Automatic power-factor correction

CONSTRUCTION TECHNOLOGY

The automatic power-factor correction equipment, RG1 series is composed of:

• Metal CABINET equipped with cooling fins, made of sturdy pressed sheet metal treated with a phosphating process to protect against corrosion and then painted with epoxy powders, color RAL7035.
• Main CIRCUIT BREAKER.
• Three-pole CONTACTORS, rated for connecting the single batteries. Their peculiarity lies in the fact that the insertion contactors of the limiting resistors close in advance of the main contactors to limit the current peak at the insertion of the residual currents. The coils are 380Vac 50Hz (other voltages on request).
• The PRT series CAPACITORS.
• Internal connecting CABLES are flameproof type N07VK.
• ELECTRONIC REGULATOR for automatic battery connection and cosφ control.

USES

The RG1 series equipment has been specifically designed for industrial power-factor correction for smallscale operations.

CONSTRUCTION TECHNOLOGY

The automatic power-factor correction equipment, ERA series is composed of:

• Metal CABINET equipped with cooling fins, made of sturdy pressed sheet metal treated with a phosphating process to protect against corrosion and then painted with epoxy powders, color RAL7035.
• Main three-pole fast-tripping DISCONNECTING SWITCH interlocked with the door.
• Sets of three FUSES type DIII or NH00 curve gG with a high breaking capacity, sized to protect the capacitor banks.
• Three-pole CONTACTORS sized for connecting the single batteries. Their peculiarity lies in the fact that the insertion contactors of the limiting resistors close in advance of the main contactors to limit the current peak at the insertion of the residual currents. The coils are 110Vac 50Hz (other voltages on request).
• The CAPACITORS are the PRT.
• Internal connecting CABLES are flameproof type N07VK.
• Copper BARS size 30x5 mm.
• ELECTRONIC REGULATOR for automatic battery connection and cosφ control.
• Forced VENTILATION SYSTEM made with special, thermostat-operated fans installed on the top of the cabinet.

USES

The automatic freestanding equipment, ERA series has been specifically designed for industrial power factor correction for medium-large-scale operations.

CONSTRUCTION TECHNOLOGY

The automatic power-factor correction equipment, ERAF series is composed of:

• Metal CABINET equipped with cooling fins, made of sturdy pressed sheet metal treated with a phosphating process to protect against corrosion and then painted with epoxy powders, color RAL7035.
• Main three-pole fast-tripping DISCONNECTING SWITCH interlocked with the door.
• Sets of three FUSES type NH00 curve gG with a high breaking capacity, rated to protect the capacitor banks.
• Three-pole CONTACTORS rated for connecting the single batteries. Their peculiarity lies in the fact that the insertion contactors of the limiting resistors close in advance of the main contactors to limit the current peak at the insertion of the residual currents. The coils are 110Vac 50Hz (other voltages on request).
• Dielectrically oversized CAPACITORS of the “dry” type PRT.
• Internal connecting CABLES are flameproof type N07VK.
• Copper BARS size 30x5 mm.
• ELECTRONIC REGULATOR for automatic battery connection and cosφ control.
• Forced VENTILATION SYSTEM made with special, thermostat-operated fans installed on the top of the cabinet.
• Blocking REACTORS made with a core of top-grade magnetic plate with low-loss oriented grain.

Tuning frequency: 189Hz(p=7%).
On request: 134Hz(p=14%) -210Hz(p=5.67%).

Harmonic distortion in current allowed with continuous operation: 30%In at 250 Hz and 15% In at 350Hz.
Linearity: 2In.
Max harmonic distortion in voltage allowed in the network (THD%)=5%.

USES

The automatic freestanding equipment, ERAF series has been specifically designed for industrial power-factor correction for medium-large-scale operations in networks with harmonic distortion.
