    The Motwane Hi-Pot tester, HVT series offer wide range of test voltages to determine the withstand strength of electrical insulation for the normally occurring over voltage transients. HVT series Sets are available in a wide range of voltage and power ratings with exceptional reliability, durability and functionality which can generate AC, DC or AC+DC Voltages (eliminate the need for two separate kits). It is available with manual / motorized controlled operation and provides variable output voltage. Test sets had selectable tripping current to identify breakdown voltage of different test objects and also have timer, useful to set duration of test period. HVT series is provided with HV indication, supply fault / earth open interlocking & door / cabin interlocking & overload protection provided for safety of operator & test set.

    Dielectrics (insulation) for electrical equipment and apparatus is used for many different applications. It is expressed for a wide range of environmental conditions such as temperature, moisture, chemicals, other contaminants, and exposure to weather. One major factor affecting insulation life is thermal degradation. Although moisture, contamination, voltage stress, and other factors may also contribute to its degradation. In addition, the life of an insulating material depends on the degree of loading, the type of service to which the equipment is subjected, the care it receives during installation and operation, and mechanical vibration and forces to which it is subjected. 

    A dielectric withstand test is an electrical test performed on a component or product to determine the strength of insulation. The voltage is applied between equally insulated sections of a part or energized parts and electrical ground under test, and determines the leakage current that may flow under test conditions. Excessive leakage current flows may indicate a deteriorated condition or impending failure of the insulation. Insulation testing can be performed by applying either direct current (DC) voltage or alternating current (AC) voltage. The test is to qualify a device’s ability to operate safely during rated electrical conditions. If the current through a device under test is less than a specified limit at the required test potential and time duration, the device meets the dielectric withstand requirement. A dielectric withstand test may be done as a factory test on new equipment, or may be done on apparatus already in service as a routine maintenance test.
