This guide provides a description of the VerifEye Series 8000 PT (potential transformer) module and
procedures for installing and maintaining the module.
This documentation is intended for those responsible for installing and maintaining the VerifEye PT
(potential transformer) module. Installers must be qualified electricians with knowledge of local and national
code requirements. See Warnings and Cautions.
1.1 Description and specifications
The VerifEye Series 8000 PT module provides step-down voltage connections to VerifEye Series 8000
meters for metering single-phase to three-phase voltages of 600V, 347V, or 400V, while meeting all
regulatory electrical safety and ANSI 0.5 Accuracy Class standards. The VerifEye Series 8000 PT module
provides both the per-phase input metering sense voltages and the auxiliary input power required by
VerifEye Series 8000 energy meters.
There are two variants of the VerifEye Series 8000 PT module that support the following source voltages
and wiring configurations:
1.
The 347V Wye / 600V Delta variant supports:
• 347V, three-phase, 4-wire wye
• 600V, three-phase, 3-wire delta
2.
The 480V Delta variant supports:
• 480V, three-phase, 3-wire delta
The 347V/600V PT module variant has three sense voltage potential transformers for metering. The
configuration of the transformers (347V wye or 600V delta) is selected by using the jumper provided.
The 480V PT module has two sense voltage potential transformers for metering.
There is a separate auxiliary power transformer in both variants to operate the meter. All voltage inputs
are fused.
One VerifEye Series 8000 PT module can be used to provide sense voltages and auxiliary power to a
maximum of two meters.
Table 1 lists the specifications of the VerifEye PT module.
