Common Questions: Answers to Energy Optimization

What is the ESO system?

The ESO system is a dynamic control solution for inductive loads that continuously adapts to fluctuations in your grid. It contains powerful capacitors and a control system that improves voltage quality, reduces losses, and optimizes energy efficiency.

Why do I need the ESO system?

The ESO system stabilizes the voltage, can reduce grid losses, smooth harmonics and minimize transients. As a result, it can extend the service life of your devices and increase operational reliability.

How long has the ESO system existed?

The basic technology of the ESO system is compensation. This technology has been used worldwide, primarily in industry, for more than 50 years. The ESO system was specially designed for small and medium-sized companies and has already been used successfully hundreds of times by satisfied customers.

Can the ESO system reduce my electricity costs?

Yes, the ESO system can help to reduce energy costs by improving power quality and reducing grid losses. However, the savings depend on the individual grid conditions and average up to 12%.

Will I save money with the ESO system even if I don't pay reactive power costs?

Yes, even if you don't receive a special bill for reactive current, you can still save money by using the ESO system. By reducing network voltage faults and the associated increase in voltage, you reduce energy consumption and thus your energy costs. In addition, improved voltage quality (no harmonics, no high voltage pulses and the resulting reduced line voltage value) contributes to an extended lifetime of your electrical machines, devices and lighting technology and thus saves additional costs.

How is the ESO system installed and what are the costs?

Installation can be carried out by local certified electricians in accordance with our instructions. The installation costs are separate from the purchase price of the ESO system and vary depending on complexity and location. Typically, the cost per module is between €700 and €900.

Does the ESO system also work with frequency converters?

A frequency converter and the ESO system fulfill different functions: The frequency converter controls the speed of motors, while a compensation system such as the ESO system contributes to power factor correction. In some cases, the combination can be useful to keep the power factor stable. Whether both systems are needed together depends on the specific requirements of your system.

What is the difference between active power (kWh) and reactive power (kvar)?

Active power (kWh) is the energy that appliances actually consume in order to perform work. The reactive power (kvar) does no work, but circulates in the grid and can cause losses. The ESO system can help to minimize these losses.

Can the ESO system also reduce active power (kWh)?

Yes, the ESO system can also reduce the active power under certain conditions by optimizing the grid conditions. The actual effect depends on the respective grid structure and the available devices.

What causes losses in power grids?

Grid losses are caused by resistance in lines and transformers, which can lead to voltage drops and heat losses. The ESO system can help to reduce these losses and thus improve efficiency.

What are harmonics in power grids?

Harmonics are unwanted frequencies in the grid, usually caused by non-linear loads (e.g. electronic devices), which can cause efficiency losses and possible device damage. The ESO system can help to reduce harmonics and improve energy efficiency.

What are interference pulses in power grids?

Interference pulses are sudden voltage peaks or fluctuations that can be caused by external factors such as switching operations or faulty devices. They can affect the service life of systems and lead to malfunctions. The ESO system can help to cushion these interference pulses and thus improve the stability of the grid.
