Tariff switching device
The tariff switching device (TSG), also known as the tariff switch , is used to remotely control consumers in the supply network of the energy supply company as part of the load control ( demand side management ), thus / as well as to switch between high-price tariff and low-price tariff (HT / NT ) for electricity meters . If no double tariff meter is provided , the heavy consumer (s) will be switched off during the validity of the HT tariff, by the tariff switching device and, under certain circumstances, also by the corresponding power contactors, or completely, galvanically , disconnected from the mains with the power contactors .
The popular ripple control receiver is such a tariff switching device. However, some energy supply companies no longer send ripple control signals and use, for example, a static switchover with a timer . This is called as a generic term of a collective switching device, as well as other techniques as timers or ripple control receiver, for example radio ripple control receiver , GSM receiver, modem , DSL can be applied, etc. and in the future probably replace the aged ripple control technology.
The great advantage of controlling the tariff switching device via modem, GSM receivers, DSL and other Internet connections is the possible selection. Individual heat pumps , hot water boilers or night storage heating systems can be switched on or off by the utility company depending on the electricity supply and load profile in the respective network section, which simplifies the exact control of electricity consumption and the load on the transmission networks .
Due to the immense increase in fluctuating electricity generation by photovoltaic and wind power plants, load control is expected to become increasingly important, along with other measures.
