Meter features :-
• LED display screen: Intuitive self-guided navigation using three buttons LED display, with three lines of concurrent values. Two columns of LEDs given on the either side of the meter’s front panel indicate the parameter name being
displayed.
• Energy accounting and balancing.
• Measurement of both True PF and Displacement PF.
• EM6400NG+ POP (Class 1 and 0.5S) and RS-485 (Class 1, 0.5S, and 0.2) models.
• THD% and individual harmonics up to 15th order for voltage and current.
• Active, reactive, and apparent energy readings.
• Min/Max values of instantaneous parameters with timestamp.
• Cybersecurity: The meter supports the disabling of RS-485 port through front
panel keys to prevent unauthorized access. Toggle the RTU devices in case of limited availability of nodes in software system.
• Suppression current: The meter can be configured to disregard the
measurement of induced / auxiliary load current in the circuit (can be set from 5 to 99 mA).
Serial communications :-
The meter supports serial communications through the RS-485 port. Up to 32 devices can be connected on a single RS-485 bus. In an RS-485 network, there is one master device, typically an Ethernet to RS-485 gateway. It provides the means for RS-485 communications with multiple slave devices (for example, meters). For applications that require only one dedicated computer to communicate with the slave devices, an RS-232 to RS-485 converter
can be used as the master device.
Balanced 3-phase Wye system with 2 CTs :-
The current for the unconnected current input is calculated so that the vector sum for all three phases equal zero.
Balanced 3-phase Wye or Delta system with 1CT :- The currents for the unconnected current inputs are calculated so that their magnitude and phase angle are identical and equally distributed, and the vector sum for all three phase currents equal zero.
