The control unit and the high voltage unit.
Ac high voltage test set.
In the hv side tripping current can be adjusted at 25ma 50ma.
This division enables the operator to use the test set on site without transport aids.
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 pft 301cm and pft 301cmf are from our popular pft series of field portable ac hipot test sets.
Measurement of high voltage test under alternating current is.
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.
These are among the smallest lightest and most economical ac hipots available.
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.
These high voltage testing sets are suitable for power frequency ac high voltage test on transformers motors insulators cables etc.
0 to 3kv 0 to 5kv.
If the high voltage test is made in dc it is then combined with insulation.
The test set can be equipped with a rectifier attachment for dc voltage testing up to 80 kv.
The ac voltage test set t 22 1 is a portable test set consisting of two separate units.
The 6cp and 6cb line consists of a combination control and regulator enclosure and separate high voltage section.
Further these testing sets are capable of giving continuously variable ac high voltage from zero to maximum rated output voltage.
0 30 kv ac power frequency ac hipot.
The high voltage test also called dielectric strength test or hipot test can be made in ac or dc.
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.
Pft series test sets are portable ideal for testing substation apparatus.
Standard models are available from 10 kv ac 100 kv ac and rated 1 kva 3 kva.
The 6cp line is equipped with digital metering and easy to use controls.
Voltage ratings are from 5 kv ac 300 kv ac.
If the high voltage test is made in ac it is then this is then more stressful for the sample and made according to the sketch below.
