OPERATION
The H8051 and H8053 pulse output meters combine microprocessor-based kWh
transducers and high-accuracy split-core instrument grade current transformers (CTs)
in one unit. The H8051 is a single CT version designed for balanced loads, and the
H8053 is a 3-CT version for monitoring each phase. Integration of electronics lowers
hardware and installation costs. The sensors automatically detect phase reversal, so
CT load orientation is not a concern. The CTs and meters are calibrated as a set, so it is
necessary to color-match the CTs and voltage leads when installing.
These devices are used in tenant submetering, performance contracting, and
departmental costing applications. The 1% total system accuracy conforms to
ANSIC12.1 metering standards.

wiring or low power factor (less than 0.5); fast red for max. current exceeded.
5. Pulse Rate Switches: used to set the pulse output rate.
6. External CTs: permanently attached; do not disconnect or use with other power
meters.
Color match CTs and voltage leads! Example: clamp the red
labeled CT around the power conductor connected to the
red voltage wire.
