Neutral Grounding in Medium Voltage Networks Security of energy supplies in medium voltage networks gets mare and more important in the liberalized energy market. Single pole faults should not lead to energy supply interruptions. We offer: Planning, consulting, calculation / design and construction of neutral ground treatment plants in medium voltage networks. Especially active fault protection such as resonant-grounding (RESPE) incl. earth fault detection by admittanz method. Furthermore, the design and construction of short time grounding systems (KNOSPE), as well as low-impedance neutral grounding (NOSPE). Our newest product is the “Phase Grounding” which was developed in order to relief the fault location during erth fault.
