About SYSTEM ELECTRIC
Founded in 1975, SYSTEM ELECTRIC Power Quality GmbH is an internationally active system provider for reactive power compensation, voltage quality improvement and grid relief. The company manufactures ready-to-connect, automatic compensation systems in modular and compact designs, capacitor switching modules, dynamic compensation systems, reactive power controllers (CONDENSOMATIC), thyristor switching modules (CONDENSOTRONIC), capacitor contactors, filter circuit and detuning reactor coils made of copper and aluminium, self-healing LV power capacitors in dry technology, and medium-voltage compensation systems for 1–12 kV. The products are developed for grid voltages from 0.23 to 10 kV, built in cabinet systems with system widths of 600 and 800 mm, and are accompanied on a stationary basis by maintenance, grid analysis, measurements and commissioning. Customers include industries such as steel mills, chemical processes, solar installations, cement plants, oil refineries, pipelines, wind turbines, shipboard power systems, drilling platforms, cable cars, port facilities, hospitals and subways. Reference customers include, among others, KUKA, KSB, Flughafen Zürich AG, Saarstahl Völklingen and the Swiss Federal Railways. The company is certified to DIN EN ISO 9001:2015, is a member of ZVEI and distributes its products via representatives and projects worldwide.
