The Power Quality problems of an electrical distribution network are often generated locally within the structures and can depend on various situations, such as, for example, construction works, switching on high loads, faulty distribution components and particular basic electrical disturbances.
Furthermore, external causes such as atmospheric events (hurricanes, lightning, snow, ice and floods), equipment failures, short circuits, and load switching operations can generate additional power quality problems especially on very large power distribution lines.
Particularly complex power quality problems can be characterized by the combination of several unwanted electrical perturbations such as voltage surges, high frequency conducted disturbances and voltage spikes.
Ministatic and Steroguard IREM Line Conditioners have been designed to provide the highest level of protection to electrical appliances connected to distribution lines disturbed by sudden voltage variations, HF noises and spikes.
Statistically, the phenomena that reduce the power quality of the energy supplied by the network represent more than 95% of electric anomalies that could be the cause of breakdowns and poor operation of any kind of appliance connected to distribution lines.
IREM Line Conditioners guarantee maximum protection to users subject to particular power grid anomalies and drastically increase the level of power quality.
- a suppressor of voltage spikes;
- a line filter;
- a high attenuation isolation transformer;
- a voltage regulator.
The range of IREM Line Conditioners is made up of models with powers that vary from 0.5 to 950 kVA and use two different voltage regulation technologies:
a. static switching technology for loads with singlephase absorption (up to 4 kVA) and three-phase (up to 24 kVA);
b. electrodynamic regulation technology via series transformer and variable autotransformer for loads with three-phase absorption (up to 950 kVA).
The two regulation technologies and the wide range allow the most suitable regulation system to be supplied to meet the specific needs of power quality of various kinds of appliances.
MINISTATIC ELECTRONIC LINE CONDITIONERS
IREM Electronic Line Conditioners have specific performances to power electronic appliances with medium to low powers that require a particularly high stabilisation speed such as: process and numerical controls, robotics, medical equipment, telecommunications and computers.
The range is made up of standard models with powers ranging from 0.5 to 24 kVA. Furthermore, because the manufacturing criteria make these power conditioners highly versatile, on request, versions can be designed with customised specifications for the most varied applications.
STEROGUARD ELECTRODYNAMIC LINE CONDITIONERS
IREM Electrodynamic Line Conditioners provide a maximum level of protection to high power appliances, with high electromagnetic susceptibility, connected to distribution lines disturbed by sudden voltage variations, high frequency interferences and voltage spikes. The voltage regulation system is made up exclusively of magnetic components capable of supporting loads with high inrush currents. The use of electronic components is limited to mains control and command of the magnetic components that stabilize the voltage. Thanks to these features, the electromechanical line conditioners stand apart for their high electromagnetic immunity and for the reliability characterised by a MTBF longer than 500,000 hours. They are, therefore, particularly suitable to solve power quality problems of electric users like radio-TV transmitters, telephone systems, radar systems, motors, compressors, pumps, medical equipment, machine tools and so on.
Their constructive features ensure that maintenance can be carried out even by technical staff with only a basic knowledge of electrical installations.
