Dc High Voltage Test Set

Portable high voltage test set for d c.

Dc high voltage test set.

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. The pts 100 and pts 100f are combination high voltage dc proof tester and megohmmeter. 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. Abt series test sets are ideal for testing medium voltage electrical components and apparatus.

Maintain the test voltage at the prescribed value for the time specified in the applicable specifications. 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. Dielectric strength and insulation resistance testing are combined into one instrument saving time money size and weight. Generally dc high voltage test sets are available in one unit upto 35kv and sets of higher output voltage are commonly manufactured in two units i e.

Gdzg 300 dc hipot test set gdtf hvc ac resonant test system gdtf hvc ac resonant test system for cables. 70 120 160 kv dc dielectric test sets. Most hvi models offer a higher output current than competitors products for quicker charging of capacitive loads like cables. Equipped with a 5 range current meter scaled 0 1 dc microamps for accurate current.

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. Hv test set 50 kv hv test set 80 kv and hv test set 110 kv.

High pot testers 3kv 4kv ac hipot. 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. This transformer rectifier unit are made cascaded type above 80kv.
