Simplify Ground Testing with the Megger DET3TC

Megger_DET3TCProper grounding provides many varied benefits to both people and facilities. It lessens the chance of injury due to faulty installation, reduces the likelihood of damage from lightning strikes and induced voltages, improves the performance of computer, communication and other sensitive equipment and protects against static electricity from friction. Over time, ground systems can degrade or become ineffective.

Corrosion and weather influences exert mechanical strain on ground rods and cause metallic corrosion. Catastrophic events like lightning strikes or large fault currents can cause instant degradation. In addition, facility expansion can create different ground system needs.

The risks from ground system deterioration include potentially deadly electrical shock situations, plant-wide equipment damage, disruption in the performance of sensitive equipment and heat build-up on a single piece of electrical equipment.

The maintenance of an adequate low resistance ground connection is essential to both the protection and performance of any electrical system. Ground testing should be performed both upon installation, to meet design specification, and periodically thereafter in order to maintain service.

The Megger DET3TC Digital Ground Tester can perform bonding tests (using an ac signal), to determine that adequate connection has been made from equipment to the grounding system. Furthermore, the addition of a built-in current clamp capability enables the testing of attached grounds (ART) without lifting the utility connection.

Applications to systems that have been connected to the utility feed are simplified with model Megger DET3TC Digital Ground Tester, where a built-in clamp input permits individual components of an expanded system to be separately measured without extra calculations.

Grounding electrodes from simple to complex systems can be tested with the Megger DET3TC Digital Ground Tester, including:

• Primary and secondary electrical grounding systems

• Utility pole grounds

• Lightning protection systems

• Residential grounds

• Machinery safety grounds

•  Computer and communication system grounds

• EMI/RFI system grounds

• Antenna and pedestal grounds

• CATV system grounds
