Surge test (lightning test)
Introduction to Surge Test (Lightning Test)
Surge test (lightning test)
The purpose of surge test (lightning test) is to establish a common benchmark to evaluate the performance of equipment when subjected to high energy disturbance from power lines and interconnects. The task of laboratory test is to find out the response of EUT to surge voltage with certain harmful level generated by beginning or lightning when it works under the specified working state.
Inspection basis standard
IEC 61000-4-5/GB T 17626.5: Surge (shock) immunity test
Surge (impact) immunity test is to simulate the influence of lightning strike (indirect lightning) in nature and voltage change caused by large switch switching in power supply line and communication line. The surge test specifies two waveforms (1.2/50μs and communication wave 10/700 μs) with amplitudes of 0.5kV to 4kV. The energy is particularly large, and the impact on EUT may be destructive.
10/700 μs (commonly known as communication wave) is suitable for long-distance symmetrical communication ports, and 1.2/50μs is suitable for power line ports and other signal line ports.
detection technology
Tianhai detection Surge test system adopts 3C test's new test system CWS 600CT, with a test voltage range of 0.2 ~ 6kV. at the same time, it is also equipped with three-phase five-wire coupling decoupling networks SPN 3832T,AC380V 32A, Max. at the same time, it is equipped with communication line coupling decoupling network (data transmission rate up to 100Mbit/s) and non-shielded high-speed communication line surge coupling decoupling decoupling network (GDT coupling, it can realize 1 pair/2 pair/4 pair line to ground at the same time, and the data transmission rate is as high as 1000Mbit/s), which can meet the new version of Surge test.
Tianhai Testing Laboratory
Tianhai testing is set up and operated in accordance with the laboratory accreditation system specification ISO 17025. The testing instruments are made up of Germany's Rohde & Schwarz, Switzerland's EMTEST, YYOKOGAWA, Agilent, Tektronix and other world's top instrument manufacturers. The equipment is advanced and sophisticated, the site environment control is reliable, traceability is strong, the technical team is senior and efficient, and close cooperation with international authoritative organizations is maintained.
