Electric
energy accounting
systems
Our next customer SIEMENS Poland Ltd.
is also provided with our products. Catering for their needs we
produce electric energy accounting systems. They are successfully
used in power plants and energetic stations and everywhere
control and measurement of used energy is essential. The systems
are based on our cabinets (standard 19"). Here is their short
description:
Supply systems are included in power supply circuits with
guarantee voltage of 230 VAC, constant battery voltage and
auxiliary supply of 230 VAC from on-site power. High precision
meters of ZMD or ZMVQ type by LANDIS&GYR are installed in our
cabinets. The meters allow simultaneous measurement of both
active and wattles power in both directions. In addition,
depending on parameterization the meters allow to carry out not
only the square separation of wattles power but also separation
of wattles power depending on the direction of active power flow.
In the suggested solution the meter input system also includes
voltage monitoring cards and voltage relay cards.
Monitoring Circuits are based on URZ fault logger which enables
remote monitoring of chosen points both on unmanned stations and
on those with service staff. The logger has 25 digital inputs for
systems generating signals in case of fault, 6 digital outputs of
open collector type creating parallel port and 2 relay outputs.
Universal telemetric concentrator FAG 10 used in electric energy
accounting cabinet thanks to collected data processing and their
recording fulfils the highest requirements of today’s power
industry. FAG 10 enables automatic recording and processing of
meter’s value. Those data are collected from high precision
meters through an interface. In the concentrator two kinds of
inputs are used: both serial ports inputs for transmission among
the meters and pulse inputs for connecting direction loss pulse
signals from the meters’ inputs. Collected and processed data are
accessible for master system through telephone line and a modem.
P.S.A. “Zapis-Hardware” designs and produces, in coordination
with SIEMENS Poland Ltd, custom non-standard measuring cabinets
fulfilling customer’s needs.
The products made in PSA Zapis - Hardware at customer request
Thinking of our customers’ needs we manufacture products and
provide service basing on DCS and PLC systems. We are always
willing to cooperate and have been trying to cater for all our
customers’ demands.
Therefore, basing on our engineers’ knowledge and experience we
create single and specialistic applications which work in
energetic, car and processing industry. We are open to
cooperation and new technologies. We are not afraid to face
challenges or to introduce new solutions.
