Product description
Destination:
It compensates for the reactive electrical energy consumed by the inductive receivers to obtain a power factor cos δ› 0.92
Features::
• ensures the engagement and disengagement of the adjustment stages in manual or automatic mode
• ensures the short-circuit protection of the adjustment steps made with fuses
Advantages::
• reduces active power losses (an installation operating with a cos δ = 0.7 has active power losses twice as high as an installation operating with a cos δ = 1)
• reduces the reactive energy bill
• simplicity of the assembly
• low maintenance costs
• possibility of expansion
• it improves the local voltage level by producing local reactive power, which leads to increased efficiency
• increasing the active power loading capacities of energy installations
• does not require specialized operating personnel
• the specific cost is lower than that of synchronous compensators in RON/kVAR
• reduces disturbances on telephone and television lines, due to the decrease in deforming power
• ensures the operation in steps, to achieve an optimal compensation
Constructive characteristics:
• the metal cabinet ensures a degree of protection IP 30 (indoor version) and IP 54 (outdoor version)
• devices (capacitors, contactors, fuses) are mounted on counter-panels, crossbars and/or metal drawers
• painting is done with powder, in an electrostatic field
Power factor compensation installations are equipped with indigenous or imported equipment (Vishay USA, Roederstein Esta division from Germany)
Technical characteristics:
Normal reactive power 25… 400 kVAR
Number of adjustment steps 3-12 steps
Nominal usage voltage 400 / 230 V a.c.
Nominal insulation voltage 660 V a.c.
Nominal frequency 50 Hz
The capacitors is part of the ISO 9001 quality system with the following performances:
• sunt ecologice
• it does not present a risk of explosion, it disconnects itself
• dielectric with regeneration, biodegradable
• burning point > 300 °C
• lifetime > 100,000 ore de lucru
• low losses (< 0.25 W/kVar)
• small dimensional weight
The contactors are specialized for capacitive load coupling and are guaranteed for 100,000 engagements. They are provided with auxiliary and resistant contacts that precharge the capacitors before closing the main contacts.
The regulators with microprocessor have the following characteristics:
• digitally display the power factor
• it automatically determines the parameters of the compensation installation, through successive couplings of the stages during commissioning
• it works according to a program that optimizes and counts the number of engagements on each step
