The high voltage test also called dielectric strength test or hipot test can be made in ac or dc.
Ac high voltage test set.
The ac voltage test set t 22 1 is a portable test set consisting of two separate units.
0 to 3kv 0 to 5kv.
Further these testing sets are capable of giving continuously variable ac high voltage from zero to maximum rated output voltage.
The pft 301cm and pft 301cmf are from our popular pft series of field portable ac hipot test sets.
Gdtf 4500 750 variable frequency ac resonant test system gdtf 250 50 ac resonance test set gdtf 250 50 ac resonance test set gdtf 240 240 ac resonant test system gdtf 240 240 variable frequency ac resonant test system gdzg s water cooled generator tester gdzg s water cooled generator dc hipot tester gdfr c1 series ac dc voltage meter.
These hipots provide continuously adjustable ac voltage used for a pass fail ac over voltage withstand test on high voltage apparatus like switchgear circuit breakers reclosers vacuum bottles hot sticks bus duct and any other apparatus needing an.
0 30 kv ac power frequency ac hipot.
In the hv side tripping current can be adjusted at 25ma 50ma.
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.
The 6cp line is equipped with digital metering and easy to use controls.
These are among the smallest lightest and most economical ac hipots available.
Ac dielectric test sets a complete test system in a mobile package simple to set up and operate lightweight and ruggedly constructed.
If the high voltage test is made in dc it is then combined with insulation.
230v 10 50 60hz 1ΓΈ ac.
The 6cp and 6cb line consists of a combination control and regulator enclosure and separate high voltage section.
Measurement of high voltage test under alternating current is.
These high voltage testing sets are suitable for power frequency ac high voltage test on transformers motors insulators cables etc.
This division enables the operator to use the test set on site without transport aids.
Ntpl make 3kv or 5kv ac high voltage breakdown bdv test set is ideal for testing of breakdown withstand test of electrical electronic components etc.
Voltage ratings are from 5 kv ac 300 kv ac.
Standard models are available from 10 kv ac 100 kv ac and rated 1 kva 3 kva.
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.
The control unit and the high voltage unit.
