Indoor Voltage Transformer ANSI Groups 4A & 4B Medium Voltage Accuracy Class Thermal Rating 0.3 WXMYZ 1.2ZZ at 100 % rated voltage with 120 V based ANSI burden. 0.3 WXMY, 1.2Z at 58 % rated voltage with 69.3 V based ANSI burden. Maximum System Voltage 25.5 kV, BIL 125 kV. REGULATORY AGENCY APPROVALS Manufactured to meet the requirements of ANSI/IEEE C57.13. NOTE: All primary voltages marked with an asterisk (*) are approved for revenue metering in Canada by industry Canada, Approval No. AE-0676 Rev.2

Recommended Minimum Spacings A = Unit to Unit = 1.50” minimum. B = HV to Ground in Air = 8.50” minimum. Recommended spacing are for guidance only. User needs to set appropriate values to assure performance for high potential test, impulse test, high humidity, partial discharge, high altitude, and other considerations like configuration. (a) Also available are other ratios and frequencies, double secondaries and units meeting IEC 44-2 rated voltage factors of 1.50 or 1.90. (b) Voltage transformers connected line-to-ground cannot be considered to be grounding transformers and must not be operated...
