The MTD20KWR digital earth tester allows for the measurement of Earth Resistances and Soil Specific Resistivity, and also the spurious voltages caused by parasitic voltages present in the soil.

This equipment is suitable for fast and easy measurement of the grounding resistance in house and industrial buildings, hospital installations, lightning rods, antennas, substations, etc. Soil resistivity measurement allows for soil stratification in order to optimize the most complex grounding systems engineering.

Its state-of-the-art system of active and passive filters provides it with high immunity to electric interferences, making it possible to obtain reliable measurements even in the presence of spurious voltages, such as the ones that can be found in some urban areas and near primary substations.

A 1,470 Hz internal generator injects alternated current on the soil through an auxiliary rod. The voltage generated over the earth resistance is measured by the apparatus, and the resistance value is evaluated. The test current is automatically regulated.It has abnormalities indications on the display which advises the operator when the generated current is not enough to carry out reliable measurements.Because of its wide range of measurement (from 0.01 Ω up to 20 kΩ), this equipment allows for reliable testing in all kinds of soils, including those that offer very high resistivity.

This earth tester is supplied with a rechargeable internal battery. The smart charger is microprocessor-controlled, and can be powered from a 12 V car battery (or a similar one).

It has a sturdy, easy and safe to carry cabinet, with IP65 protection level (closed lid). It is suitable to work under adverse geographical and environmental conditions, with extreme temperatures in cold or tropical regions and in high mountain areas, showing a reliable performance in the field.

The MI-15KVe High-Voltage insulation tester is a truly portable device that allows the measurement of insulation resistances using test voltages up to 15kV. 

It employs a state-of-the-art technology for the safe measurements of insulation resistances up to 3,000,000 MW with four test voltages: 1 kV - 5 kV - 10 kV and 15 kV. 

Readings are performed through an easy-toread analogue indicator, having a broad scale.

Due to its reduced size and weight, its power autonomy and mechanical strength, this insulation tester is suitable for working out in the field, under severe weather conditions. It is powered with a rechargeable battery, with a charger for 110 V/220 V. In order to protect the equipment, the cabinet is water and dust resistant. Protection grade is IP54, and the insulation tester is supplied with a complete kit of high voltage test leads.

The MI-20KVe High-Voltage insulation tester is a truly portable device that allows the measurement of insulation resistances using test voltages up to 20 kV.

The Megabras MD-5060x is a smart, microprocessor-controlled, 5kV insulation tester and analyzer. Besides the conventional measurement of insulation resistances up to 5 TW, its advanced features allow to automatically measure both the Polarization Index and Dielectric Absorption Index, thus significantly simplifying testing of transformers.

This insulation tester is a portable, battery-powered equipment. Test voltage may be chosen from 500V to 5 kV in 100 dddV increments. Due to its measurement principle (actual voltage and current readings) the accuracy of resistance measurement is not affected by any test voltage error. Nevertheless, the High-Voltage generator is electronically stabilized with a better than 2% accuracy in open-circuit condition and for any normal operation battery voltage.

The MD-5060x is powered using a rechargeable battery and has an automatic charger that may be connected to 100 - 240V mains supply. The cabinet is strong and lightweight, easy to carry, impact-resistant and suitable to be used under severe weather conditions. Thus the megohmmeter supplies very reliable and accurate measurements both in laboratory and out in the field.

CRM 100B directly measures micro-ohm values at 100 Amps DC under live switchyard conditions.

CRM 100B is specially designed to reliably measure contact resistance of circuit breakers, isolators, busbar joints, welded joints etc., under the hostile electrostatic noise found in live EHV switchyards upto 765 kV.

Inbuilt rechargeable battery tremendously enhances utility as AC supply connectivity is not required.

CRM 100B operates on a rechargeable battery as well as Mains supply. It has a built-in constant current source, a precision instrumentation amplifi er, digital readout and control logic.A pulse of 100A DC is passed through the test object and voltage drop is sensed using the classical Kelvin’s 4 wire method to measure contact resistance. Both test current and resistance value are displayed on LCD.
