Pulse current injection compliance at first time of asking

The well-established procedure for checking compliance of a HEMP filter with the Mil-Std-188-125 specification is to inject a very high current pulse into the front end of the filter and monitor the residual current flowing through. Such Pulse Current Injection (PCI) testing is conducted independently of the filter manufacturer, by trusted test houses utilising specialist and often proprietary equipment. No test house in Europe offers such commer...

The impact of solar superstorms on engineering infrastructure

The Sun has always been benign towards the Earth, providing light and heat essential to the growth of civilisations. However, as our technology has advanced, so the Sun has become a threat too, with its constantly changing surface plasma creating magnetic storms. Paul Currie, Sales & Marketing Director, MPE, discusses the potential impact of these solar storms in more depth.

A practical response to the threat of IEMI

With the increasing use of electronics to control every aspect of modern life, from smart grids to driverless cars, Intentional ElectroMagnetic Interference (IEMI) is a growing threat. Various initiatives have been set-up to address the needs of specific market areas, and new standards are being worked on. William Turner, Senior Design Engineer, MPE, explains.

Safeguarding vital electronics

As acknowledged by the Shield Act in the US and the recent Electric Infrastructure Security Summits, the intense electromagnetic pulse (EMP) from a single nuclear weapon detonated between 25 and 500 miles above the Earth, possibly delivered by rogue nuclear states, could disable civil and commercial infrastructures as well as defence computer and communications networks.

Ground-breaking MIL-STD single-line 1200A HEMP filters from MPE avoid overheating from the paralleling of multiple lower current filters

The catastrophically destructive phenomenon of High-altitude ElectroMagnetic Pulse or HEMP can be caused either by the detonation of a nuclear missile high in the atmosphere or by space weather (solar flares and geomagnetic storms). MPE Ltd of Liverpool has pioneered electrical powerline filters for the protection of critical defence and national infrastructure assets from the effect of Nuclear ElectroMagnetic Pulse (NEMP) since the mid-1980s, wh...

Free-of-charge kits for trialling EMC protection on your military vehicles

Commercial-off-the-shelf or COTS filters from MPE Ltd for EMI/RFI suppression assist the compliance of equipment on military vehicles with DEF STAN 59-411 and MIL-STD-461. Although solutions vary in current rating (3A to 300A) or number of lines (standard 2-line or 1-8 multi-line configurations) to suit the precise application, the type of filter circuit configuration will often be very similar.

MPE TEMPEST filters prevent covert interrogation of conducted lines

The fact that electronic equipment such as computers and peripherals gives off electromagnetic emanations has long been a concern of the military, governments and commerce. Aimed at information security, filters for TEMPEST, often referred to as Transient ElectroMagnetic Pulse Emanation Standard, prevent eavesdropping on data radiated as signals from computers and peripherals via conducting lines (such as power, telephone or control line cables).

Nailing Common Misunderstandings About EMI Filters

Despite EMC issues now usually being considered at an early stage during the product design process, unexpected problems still occur. In some cases, a simple approach to EMC and filtering is found to work but, more often than not, a more in-depth analysis is required to address the relevant EMC design considerations and subsequently identify the EMC solution. Misunderstandings are prevalent when selecting EMI filters in the course of equipment de...
