Megger DET14C Earth Resistance Clamp Tester

Megger DET14C Earth Resistance Clamp Tester

The Megger DET14C Earth Resistance Clamp Tester is a highly sophisticated ground clamp meter that measure earth resistance and current flow using clamp technology. The Megger DET14 C represents a new generation of earth/ground clamp-on resistance tester and is the replacement of the Megger DET10C.

Megger DET14C Earth Resistance Clampmeter Key Features:

• Measures Ground Resistance from 0.05Ω to 1500Ω
• Measures True RMS Ground Leakage current from 0.5mA to 35A
• Elliptical clamp shape to improve access
• Jaw size up to 37mm on earth cables and 50mm for earth straps
• Automatic self calibration
• Auto ranging
• High and low alarms
• Memory storage of 256 records
• Backlit LCD display
• Indication of high noise content that may effect readings
• Hold function for difficult to reach installations
• Over current protected
• Warning of jaws open to ensure accuracy
• On-board storage of test results
• Calibration check loop for piece of mind
• Sturdy carry case contains complete kit
• Auto power off (configurable)
• First Earth Resistance Clamp Tester to have a CAT IV 600V safety rating

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.
