Meter and Relay Applications for theElectrical Industry
Note: For Current and Voltage Transformer Pricing Information refer to: 600 V -PL 42-8005 kV-36 kV -PL 42-900
The transformers listed in this guide represent those mostcommonly built for the electric utility industry but are a smallsample of what we actually offer. For special designs or unitsnot listed please contact your local ABB representative.
VT Voltage Designations
14400/24940YThis unit is rated for 14400 operating Volts. It can be connected at14400 Volts line-ground on a 24940 Volt system (line to line Volts are24940 V) OR it can be connected line to line on a system with 14400V line to line. This unit is not suitable for operation at 24940 Volts.The "Y" indicates it has two fully insulated bushings, suitable for lineto line connection.
14400/24940GYThis unit is rated for 14400 operating Volts. It can be connected at14400 Volts line-ground on a 24940 Volt system (line to line Volts are24940 V). It CANNOT be connected line to line. The "GY" indicates itonly has one fully insulated bushing, making it suitable for line toground 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 toground voltage becomes equal to the line to line voltage. This unit isnot 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 70-71 for derating for higher averageambient temperatures.
Transformers in this booklet conform to the following standards where applicable:
1) IEEE Standard Requirements for Instrument Transformers,C57.13–1993.
2) ANSI Standard for Instrument Transformers for MeteringPurposes, 15 kV and less, C12.11–1987.

Current TransformersThe accuracy classification of current transformers for metering service includes a
correlation between ratio correction factor and phase angle so as to show the overall effecton watthour meter registration. The classification is based on the requirement that thetransformer correction factor (the correction for overall error due to both ratio error andphase 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 the maximumallowable phase angle is +15.6 minutes. The transformer correction factor is:
The corresponding ratio correction factor and phase angle for any point inside the 0.3 classparallelogram for 100% rated current will always give a transformer correction factorbetween .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 overall effecton watthour meter registration. The classification is based on the requirement that thetransformer correction factor (the correction for overall error due to both ratio error andphase angle) be within the limits specified. For any particular accuracy class the ratiocorrection factor and phase angle must fall within the parallelogram. These limits apply overthe 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 angle is- 15.6 minutes. The transformer correction factor is:
The corresponding ratio correction factor and phase angle for any point inside the 0.3 classparallelogram will always give a transformer correction factor between .997 and 1.003.
