EARTHING CONTACT RESISTANCE TESTER is a basic safety test prescribed in many standards to test samples for the proper connection of Earthing with appliance or Unit, throughout the sample. The fall-of-potentialtestmethod is used tomeasurethe ability of anearth groundsystem or an individual electrode to dissipate energy from a site. Theearthelectrode of interest must be disconnected. Thetesteris then connected to theearthelectrode.It checks the contact resistance between accessible metal parts of the Appliance and Earth by passing a high current and measuring the resultant voltage drop. (The principle of measurement is Ohms Law) and the metering and transformers are properly designed to obtain accurate results. The appliance is placed on an insulating surface. The EARTH terminal of the electrode is firmly fixed to the main Earth terminal of the appliance The heavy duty cables and crocodile clip is firmly connected to the appliance that nullify the cable resistance or minimize the resistance when connected to various accessible metal parts of appliance or unit and a high current is passed between OUTPUT and EARTH.

The DIELECTRIC HIGH VOLTAGE TEST is an integral part of the product safety evaluation of electrical and electronic devices, and provides manufacturers with important information regarding the quality and appropriateness of the chosen insulation system. This test is a property of interest for many fields where electric field is present.This test involves placing an high voltage across the insulation barrier of the device as per Indian and International Standards. If the insulation holds the voltage, the device is deemed to have passed the test. However, if the applied voltage allows current to flow through the insulated device after its breakdown , then insulation is determined to be insufficient since it might pose a shock hazard to users. Since Its related to the shock hazard to the end users thats why it is a very important test.

The DRY ARC RESISTANCE TESTER is designed to meet specific conditions to meet ASTM D 495-99 (2004) & UL 746 A supplied with Tungsten Electrodes.This test method covers, in a preliminary fashion, the differentiation among similar materials with respect to their resistance to the action of a high-voltage, low-current arc close to the surface of insulation, intending to form a conducting path therein or in causing the material to become conducting due to the localized thermal and chemical decomposition and erosion.

The intent of arc resistance testing is to distinguish between solid electrical insulating materials. It examines the specimens ability to resist an arc with high voltage and low current exposed to the materials insulating surface. The ASTM arc resistance test for dry and uncontaminated materials centers on the time elapsed until tracking paths form.

The high voltage breakdown tester is commonly used for determining the dielectric breakdown voltage strength in material through the thickness of a test specimen as per relative Indian & international codes.The high voltage strength of an electric insulating material is a property of interest for any application where an electrical field will be present. The conditions are applied between the insulating & conducting material. The test, which is specified here in may be used to provide part of information needed for a given application & also for detecting changes or deviations from normal characteristics resulting from processing variables, aging condition or other manufacturing or environmental situation. This method is useful for process control, acceptance or research testing.

Generally used to test the insulating properties of winding of transformers, ballast and motors etc.

Double the rating voltage and double the rated frequency Or five times the rating voltage and five times the rated frequency With necessary voltage and frequency display With tripping facility to obtain the insulating strength of the winding.
