Panels for power factor compensation

Panels for power factor compensation

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


 

Usage conditions:

Ambient temperature -30°C...+40°C
Relative air humidity max 95% at +20°C
Maximum altitude             2000 m
Lifetime             20 ani
Mounting location            indoor/outdoor
Degree of pollution             3
