It is undesirable to turn on simultaneously powerful consumers of electricity such as an electric stove, oven, microwave, washing machine, iron, floor heating, boiler, electric kettle, air conditioner, electric fireplace, vacuum cleaner. Each of them consumes about 1 kilowatt of energy. So for example, when one of these electrical appliances is turned on, the loss of electricity will be, for example, 10 watts, when two are connected, it is already 40 watts, and when the lights are on and all eleven listed electrical appliances are already 1440 watts! That is, losses increase quadratically from the number of simultaneously turned on powerful electrical appliances. In addition to a catastrophic increase in losses in the power grid, this can lead, at best, to shutdown of the machine, and in the worst case, to burnout of electrical wiring or fire.
Every year the number of powerful appliances per apartment is increasing, and although the average consumption remains about the same, due to the use of more energy efficient lighting, computers and televisions, the peak consumption increases many times over. Therefore, while turning on several powerful energy consumers at the same time, remember that your neighbors can do the same, and if your in-house networks were designed many years ago, they may not survive. And the norms of network design have not changed for a long time and today’s realities have not been taken into account.
The analytical module of the BALANCE metering system allows calculating phase-by-phase losses on in-house networks and issuing recommendations for the optimal distribution of consumers by phases, as well as identifying consumers for whom it is desirable to supply two or three phases (for example, to divide the consumption of the kitchen and the rest of the apartment). This allows you to significantly equalize the loads on each of the phases and increase the safety of intra-house networks.
For each consumer, along with the consumed electricity, his contribution to the losses of in-house networks is calculated.
For the electricity supplier, this is a significant increase in income. A simple calculation shows that when installing the BALANCE metering system and distributing loads according to the recommendations of the analytical module, losses can easily be reduced by a third – from an average 12% to 8%. With an average electricity bill of about 300 lei / month, the gain is about 12 lei / month. With the average cost of data transmission equipment (with connection to the radio module of three apartments) about 400 lei / apartment, the equipment pays for itself in 33 months, i.e. in less than three years.
The analytical module for detecting theft and faulty metering devices (based on the correlation of consumption profiles and imbalance profiles) can further reduce losses by up to 4%.
To monitor the safety of in-house networks, an association or a power supply company can additionally install sensors:
– Phase voltage loss sensors;
– Voltage sensors on the neutral wire;
– Voltage sensors on phases;
– Sensors for arcing wiring (poor contacts).
The FRESH platform – organically complements the capabilities of the BALANCE system – allows you to track the position of objects, take into account the availability of objects, take into account the working hours of remote employees and use sensors built into a smartphone.
