Ground resistance
testers are used for the design and testing of electrical grounding systems.
They are commonly used by power companies, industrial plants, CATV and telephone
companies and for antenna systems.
When good grounding systems are first
installed they have low earth ground resistance values. Conditions such as
corrosive soil with high moisture content, high salt content and high
temperatures eat away at the grounding rods and their connections. As a result
of these conditions the resistance value increases overtime causing poor
grounding. Poor grounding can be very dangerous and increases the risk of
equipment failure. Problems that arise are exposure to the risk of electric
shock, instrumentation errors, harmonic distortion issues, power factor problems
and a host of possible intermittent dilemmas.
To avoid such problems it
is highly recommended that all grounds and ground connections are checked
annually. Ground resistance testers are troubleshooting tools to help you
maintain uptime.
