概述

Save costs with intelligent technology.

Highlights

• More efficiency through lower energy costs

• Efficient power system dimensioning as a result of low reactive power

Cost-efficient overall system

In a power system, reactive power is caused by inductive linear loads such as motors, transformers and reactors, and inductive, non-linear loads such as converters, welding e, arc furnaces or UPS systems. The sections for central reactive power compensation relieve transformers and cables, reduce transmission losses, and thus save energy.

Optimized power system

In order to improve energy or power system , appropriate components can be integrated into the switchboard to compensate for reactive power, resulting in a lasting reduction in energy costs. The components have to be adapted to meet special requirements.

Components

4RB2-4RB8 capacitors

Power capacitors generate the leading reactive power required to compensate for the lagging reactive power. The design ensures a high inrush current capability, a long expected service life as well as reliability. 4RB capacitors are self-healing and provided with an overpressure disconnector.

4RB9 reactive power controllers

The modern PF controllers are based on microprocessors. The microprocessor analyzes the signal from a current transformer and generates switching commands to control the contactors that add or remove capacitor stages. The intelligent control system ensures an even utilization of the capacitor stages, a minimized number of switching operations and an optimized life cycle of the capacitor bank.

3RT26 capacitor contactors

Capacitor contactors are special contactors used for switching capacitive loads. They are based on the field-proven 3RT2 basic units and have precharging resistors that are decoupled again following attenuation of the switch-on peak current. Capacitor contactors are often used for switching power contactors in reactive power compensation systems and are suitable for solutions with and without reactors.
