Electrical Fast Transient
Electrical Fast Transient Testing Services in Canada
Electrical Fast Transient (EFT) are high frequency pulses that occurs because of the arcing on the power lines due connection or disconnection. This also occurs when relays, contactors, motors, or any other inductive load are turned off, then power distribution system experiences bursts of narrow high-frequency transients which can affect the performance of electronic equipment or might damage it.
IEC 61000-4-4 defines the test procedure to simulate these electrical fast transients and test the product to verify its susceptibility level. At INTL Inc. we have EFT generator that complies with IEC 61000-4-4 requirement which can perform EFT test with following parameters:
| EFT TEST - Electrical Fast Transient (EFT)/ Burst Immunity Test | |
|---|---|
| Output voltage | 0.2 ~ ±5kV |
| Frequency | 1kHz ~ 1200KHz ±10%, continuous adjustable |
| Polarity | Positive/negative/alternating |
| Pulse running time | 1 ~ 9999s, continuous adjustable |
| Discharge resistor | 330Ω |
| Internal resistance | 50Ω ±10% |
| Pulse rise time | 5ns ±30% |
| Pulse width | 50ns ±30% (50Ω load), 35 ns~150 ns (1kΩ load) |
| Number of pulses | 1 ~ 255, continuous adjustable |
| Burst period | 0.15 ~ 99.99s, continuous adjustable |
| Phase | 0 ~ 359°synchronous, asynchronous, automatic |
| Coupling/decoupling network | Single-phase three-line, 16A CDN Capacitive Clamp |
