Potential Transformer

The standards define a voltage transformer as one in which "the secondary voltage is substantially proportional to the primary voltage and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections. Their role in electrical systems is of primary importance as they are a means of "stepping down" the current or voltage of a system to measurable values 110V or 100V in the case of a voltage transformer

  • Rated voltage :3kv ,10kv or 12kv
  • Rated voltage ratio :  3000/100V; 6000/100V    ;10000/100V; 11000/110v
  • Rated insulation level : 3.6/28/40 KV ; 7.2/32/60KV ; 12/42/75KV
  • Protection :3P     Burden:60VA---100VA
  • Accuracy class : metering :0.2 ; 0.5 ; 1  Burden:10VA ---60VA
