Megger DET14C - Earth Resistance Clamp Tester

The Megger DET14C induces a test current into earth systems and measures ground resistance in mulit-ground installations without the need to disconnect the ground. The Megger earth resistance clamp meter is a useful addition to the more traditional methods of earth resistance measurement that may require disconnection or additional stakes and can be used to measure ground resistance in multiple loop installations without disconnecting the earth. This technique offers fast earth testing in total safety with the added convenience of having a single point of measurement to read earth resistance. This Megger earth clamp tester also provides a True RMS current measurement facility up to 35 Amps, allowing measurement of earth currents and giving an indication of potential measurement problems and a useful overview of the general earth system dynamics.

The new Megger DET14C has been designed with flat core ends that ensure measurement integrity and offer improved reliabilty and long term accuracy. They are easy to clean and eliminate the risk of easily bent interlocking teeth often found in earth resistance clamp meters. A built-in filter function offers increased noise immunity. The elliptical shaped clamp design provides greater access to cables and earth straps particularly in confined locations. The clamp head accommodates cables up to 37mm in diameter and flat earth tapes that are up to 50mm wide. Making this earth resistance clamp tester ideal for use in power stations, substations and towers. The DET 14C clamp tester is particularly suitable for measuring earth resistance in various installations such as buildings, pylons and RF transmitter sites. It can also be used for the inspection and verification of lightening protection systems.

The unit is rugged, compact and has configurable audible alarms. Additional features include a configurable auto shutdown, data storage, self-calibration on power up and a calibration loop - all contained in a sturdy carry case.
