Universal Metering Transponder for kV2c™ Meter User Guide 31
Chapter 2 • Functional Description
Voltage Transformer (VT) Connected Meter/Transponder
TWACS-enabled kV2c meters that are configured for Voltage Transformer (VT)
connected installations must be treated differently than kV2c meters designed for
direct line voltage applications.
VT-type kV2c meter/transponder hardware combinations are not compatible with
any other kV2c meter/transponder combinations and are, consequently, not
interchangeable. kV2c VT-type meter/transponder combinations are designed to
operate exclusively on either the primary or the secondary winding side of voltage
transformers with nominal secondary voltage of 120V ± 15%.
C AUTION Installation of the VT version of a TWACS-enabled kV2c meter on direct line
connected locations without Voltage Transformers could lead to destructive
failure of the device during TWACS communication.
All VT connected meter/transponder combinations are configured at the time of
integration with the necessary parameters for proper TWACS communication.
N OTE Installed meters, or meters in the meter shop, can not be retrofitted for VT
applications. New VT meters only must be installed for VT applications.
