Installation of the meter in a traction substation
The LE 3000plus Energy Meter can be installed in a traction substation (rectifying station) and used
for counting the power returned to the 3.3 kV (660 V) switching station by rectifying sets. This solution
allows for monitoring the efficiency of traction transformers and rectifiers. The system for measuring
the power returned to the DC switching
station is shown in the figure. In this system,
the meter's measuring shunt is included
in the collective rail of the “plus” pole,
between the cathodes of the rectifying sets
and outflows to the traction line (fields
of traction power units). Construction of
the LE 3000plus HVM measuring transducer
and the LE 3000plus KOM communication unit
is identical as in case of the solution for traction
vehicles, however the communication unit
is adapted to be powered by 220 V DC or
230 V DC voltage from own needs switching
station of the traction substation.
Installation of the meter in a section
cubicle
The LE 3000plus electricity meter can
also be installed in a section cubicle at the
border of two infrastructure administrations.
Depending on the cubicle function, the meter
can be installed on a collective rail or on
a selected outflow (e.g. to an electric
locomotive depot or ZNTK Rolling Stock
Repair Plants). The meter's communication
unit is powered from cubicle's own needs
with 230V AC or 220V DC voltage.
An example diagram of a 3.3 kV
measuring system in a section cubicle is
shown on the right.
The first LE 3000plus energy meter in
a cubicle version was installed in
KS Newag Nowy S¹cz as ordered
by “PKP Energetyka” Southern
Plant. It is used for settlements
of electricity supplied to a siding
of the NEWAG S.A. plants.
