Surge & Burst/EFT Generators

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.

The EMC Shop stocks most commong multi-test platforms for compliance testing to electrical transients. Rent or buy Surge and Burst/EFT Generators for individual tests or multifunction generators to complete an assortment of tests in a compact solution. Most systems can be easily upgraded to include additional tests as required.

Combination Wave/Surge Immunity Test Parameters

These are the most commonly used test specifications for evaluating electronics ability to surve surge/lightning transients.

  • 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)

 

  • 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

Electrically Fast Transients/Burst Immunity Test Parameters

These are the most commonly used test specifications for evaluating electronics ability to survive electrical irregularities.

  • 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
