EMC Test Equipment


Coupling / Decoupling Networks (CDN)

HAEFELY HIPOTRONICS offers various products to conform to IEC and EN standards. Both single phase AC mains and DC power ports must be tested. The use of coupling and decoupling characteristics are recommended, and based upon the European model for AC power lines. When testing according to ANSI and IEEE standards, much of the same requirements apply, but tests are based upon the American model for AC power lines.

Electrical Fast Transient (EFT) / Burst Test Systems

Industrial measurement and control equipment nearly always use conventional control units containing relays or other electro-mechanical switching devices. Fluorescent lamp ballast units, insufficiently suppressed motors (hair dryers, vacuum cleaners, drills, etc.) are found everywhere in the public power supply. All of these are primarily inductive loads which generate interference when switched on or off. EFT events, can cause microprocessor units to malfunction or reset, with corresponding disruption to normal operation.

Electrostatic Discharge Test Systems (ESD)

Electrostatic discharge (ESD) events occur when the static electric field between two objects exceeds the dielectric strength of the air between them. The discharge itself is a complex event involving a local transfer of charge at the point of discharge, electromagnetic near field coupling between the objects involved, induced current flow in the object receiving the discharge and radiated electromagnetic energy from the charged object as well as from the arc of the discharge.

Power Frequency Magnetic Field Test Systems

Power frequency magnetic fields are generated by AC current flowing in conductors. The normal 50/60Hz mains power cord is a good example, although currents with other frequencies may be present dependant on the application. Magnetic fields, may interfere with equipment operated in close proximity. Typical EUTs are monitors of all kinds.

Pulsed Magnetic Field Test Systems

Pulse Magnetic Fields are generated by lightning strokes on buildings and other metal structures including aerial masts, earth conductors and earth networks and by initial faults transients in low voltage, medium voltage and high voltage electrical systems.

Surge Combination Wave Test Systems

Surge events can be generated by lightning phenomena, switching transients or the activation of protection devices in the power distribution system. A surge itself is influenced by the propagation path taken so that impulses from the same event may have different forms depending upon where a measurement is taken. Combination Wave Generators (CWG) simulate a surge event in power lines close to or within buildings. Mostly the disturbances are tolerable because they are single events.

Surge Damped Oscillating Wave Test Systems

This phenomenon is representative of the switching of disconnectors in HV/MV open-air substations, and is particularly related to the switching of HV busbars, as well as to the background disturbance in industrial plants. The voltage front-wave has an evolution that includes reflections, due to the mismatching of the characteristic impedance of HV circuits involved. In this respect, the resulting transient voltage and current in HV busbars are characterized by a fundamental oscillation frequency that depends on the length of the circuit and on the propagation time.

Surge Immunity Test Systems

A surge itself is influenced by the propagation path taken so that impulses from the same event may have different forms depending upon where a measurement is taken. Combination Wave Generators (CWG) simulate a surge event in power lines close to or within buildings. Mostly the disturbances are tolerable because they are single events.

Surge Ring Wave Test Systems

Ring waves are used to simulate lightning or switching effects in domestic single or three phase supplies within an adequately protected building. The waveform has similar characteristics in both open and short circuit conditions. The ring wave is characterised as a bipolar damped oscillating wave.

Surge Telecom Wave Test Systems

Telecommunication networks and lines are often disposed to lightning strikes and their associated effects. All telecommunication systems linked with lines installed outdoors therefore require a reliable protection which needs to be tested.

Voltage Dips & Interrupts Test Systems

Voltage Dips and short Interruptions are caused by faults in the network or sudden large load changes. Voltage variations are caused by continuously varying loads connected to the network. AXOS 5 and AXOS 8 contain all the features expected from a top quality generator in a compact solution.
