Voltage management is a collective term for a variety of technologies, such as voltage optimisation, voltage control and voltage stabilisation, according to DIN IEC 60038 (230V +/- 10%).
If electric consumers are supplied with a higher voltage than is necessary for them to function properly, the power loss increases, thus power consumption and its cost.
Greater CO2 emission are created than necessary, and these have a harmful impact on the environment.
*According to information from the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, an average of 574 g of CO2 were released in the Federal Republic of Germany in 2007 for the production of one kWh.
Constantly growing power costs and increasing CO2 emissions make a responsible approach to energy consumption necessary. According to IEC 60038, energy suppliers may provide supply voltage of 230V +/- 10% (207V to 253V). Within these tolerance limits, all electric consumers must operate to optimum efficiency, according to IEC 60038. When our RENECOST® systems are used, all electric consumers are supplied only with precisely the stabilised voltage that they actually need in order to comply with all standards. This leads to reduced power input and lower power consumption.
On average, Schuntermann GmbH achieves power savings of 8% to 15% for its customers, with a return on investment between two and four years, including one-off installation. Furthermore, stabilised voltage leads to longer service lives for electrical equipment. The costs for maintenance and repair are therefore lower. By reducing power consumption, CO2 emissions decrease, which makes a positive contribution to environmental protection. Schuntermann GmbH has manufactured well above 4,000 systems for voltage stabilisation which it has successfully installed and put into operation around the world.

voltage control without replacement of existing local network transformer
Voltage control on the low voltage side – without replacement of existing local network transformer
The constantly growing number of renewable power generators – photovoltaic systems in private households, small combined heat and power units and wind farms – is leading to increasingly decentralised supply into the existing network, with the result that power generation and consumption are no longer in balance.
Due to the external supply of renewable energies, the supply voltage in the low voltage network may only rise by a maximum of 3% at the feed point before the limits stipulated by standard IEC / EN 60038 are exceeded..
Energy suppliers are legally obliged to prefer the supply of renewable energies. This means that, depending on the weather situation, there can be significant voltage fluctuations in the local network, with the result that supply is no longer possible in the event of excessive voltage.
Optimised adjustment of system voltage using the Schuntermann control systems – REGETRA – is possible at every point in the mains line. This increases the voltage swing from 3% to 11% and thus increases the window for the supply of renewable energies significantly. The costly replacement of the existing local network transformer can be avoided in most cases, and thus the costly dismantling of network infrastructure that would otherwise be necessary.
NEREKON systems from Schuntermann can be positioned wherever the customer wishes in the network.
