Description
The Megger DET10C and 20C are highly
sophisticated instruments that measure earth resistance and current
flow using clamp technology. The instruments induce a test current
into the system without the need to disturb existing connections.
The Earth Resistance Clamp meter is a useful addition to the more
traditional methods of earth resistance measurement that may require
disconnection or additional stakes.
The DET10C and DET20C earth
resistance clamp meters are 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. The instruments also include a true RMS current
measurement facility to allow measurement of earth currents, giving
an indication of potential measurement problems and a useful
overview of the general earth system dynamics.
The units are rugged,
compact and have configurable audible alarms. They also feature auto
shutdown(configurable), data storage, self-calibration on power up
and are supplied with a calibration loop - all contained in a rugged
carry case. In addition, the DET20C has an USB download facility and
is compatible with Megger Download Manager software (supplied)
allowing further analysis and storage of data.
Application
The Earth Resistance Clamp meters
are particularly suitable for measuring earth resistance in various
installations such as buildings, pylons and RF transmitter sites. In
addition, they can be used for the inspection and verification of
lightening protection systems. |
