Taylor made: two truly special voltage stabilisers

Destined for a prestigious project
for a grand Hotel in Qatar, two truly special Sirius voltage stabilisers are in
the process of being shipped.
Manufactured “off-catalogue”,
according to the customer’s specifications, the two voltage stabilisers are
top-of-the-range Sirius models and have a power of 1600kVA and extreme input
voltage regulation: ±40%.
These specifications led to the
production of very large magnetic components; in fact, the total weight of the
machines is a good 11,700 kg.
The Sirius range of the
highest-performance and most complete voltage stabilisers in our production, is
encountering a lot of success on the market.
Sirius is available for powers
ranging from 60 to 6000kVA, with ±10%, ±15%, ±20%, ±25%, ±30%, +15/-35%, and
+15/-45% adjustment. The control logic is managed by two DSP microprocessors
(one that implements the control and the other that manages the measurements)
that stabilise the output voltage, adjusting the true-RMS (root mean square)
thereof. The whole system is supervised by a third (bodyguard) microprocessor
that checks the correct operation of the other microprocessors.
In addition to the generous size and
additional protections, which make the equipment very reliable and durable, the
user interface is undoubtedly another very important feature.
Consisting of a 10-inch,
multilingual touch display (equipped with an RS485 port), it can provide
information on the state of the lines upstream and downstream of the voltage
stabiliser (voltage, current, power factor, active power, apparent power,
reactive power, etc.), the operating state of the stabiliser (it displays all
the information relating to each operating mode: on/off, adjustment limit
reached, increase/decrease in adjustment, etc.), and any alarms (minimum and
maximum voltage, maximum current, excessive temperature, etc.).
If connected to a network via
Ethernet with an RJ45 cable, the display can, in addition, be remotely
transmitted to a PC using VNC software. It is, in addition, possible to
interface with the stabiliser using the Modbus TCP/IP protocol (a standard
protocol in communicating between industrial electronic devices). The system is
also equipped with two USB ports that can be used to download the data stored
and upload software updates from the control card.
The interface possibilities widen
with Ortea Cloud, the new Ortea platform for remotely monitoring voltage
stabilisers.
