Combinations Surge and EFT generators are typically benchtop, but heavy equipment. When doing testing on three phase power lines systems usually require much larger coupling/decoupling networks which substantially increase system size. EM test environments with ground planes with connections to earth are required to safely use transient generators.

Common Transient Tests

Combination Wave/Surge:

  • IEC/EN 61000-4-5 specifies two Combination Wave pulses: Open Circuit Voltage Short Circuit Current
  • A common combination wave test is the 1.2/50 & 8/20
  • Another test is the Telecom10/700 & 5/320 Combination Wave
  • The four standard test levels , excluded of EUT: 0.5, 1, 2, 4 kV (0.25, 0.5, 1, 2 kA)

Burst/EFT:

  • A typical burst has a single pulse rise time/duration of 5 ns/50 ns from a source impedance of 50 Ω
  • 15 ms bursts with a repetition rate of 5 kHz (or 100 kHz) are applied every 300 ms
  • The standard defines four basic test levels, all with repetition frequencies 5 or 100 kHz
  • The level voltage depends on equipment being tested:
  • Power ports: 0.5 , 1, 2, 4 kV
  • Signal and control ports: 0.25, 0.5, 1, 2 kV
