High Voltage Breakdown Tester Pdf

Testing of isolators and circuit breakers cables.

High voltage breakdown tester pdf. V k t v 0. Performed by stressing the insulation of the product far. 2 9 is limited to values of k t close to unity for k t 0 95 it is. The hipot test the dielectric voltage withstand test is commonly known as the hipot test.

The test is usually performed at about 75 of the typical breakdown voltage and is done as a safety net. The fluke 1555 insulation resistance tester offers digital insulation testing up to 10 kv making it ideal for testing high voltage equipment including switchgear motors generators and cables. High voltage breakdown tester or hv tester is useful for measurement of breakdown flashover voltage of electrical components insulation materials instruments transformers etc. Therefore if we use dc test voltage we ensure that the dc test voltage is under root 2 or 1 414 times the ac test voltage so the value of the dc voltage is equal to the ac voltage peaks.

Designed to verify that the insulation of a product is adequate enough to withstand high voltage. High voltage breakdown tester seco make high voltage breakdown tester is used for testing of dielectric strength of different insulating materials used in electrical equipment products and parts like control panels transformers motors cables insulating material sheets switch gear. Trusted for the most technically advanced portable and user friendly high voltage equipment on the market. Remote operation lets you spend as little time as possible in potentially hazardous zones.

Vice versa when a test voltage v 0 is specified for standard reference atmo sphere the actual test voltage value can be calculated by the converse procedure. High voltage testing of electrical apparatus. Testing of insulators and bushings. 2 6 the applicability of eq.

ð2 9þ because the converse procedure uses the breakdown voltage v 50 eq. Hipot test is the most common type of electrical safety test. Can be used to ascertain quality of insulation material before planning their usage in electrical applications. Designs and manufactures industry leading high voltage test equipment for proof testing diagnostic testing high voltage breakdown testing and preventative maintenance testing.

The test is sensitive to arcs or corona so it often finds terminal spacing problems over mold problems tolerance errors in idc cables or any problem that might produce arcs. Data collection is easy using the fluke connect wireless app. High voltage breakdown testers high voltage testers hi pot testers manufacturer exporter pune india. For example for a 1500 v ac voltage the equivalent dc voltage to produce the same amount of stress on the insulation would be 1500 x 1 414 or 2121 v dc.
