IMMUNITY TO HIGH-ENERGY SURGE VOLTAGE

The purpose of the test is to show the immunity of devices to high-energy surge voltage. Electronic products are tested for Surge immunity to insure their continued reliable operation if subjected to realistic levels of surge voltages. The European Union’s EMC Directive currently mandates Surge testing for some products; however, it is expected that virtually all electrical and electronic products will have to be tested for Surge immunity in the near future as a condition for obtaining the CE Mark before shipping products to a member state of the European Union.TTests are performed in accordance with Basic EMC Standards: IEN 50130 and EN 61000-4-5.

IMMUNITY TO THE DISCHARGE OF ELECTROSTATIC ELECTRICITY

Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials caused by direct contact or induced by an electrostatic field the term is usually used in the electronicsand other industries to describe momentary unwanted currents that may cause damage to electronic equipment. The purpose of the test is to show that devices have the immunity to the electrostatic discharge. Tests are made according to EN 61000-4-2.

RADIATED, RADIO-FREQUENCY, ELECTROMAGNETIC FIELD IMMUNITY TEST

A GTEM or Gigahertz Transverse ElectroMagnetic cell is a precision electromagnetic compatibility (EMC) test instrument, primarily intended for use in an EMC radiated-immunity and radiated-emissions test facility. Its unique characteristics allow for the performance of fast and efficient EMC radiated tests at a convenient location, without interference from the ambient electromagnetic environment. Tests are made according to EN 50130-4 and EN 61000-4-3.

MAGNETIC FIELD IMMUNITY

Magnetic Field Immunity tests check the behavior of products when exposed to powerline- frequency magnetic fields, such as from poorly- routed power wiring. Because these fields are continuous, and out of the user's control, immunity standards require the product to meet special requirements, it must operate normally, without any user intervention. Tests are made according to EN 50130-4 and EN 61000-4-8.

IMMUNITY TEST FOR FAST TRANSCIENT BURST

Testing for fast transient bursts is most important, not only for reliability but because fast transient immunity testing is called up by a number of other standards listed under European Directives. The repititive fast transient test is a test with bursts consisting of a number of fast transients, coupled into power supply, control, signal and earth ports of electrical and electronic equipment. Significant for the test are the high amplitude, the short rise time, the high repetition rate, and how the low energy of the transients. The test is intended to demonstrate the immunity of electrical and electronic equipment when subjected to types of transient disturbances such as those originating from switching transients (interuption of inductive loads , relay contact bounce). The tests are made according to EN 50130-4 and EN 61000-4-4.

IMMUNITY TO CONDUCTED DISTURBANCES INDUCED BY RADIO-FREQUENCY FIELDS

The source of disturbances is basically an electromagnetic field, coming from intended RF transmitters, that may act on the whole length of cables connected to installed equipment. The dimensions of the disturbed equipment, mostly a subpart of a larger system, are assumed to be small compared with the wavelengths involved. The in-going and outgoing leads behave as passive receiving antenna networks because of their length, which can be several wavelengths. The test generator includes all equipment and components for supplying the input port of each coupling device with the disturbing signal level at the required point. The tests are made according to the following European Standards EN 50130-4 and EN 61000-4-6.

VOLTAGE DIPS, SHORT INTERRUPTIONS AND VOLTAGE VARIATIONS IMMUNITY TESTS

Dips and interrupts can occur on the AC power mains as a result of a fault in the distribution system such as an open circuit breaker or a sudden large load being turned on in the immediate vicinity. A power distribution system fault can cause a switch in the distribution grid to open and close a number of times, resulting in multiple interrupts to electrical and electronic equipment. Electronic products are tested for immunity to dips and interrupts to insure their continued reliable operation if subjected to dips and/or interrupts on the AC power mains. The European Union’s EMC Directive mandates dips and interrupts testing for virtually all electrical and electronic products as a condition for obtaining the CE Mark before shipping products to member states of the European Union. Tests are made according to EN 50130-4 and EN 61000-4-11.
