Lightning protection is a critical aspect of establishments that operate sensitive electrical equipment, especially in the broadcast industry. Tied to this first line of protection against lightning ...

In Episode 34 of EC&M Tech Talk, Electrical Trainer Randy Barnett covers three main points when it comes to earth resistance, also known as ground resistance. First, the National Electrical Code in ...

A properly designed and constructed ground electrode of any technical facility should function properly for many years. Its correct operation is primarily based on maintaining its assumed resistance ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

Neither a high resistance-grounded system nor an underground system can supply line-to-ground loads. If protection and monitoring equipment is connected from line to ground, then it must not threaten ...

Surface resistance and resistivity testers are essential tools for evaluating materials used in electrostatic discharge (ESD) control. By quantifying how surfaces resist or conduct electrical charge, ...
