MeterTest
Three Phase Testing Stand of LS-3 Type
ISO 9001:2000
Features:
Full compatibility with the IEC 736
standard
Fully automatic
Automatic procedures for meters
testing
Efficient calibration and
legalization
Independent waveforms for
voltage and current signals
Different meter communication
systems
Network operation
The LS-3 testing stand is a fully
automatic system enabling calibration and
legalization of electric energy meters. The
automatics include power sources, reference
standards, photoelectric scanning heads and
other elements of the system. All these
elements are controlled through a Windows®
based executive program.
The use of the-latest-design signal processors
and advanced technologies of
signals
synthesis, as well as the unmatched precision,
quality and functionality qualify the system
for testing all kinds of electric energy meters
available on the market, form the simplest
electromechanical ones to multi-functional
electronic meters, including the prepaid,
multi-system, multi-quadrant meters with
power recorders, and other.
For determining the tested meters errors, the
LS-3 testing stand employs the reference
standard meter method. The error of the
tested meter is determined by counting
impulses generated by the reference standard
MeterTest
within gating time determined with the
photoelectric scanning head, which detects
the meter disc movement or with the LED
flash of the tested meter.
All kinds of other tests indicated in the subject
norms are available, such as the test of no-load
condition, the test of starting condition, the test
of meter constant, the test of maximum power
demand indicator, and many other. An
important feature of the system is the fact that
it performs automatically
additional
operations facilitating the testing process,
which are not defined in an open way, e.g. the
system automatically sets tested meters in the
mark-in-front position before performing the
test of no-load condition or the test of starting
condition.
Thanks to excellent parameters, great
functionality and flexibility the LS-3 testing
stand finds application in national laboratories
of metrology and other customers interested in
electricity
meters
testing.
