MR466E Capacitor Bank Didactic Equipment Didactic Equipment Demonstrational Equipment Electrical Engineering Lab 1. Equipment introduction 1.1 Overview This low-voltage reactive power compensation box is suitable for rural and urban distribution networks and internal distribution networks of industrial and mining enterprises. Power compensation; It can also be used for on-site reactive power compensation of low-voltage power grids and power equipment in factories, mines, petroleum, chemicals, railways, ports and other industries. Using single-chip microcomputer control technology, the sampling signal measurement system is a three-phase analog or three-phase electronic type. The measurement and switching thresholds can be set by the user or controlled by fuzzy logic; the work is stable and reliable; the actuator that controls capacitor switching is dedicated to switching capacitors. The capacitive non-contact switch is suitable for situations where the load changes frequently. Using this device brings the following benefits: Improve the power factor of the grid without returning reactive power Stabilize voltage and improve distribution voltage quality 1.2 Features •Capacitors: 4 cylindrical laminated polypropylene dielectric, 3 1 kvar capacitors and 1 3 kvar capacitor. • Contactors: 4 20 amps. •Controller: Automatic.
