifies two waveforms (1.2/50 μs and 10/700 μs for communication waves), with amplitudes ranging from 0.5kV to 4kV, w...
What is EMC test: EMC refers to the ability of equipment or system to operate in accordance with the requirements in its electromagnetic environment without causing unbearable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, the electromagnetic disturbance generated by the equipment to the environment during normal operat...
Testing purposes? GB/T 17626.5-2008 / IEC 6100-4-5:2005 standards specify the immunity requirements of equipment to unipolar surges (impacts) caused by switching and lightning transient overvoltages. The purpose of this part is to establish a common benchmark for evaluating the performance of electrical and electronic equipment when subjected to surges (shocks). The test methods specified in thi...
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 genera...
Working Principle of Surge Generator SG 61000-5 The SG 61000-5 standard is based on immunity criteria. It defines the test techniques as well as the standard testing levels for equipment against unidirectional surges caused by switching and lightning transients. The degrees of electrical and electronic equipment testing vary depending on the environment and installation conditions. Establishing a ...
Additionally known as the lightning surge immunity test, combination wave generator, surge current/surge voltage generator, and combined surge voltage and current generator, the LISUN SG61000-5 completely automatic surge generator has various names. It offers a uniform platform for testing how well different types of equipment’s internal connectors and power cables hold up to high-energy t...
Lightning is a kind of discharge phenomenon between thunder clouds or between thunder clouds and the earth in nature It is characterized by high voltage, large current and short energy release time, which is very harmful Lightning will cause large-scale power cuts in the power system, large-scale burning of forests, destruction of buildings, explosion and fire in oil depots, paralysis of communica...
Over voltages are a common source of damage in industrial electronic systems. It has been discovered as technology has advanced. Air discharges can also cause over voltages in addition to the equipment’s switching operations. The transfer impedance may be high or low depending on the location of the interference source. The transmission impedance will be low if there is interference in the s...
After in-depth study on the three main forms of direct lightning strike, conducted lightning strike and induced lightning strike, people have established the theory of lightning induction and high-voltage counterattack, and defined the transmission law of high-voltage lightning wave on metal wire On this basis, gap series fuse arrester, gapless zinc oxide arrester and transient overvoltage surge s...
