VT Voltage Designations

14400/24940YThis unit is rated for 14400 operating Volts. It can be connected at14400 Volts line-to-ground on a 24940 Volt system (line-to-line Voltsare 24940 V) OR it can be connected line-to-line on a system with14400 V line-to-line. This unit is not suitable for operation at 24940Volts. The "Y" indicates it has two fully insulated bushings, suitable forline-to-line connection.

14400/24940GYThis unit is rated for 14400 operating Volts. It can be connected at14400 Volts line-to-ground on a 24940 Volt system (line-to-line Voltsare 24940 V). It CANNOT be connected line-to-line. The "GY"indicates it only has one fully insulated bushing, making it suitable forline-to-ground connection only.

14400/14400YThis unit is rated for 14400 operating Volts. It can be connected at14400 Volts line-to-line.

14400/14400GYThis unit is rated for 14400 operating Volts. However, it can only beconnected line-to-ground on a 14400 V system. Therefore, the actualoperating voltage of the unit would be 14400/1.73. The accuracy andthermal ratings of this unit are based on 14400 V. This is typicalwhere there is a relay connected to the unit which should operatewhen there is a single line-to-ground fault. In this condition, the line-to-ground voltage becomes equal to the line-to-line voltage. Thisunit is not suitable for line-to-line connection as indicated by the "GY".

CT Rating Factors: Rating factors given in this brochure are standard at 30ºC. See thethermal loading guide on page 74-75 for derating for higher averageambient temperatures.

Transformers in this booklet conform to the following standards where applicable:

Auxiliary CTs offer a wide selection of turns ratios for use inchanging the overall ratio of main CTs. Available ratios can bedetermined from the winding (wdg.) turns tabulation. The maximumcontinuous current rating of multi-ratio transformers can becalculated as follows:

Full wdg. Imax = 1600/Full winding turns

Tap conn. Imax =

Example: 7881A02G03• Wdg. 1-4 = 133 turns, Imax = 1600/133 = 12 amps.

• 2-part wdg. (series) = 160 turns, Imax = 1600/160 = 10 amps.

• 2-part wdg. (/ /) = 80 turns, Imax = 1600/80 = 20 amps.

• Tap conn. 1-2 = 80 turns, Imax = = 15.5 amps.

Single ratio auxiliary CTs have a nominal output of 5 amperes and acontinuous current rating factor of 1.33.

AACCCCUURRAACCYY SSTTAANNDDAARRDDSSCurrent Transformers

The accuracy classification of current transformers for metering service includes acorrelation between ratio correction factor and phase angle so as to show the overalleffect on watthour meter registration. The classification is based on the requirement thatthe transformer correction factor (the correction for overall error due to both ratio errorand phase angle) be within the limits specified. For any particular accuracy class the ratiocorrection factor and phase angle must fall within the parallelograms for 100% and 10%current respectively.

For example, the overall correction will never exceed .3% at 100% rated current fora transformer in the 0.3 accuracy class. If the ratio correction factor is 1.003 themaximum allowable phase angle is +15.6 minutes. The transformer correction factor is:

The corresponding ratio correction factor and phase angle for any point inside the 0.3class parallelogram for 100% rated current will always give a transformer correctionfactor between .997 and 1.003.

Voltage TransformersThe accuracy classification of voltage transformers for metering service includes a

correlation between ratio correction factor and phase angle so as to show the overalleffect on watthour meter registration. The classification is based on the requirement thatthe transformer correction factor (the correction for overall error due to both ratio errorand phase angle) be within the limits specified. For any particular accuracy class the ratiocorrection factor and phase angle must fall within the parallelogram. These limits applyover the voltage range of ± 10% of the rated voltage at rated frequency.

For example, the overall correction will never exceed .3% for a transformer in the 0.3accuracy class. If the ratio correction factor is 1.003 the maximum allowable phase angleis - 15.6 minutes. The transformer correction factor is:

The corresponding ratio correction factor and phase angle for any point inside the 0.3class parallelogram will always give a transformer correction factor between .997 and1.003.
