Note: The instrument must be installed on the spot together with a complementary
split-core current transformer .
1Overview
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.
