ENERGY-S Operating Principle
At the heart of Energy-S technology is a small-power transformer, which works as an autotransformer with the transformation ratio on the verge of 1.
By way of switching-over the loaded transformer’s high-voltage winding without circuit break Energy-S selects the optimum operation mode depending on the conditions of outer power lines.

1. Normal voltage in the main
2. Boosted voltage in the main
3. Reduced voltage in the main
Use of ENERGY-S helps to save between
7 to 20 % of consumable electric horse power
by means of realization of optimum operation
for electricity consumers.

Switching on the ENERGY-S
There is no increase of electric current intensity during and after the voltage drop. This results in energy saving.

Power effects of ENERGY-S
Adjusting the capacity rate
Stabilizing the voltage
Compensating the branches
Reducing the harmonic distortions
1. Preventing:
Voltage surges Transmission congestions 2. Saving Energy
Benefits of ENERGY-S
11 / 22
Helps to extend the service life of electrical equipment and reduces cost of its maintenance and infrastructure
by protecting it from power surges and maximum simultaneous
demands at start.
Reduces power requirements by
creating system energy reserve that can be used
for other needs
Better quality of energy entering the equipment allows reduction of volumes of energy consumption
(minimal saving – 7 kWh)

Efficiency of ENERGY-S was confirmed by numerous test runs
Sberbank (Russia’s Largest Bank) Energy saving is 12,4%
Volvo Russia expert evidence Energy saving is 16,3%
Expert evidences of energy savings
Case-studies of ENERGY-S usage
Urban café
→ Need to provide power supply for a summer outdoor terrace without increasing power consumption quota.
Use of ENERGY-S made it possible to electrify the outdoor
terrace without increasing the power consumption quota.
Industrial enterprise
→ Need to increase production profitability
→ Need to extend service life of electrical equipment
Use of ENERGY-S helps to decrease amounts of payments for energy supply between 7% to 20% and extends the equipment service life by improving quality of energy supply.

Competitor products comparison
Majority of existing products of a similar kind solve ONE PROBLEM ONLY:
Reducing the reactive component of the power in the main
Improving quality of electric power by virtue of constant-voltage regulation
Filtering of the high frequency harmonics for current or voltage
ENERGY-S energy saving system is an integrated solution for ALL THESE PROBLEMS!
Plus, it offers possibility of remote monitoring and administration of power supply characteristics.
