- Abstract:
- We have developed a series of high stable and accurate potential transformer with cascade arrangement to reduce the size and weight for the on-site calibration and field application.
The maximum rated voltages of the PTs were 22 kV, 66 kV and 132 kV with rated burden of 5 VA. The long term stabilities of ratio error of the PTs were less than 0.0033 %, and ratio errors were (-0.0022 ~ + 0.0442) %. The phase angle errors were less than about -3 min and the maximum long term drifts were 0.077 min. - Keywords:
- cascade arrangement, PT comparator, on-site calibration, potential transformer, ratio errorand phase angle error
