Clamps with elliptical apertures that can accommodate cables up to 39 mm diameter and flat earth tapes up to 50 mm wide make Megger's new DET14C and DET24C earth resistance clamp testers quick and easy to use, even with large conductors and in applications where access to conductors is restricted. In addition, these instruments are the first of their type to have a CATIV 600 V safety rating in line with EN61010, with 8 kV of transient isolation, and operator safety is further enhanced by a hazardous current warning that is operative on all test ranges.

• Elliptical clamp shape improves access
• Low maintenance flat jaw interface
• Measures ground resistance from 0.05 Ω to 1500 Ω
• Measures true RMS ground leakage current
• CAT IV 600 V safety rating

The SVERKER900 incorporates three current generators and four voltage generators, the amplitude, phase angle and frequency of which can be individually and accurately adjusted. In addition, the current and voltage generators can be connected in parallel or series to provide single-phase outputs of up to 105 A and 900 A. This means that, although the test set is principally designed for secondary testing of protection devices, in many applications it can also be used for primary testing.

To complement the current and voltage generators, the SVERKER900 features a large colour touchscreen that provides an intuitive user interface and a powerful internal processor that eliminates the need to use an external computer for most types of manual and semi-automatic testing.
