The rail-type multifunction electrical instrument with external
Rogowski coil and split-core current transformer is applicable for the
energy-saving reconstruction project in high energy consumption
industries including the smelting, iron and steel, welding and
semi-conductor industry. It is also suitable for applications such as the
power monitoring of grid-connected cabinet for distributed photovoltaic
power cabinet and energy demand management. It boasts of no need of
bus removal, easy connection and safe construction, saving
reconstruction cost and raising efficiency for the user. It integrates the
measurements of all electric parameters (including single-phase or
three-phase current, voltage, active power, reactive power, apparent
power, frequency and power factor)and comprehensive energy
monitoring and examination management. Meanwhile, it also has various
peripheral interfaces for the user to choose: the RS485 communication
interface with MODBUS-RTU protocol can meet the need of online
communication management; the interfaces with switch input and relay
output can realize the remote signalling and remote control of the circuit
breaker switch. It is very suitable for real-time power monitoring system
with an LCD display and the panel buttons to realize the setting and
control of parameters.
