INDOTECH INSULATION RESISTANCE TESTER
Indotech INSULATION RESISTANCE TESTER (INSULATION TESTERS)- The Insulation Resistance Test is the second test required by the electrical safety testing standards. The Insulation Resistance Test consists in measuring the Insulation Tester of a device under test, while phase and neutral are short circuited together. The measured resistance has to be higher than the indicated limit from the international standards.
An insulation resistance (IR) test measures the total resistance between any two points separated by electrical insulation. The test, therefore, determines how effective the dielectric (insulation) is in resisting the flow of electrical current. Such tests are useful for checking the quality of insulation, not only when a product is first manufactured but also over time as the product is used.
Performing such tests at regular time intervals can detect impending insulation failures before they occur and prevent user accidents or costly product repairs.
As shown in Figure 15, the 2-wire ungrounded connection is the recommended setup for testing ungrounded components. This is the most common configuration for testing 2-terminal devices such as capacitors, resistors, and other discrete components.
Referring to Figure 16, the 2-wire grounded measurement is the recommended connection for testing grounded components. A grounded component is one in which one of its connections goes to an earth ground, whereas an ungrounded component is one in which neither connection goes to earth ground. Measurement of insulation resistance of a cable in a water bath is a typical application of a 2-wire grounded connection.
General: Insulation failure is one of the most common causes of electrical breakdown . Regular testing , however will
revel insulation weakness at an early stage & before serious damage can occur . The safe & effcient
operation of electrical installation depends to a large extent onon materials .
‘‘INDOTECH’’ Insulation testers provide the most accurate & reliable means for the direct reading of
insulation resistance of Electrical machinery.
