The Type 2J6 Knopp Uniload Voltage Transformer Test Set consists of three major parts:

• A Knopp Precision Multirange Voltage Transformer Standard with four primary ranges (from 14,400 volts to 36,000 volts) and a 120 volt secondary.
• A Knopp Heavy-Duty Supply Transformer with a primary of either 120 volts or 240 volts (as ordered) and with secondary ranges the same as the primary ranges of the precision transformer standard.
• A mounting base which aligns and supports the above two transformers.

When the Knopp Precision Transformer in the 2J6 set is compensated for, and used with, a secondary burden of 15 volt-amperes, for example, the ratio of this precision transformer is well within 0.02% and the phase angle is well within 2 minutes. The transformer, in common with other Knopp Precision Multirange Transformers, is wound so that it has practically the same ratio and phase angle accuracy on all ranges.

This Type 2J6 test set is available in various models, shown in the Equipment Documentation below. Custom versions are also available
