Dc High Voltage Test Set

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.

Dc high voltage test set.

Portable high voltage test set for d c. Find trusted dc high voltage test set supplier and manufacturers that meet your business needs on exporthub qualify evaluate shortlist and contact dc high voltage test set companies on our free supplier directory and product sourcing platform. The pts 100 and pts 100f are combination high voltage dc proof tester and megohmmeter. Abt series test sets are ideal for testing medium voltage electrical components and apparatus.

Dielectric strength and insulation resistance testing are combined into one instrument saving time money size and weight. Alt series test sets are designed for testing aerial lift devices bucket trucks but can also serve as portable versatile all purpose ac testers with an output of 0 60 120 kv ac 7 kva ideal for field plant and substation testing. Most hvi models offer a higher output current than competitors products for quicker charging of capacitive loads like cables. At the end of the test period set the test set voltage to zero allow the residual voltage on the circuit to decay disconnect the power supply and then ground and drain the conductor just tested.

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. Voltage divider gdfr r series high voltage dc digital meter voltage divider gd 605 ac impedance tester gd 605 generator ac impedance tester gtb series dry type testing transformer gtb series dry type. Hv test set 50 kv hv test set 80 kv and hv test set 110 kv. Gdfr c1 series ac dc voltage meter.

The pts series combine high voltage dc hipots and hv megohmmeter instruments offering two important tests within one unit users can perform high voltage dc hipot proof and current leakage testing as well as resistance measurement testing. Hv tester 25 high voltage generator. This transformer rectifier unit are made cascaded type above 80kv. High pot testers 3kv 4kv ac hipot.

Equipped with a 5 range current meter scaled 0 1 dc microamps for accurate current. 70 120 160 kv dc dielectric test sets. Maintain the test voltage at the prescribed value for the time specified in the applicable specifications.
