Meco instruments pvt ltd supplies clamp-on ground resistance and leakage current testers. These are non-contact elements and very effective for measuring ground resistance and leakage current of electrical installations, like transmission poles, transformers, lightening arrestors, motors, high-voltage appliances and cables. These are also applied in multi-grounded systems without disconnecting the ground connection of the circuits. They provide a unique measurement system, which eliminates the use of ground and auxillary rods and saves lot if time. They also help to shun the shutdown of the installations. These are portable and user friendly. They enable the punching of auxillary electrodes, which is impossible by the traditional methods of measurement. The instruments provide a self-calibration check, which is verified by using the standard resistance template. The instrument have several standard features such as non-contact measurement, auto ranging, no auxillary electrode needed, continuity loop test, ground resistance 0.025 ohms 1500 ohms, accommodate ground wire of dia .23 mm/0.9", etc.
