Phase Electrical Systems
1Introduction
This document provides operating, maintenance and installation
instructions. This unit measures and displays the characteristics of
Single Phase Two Wire (1P2W) and 2 x (C1 & C2) Three Phase Four
Wire (3P4W) networks. The measuring parameters include Voltage
(V), Current (A), Frequency (Hz), Power (kW/KVA/KVAr), Power
Factor (PF), Imported, Exported and Total Energy (kWh/kVArh). The
unit also measures Maximum Demand Current and Power, this is
measured over preset periods of up to 60 minutes.
