Voltage dips, also called sags, are brief reductions in AC

mains voltage, typically between half a cycle to a few seconds.

The best-known sources of voltage dips and interruptions are

listed below:

 The starting of a large load such as a motor or resistive

heater.

 Loose or defective wiring such as insufficiently tightened

box screws on mains conductors leading to the increase of

your system impedance, thus, making itself vulnerable to

the effect of current increase.

 Faults or short circuits draw excessive currents until the

protective devices such as a fuse or circuit breaker operates.

 Faults on distant circuit typically which can be automatically

switched and removed by reclosers. This type of event is

sometimes a series of voltage dips caused by continuous

operation of reclosers.

 Loads that have continuously varying power levels cause

voltage variations rather than an abrupt change.

Clearly from the above, voltage dips, interruptions, and

variations are everywhere and unavoidable.

Voltage dips and short interruptions are not always abrupt

because of the reaction time of rotating machines and

protection elements- the rotating machines will operate as

generators sending power into the network. Some equipment,

typically containing a power-fail detection circuit, is more

vulnerable to gradual variations than to abrupt change.

In any case, these voltage changes can degrade the

performance of electronic equipment in many different

ways: digital circuit upset, data-loss or distortion and so

on. Therefore, immunity testing for these types of events

should be performed to ensure your product's safe and

reliable operation.

In fact, in the scheme of international compliance, the

IEC 61000-4-11 compliance voltage dip test is a must

for all products having a rated input current not

exceeding 16A per phase.

The NoiseKen VDS-2002 Voltage Dip and Up Simulator,

uncompromising on and fully compliant with all the test

generator requirements in the standard including fast

rise and fall times, peak inrush current drive capability,

overshoot/undershoot and others, fulfills accurate

testing needs.
