Review of Bonding and Grounding Requirements
The Question What is the required bonding and grounding requirements to achieve compliance with the various electromagnetic compatibility (EMC) standards associated with electronic equipment? I received this question a few days ago and quickly realized that a quick and easy answer was not feasible since I virtually had no knowledge of what kind of equipment types were … [Read more...]
Preventing Impact of High-Altitude Electromagnetic Pulse on Power Transformers
Protection of a power system’s electrical equipment from a high-altitude (more than 30 km) nuclear explosion (HEMP) impact is a challenging issue, which until recently has not received proper attention. The fact is that HEMP does not affect people directly, while the electromagnetic pulse resulting from this explosion is a powerful devastating factor for the power grid’s … [Read more...]

Is Electric Equipment Grounding the Basic Protection Means Against HEMP?
Abstract The article discusses the differences between the electromagnetic pulses at lightning (LEMP) and at high altitude nuclear explosion (NEMP or HEMP). The article also shows that these differences do not allow to transfer LEMP experience on to NEMP. The author questions the effectiveness of grounding of electronic equipment as the main protection principle against … [Read more...]
Electrostatic Discharge (ESD) in Electro-Optic Devices
Many electronic components used in highly technological devices can be damaged or degraded by sudden electrostatic discharges, known by the term Electrostatic Discharge (ESD). Components such as transistors, diodes, laser diodes, electro-optical devices, and a variety of integrated circuits are all sensitive to electrostatic discharge. Many manufacturers are increasingly … [Read more...]
Review of MIL-STD-461 CS117 Lightning Induced Transients, Cables and Power Leads
Introduction Lightning may produce a spectacular display when viewed, but the associated electromagnetic effects (EME) has the potential (pun intended) to severely damage electrical and electronic circuits. MIL-STD-461G added a new test method to evaluate device tolerance for induced current on equipment cables or insulation breakdown from the effects of indirect lightning. … [Read more...]
