5 Metering and Monitoring
5.1
Overview
The PowerView metering module will be used to monitor various voltages & currents in a power
distribution panel or remote power panel. The meter will also compute various other parameters such as
power, energy, demand, frequency, power factor, etc. Specific parameters for transformers, branches
and sub-feeds are shown in Section 5.5.
This unit is equipped with ABB's PowerView monitoring system. Instructions
regarding monitoring can be found in PowerView Manual 94-1100-00002861.
The reader is expected to know the fundamentals of electricity, wiring, electrical
components and electrical schematic symbols.

Product description
The Metering module board will acquire the voltage & current signals from an analog signal conditioning
board. It will calculate energy and power quality parameters. PowerView can also monitor discrete or
thermocouple inputs, if so equipped. These parameters are passed to the display board/PC for display
and data logging. It will also receive control/command/system parameter data from display board or a
third-party display module.

Features
The following are standard features of distribution products equipped with PowerView:
1. Thermal shutdown (shunts trip input breaker when goes past acceptable thermal levels).
2. TVSS or surge arrestor fault indication. This indication could mean that there is a fault with the
TVSS or the surge arrestor (if applicable).
3. Over temperature warning.
4. Manual restart (requires a "manual restart" of the input breaker when there is a power outage).
5. Local Emergency Power Off button (EPO).
6. Remote Emergency Power Off contacts (REPO).
5.4
Modbus
The PowerView with HMI acts as a Modbus slave, and can be accessed by the Modbus master using either
Modbus RTU (via RS-485) or Modbus TCP through customer connection on the UIB Modbus port. The
PowerView with HMI is identified by a unique slave ID=1 by the master. The default Modbus RTU settings
are as follows.
