The current probe is designed for measurements of AC currents up to 1000 A with a 1000:1 step-down ratio. The probe offers excellent accuracy (0.3% error at full range) and small phase shift (0.7° at full range) so it can be used for metering of power, energy and power quality applications. Such high performance is achieved because the magnetic cores are made from high-permeability FeNi alloy. The rated terminating resistance (burden) of 1 Ω must be provided by the instrument connecting to MCC1010 and MVC1010. The output terminals are protected with a voltage limiting circuit ensuring a safe-to-touch voltage under all rated conditions.

MCC1010 and MVC1010 are rated to CATIV 600 V, according the international standard IEC 61010.

CAT IV 600 V current measurement to 1000 A AC

1 mA/1 A sensitivity with rated burden of 1 Ω

Large jaws for cables up to 52 mm

Overvoltage protection of the output terminals

Suitable for leakage currents

The DET14C and DET24C represent a new generation of earth/ground clamp-on resistance testers. These instruments induce a test current into earth systems and measure ground resistance in multi ground installations without needing to disconnect the ground. They offer market leading access,advanced features, simple operation and CAT IV 600 V safety protection.

Designed with flat core ends they prevent dirt build up,ensuring measurement integrity and improved reliability over products with interlocking teeth. Other enhancements over current generation products include improved accuracy and up to 300% increase in battery life. In electrically noisy environments the built-in filter function offers increased noise immunity.

The Megger® DET2/3 automatic earth (ground) test instrument is robust, compact and designed to measure earth Electrode Resistance and Soil Resistivity. It provides a full range of test methods and excels at the four terminal method of measurement, which eliminates the resistance of the current circuit from the measurement. The DET2/3 is a reliable instrument for use on large or more complex earth systems, which include communications earth systems and difficult test environments.

• Highest accuracy for earth (ground) electrode grid and soil resistivity tests
• Diagnostic trace display - live trace of its measurements
• Automatic test frequency selection, with filters and high current features
• Data storage - Test result data can be downloaded directly through a USB flash drive or straight to a Windows  PC running PowerDB™ software
