Catalog Description

Megger DET14C

The  MGR-DET14C/DS is used to measure earth/ground resistance in multiple loop
installations without disconnecting the ground.
Designed with flat core ends, the  MGR-DET14C prevents dirt build-up, ensuring
measurement integrity and improved reliability over products with interlocking
teeth. Other enhancements include safety to CATIV 600V, a built-in filter
function for electrically noisy environments, time and date stamped stored
test results and ultra long battery life. .
Designed to quickly measure ground electrode resistance in applications where
this type of test method can be used and/or verify the integrity of ground
connections. The goal of ground resistance testing is to ensure that the
resistance ground electrode system is low enough to prevent or limit voltage
rises caused by fault current, electrical surges, lightning strikes, etc.
Clamp-on ground testers work in applications where there is a loop resistance
to measure with ground paths in the system (the more ground paths, the closer
to the actual resistance). A utility pole ground system is a classic example
of this type application.

Typical end users include:
Power utilities
Electrical contractors/electricians
Specialist grounding contractors
Electrical testing companies
Telecommunications companies
Mining companies
