- Product Introduction
Low-voltage reactive power compensation capacitors are core components used in low-voltage below 1kV distribution systems (typically at voltage levels of 380V 400V 440V 525V or 690V) for reactive power compensation. Their primary function is to provide capacitive reactive power to offset inductive reactive power, thereby improving the system's power factor.
In electrical networks, reactive power results in increased line currents for a given active power transmitted to loads.
The main consequences are:
● Need for oversizing of transmission and distribution networks by utilities
● Increased voltage drops and sags along the distribution lines
● Additional power losses
This results in increased electricity bills for industrial customers because of:
● Increased overall kVA demand
● Increased energy consumption within the installations
● Penalties applied by most utilities on reactive energy.
Reactive power management aims to optimize your electrical installation by reducing energy consumption, and to improve power availability. Reactive power management ensures better utilization of electrical machines, optimized electrical conductor sizes and reduced penalties from the utilities.
Model Meaning
Our capacitors dielectric use metalized polypropylene film to ensure excellent self-healing performance,and low loss(tanδ＜0.0002),A localized dielectric breakdown caused by overvoltage or overcurrent can rapidly self-heal and restore normal operation.We use epoxy resin as impregnent can ensure good sealing ability,vibration resistance and eco-friendly.
