Construction of the meter<br />
In its standard version, the LE <strong>3000plus</strong> electricity meter consists of three basic elements:<br />
shunt for current measurement in the main circuit,<br />
measuring unit (high-voltage),<br />
communication unit (low-voltage).<br />
The HVM measuring unit of LE<strong>3000plus</strong> is powered only from the 3.3 kV or 660 V DC voltage<br />
being measured. Voltage, current, and energy measurements are performed in the unit.<br />
The LE <strong>3000plus</strong> HVM module is adapted for measurements of both power consumed and power<br />
returned, and at the same time each of the types of power being measured is counted<br />
and recorded separately. For the current measurement, voltage drop at the outer shunt is used,<br />
the shunt being placed in the current main circuit in the plus rail potential.<br />

The purpose of the communication unit (KOM) of the LE <strong>3000plus</strong> meter is to process, present<br />
and record the data received from the measuring unit, and to communicate when a remote readout is<br />
needed. The data from the meter may be read locally using a USB port and dedicated software provided<br />
by the manufacturer, or remotely via GPRS transmission (upon user's request) and periodically<br />
to an FTP server.<br />
The communication module is provided with a touch memory reader enabling<br />
identification of the carrier, thus the data from the meter may be used<br />
for settlement of accounts for several electricity consumers at the same time.<br />
The LE KOM module performs also a localization function of rail vehicles, thanks<br />
to an incorporated GPS module. This function is used in cases when a moving<br />
vehicle consumes energy provided by various providers.<br />
LCD display of the LE<strong>3000plus</strong> KOM module presents current values of the voltage and current<br />
being measured as well as power counters' readings, thanks to which the meter is simultaneously<br />
a panel meter for main circuit parameters. Moreover, it is possible to exchange data with other onboard<br />
instruments via CAN or RS-485 interfaces.<br />
