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 ...

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 ...

AEMC’s rugged, digital ground resistance tester model 6470 performs grounding resistance, earth coupling measurement, soil resistivity and bonding tests. AEMC’s rugged, digital ground resistance ...

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 ...

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 ...

Earth/ground digital clamp-on resistance testers from Megger are easy to use, versatile and safe. Testing with the DET14C and DET24C can help prevent a rise in voltage caused by fault current, surges ...

With today's focus on higher speeds and wider bandwidths, it often is helpful to revisit basic yet critical design considerations. As a refresher topic on grounding techniques, we present this update ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

Norristown, PA. Megger has enhanced its DET24C earth/ground digital clamp-on resistance tester to include Bluetooth. This upgrade allows users to download stored test results instantly to a PC instead ...
