Definition of Terms

  • Im: Max rated current
  • Rnv: Nominal Variation of ratio error at the mentioned primary current range
  • Pnv: Nominal variation of phase error at the mentioned primary current range
  • Rb: Burden resistance
  • PF: Power factor
  • DCR: DC Resistance of secondary winding
  • Remark: The date of maximum current, ratio and phase error on 60Hz testing would be around 20% better than those of above 50Hz
