THE ISSUE Electricity is perhaps the most essential raw material used by commerce and industry today The electricity produced in power plants is circulated through the electricity transmission and distribution networks and it is supplied/delivered to consumers; the quality of electricity (known as «Power Quality») is one of the important factors that determine the economic efficiency of both consumers and electrical networks. Electrical devices are designed to work in distributing systems defined by set nominal values in terms of voltage and frequency (for example, 400V at 50Hz). In actual fact,...

maintenance and disposal due to the fact that batteries are not used. • Smooth and reliable regulation of the load voltage ensuring a ±0.5% accuracy even with important input voltage variation. • High efficiency. • High inrush current withstand capability. • Reduced dimension, simple to run, 'plug&play' operating mode. The voltage stabiliser has proven to be an effective solution able to prevent potentially dangerous situations created by input voltage instability The main application fields where devices sensitive to voltage variations can be used include: • Industrial sector: oil & gas, laser...

SELECTION CRITERIA Number of phases The number of phases of a stabiliser depends on the type of load: • single-phase load: single-phase stabiliser; • combination of several single-phase loads on the same line: three-phase stabiliser or a single-phase stabiliser on each load; • three-phase load: three-phase stabiliser. Rated voltage Due to the fact that the nominal voltage varies internationally, establish the rated voltage required at the stabiliser input and output. In case of threephase systems, provide with the line-to-line voltage value. The standard voltage stabiliser can operate with nominal...

ELECTRO-MECHANICAL DIGITAL VOLTAGE STABILISERS

DESIGN CRITERIA A voltage stabiliser is a power device destined to be positioned between the mains and the User. The purpose is to ensure that the User is fed a voltage subject to a variation much lower (±0.5% with regards to the nominal value) that the one guaranteed by the distributing system WORKING PRINCIPLE OF AN ELECTRO-MECHANICAL DIGITAL VOLTAGE STABILISER L1 BUCK/BOOST TRANSFORMER VOLTAGE REGULATOR VOLTAGE REGULATOR VOLTAGE REGULATOR DIGITAL CONTROL BOARD The stabilization is performed on the “true rms” voltage and it is not affected by harmonics in the mains. Due to the fact that the...

Customer’s premises according to the instructions given in the reference technical handbook. On Sirius and Sirius Advance stabilisers, the output voltage reference and the main configuration parameters can be set in different ways: • through the local touch panel; • directly by communicating with the microprocessor via a PC connection (through USB interfaces); • from a remote station via Ethernet with MODBUS TCP/IP protocol. MAIN COMPONENTS 1. Buck/boost transformer Often referred to as ‘booster’ transformer, it is a standard dry-type transformer with the secondary winding connected in series...
