Reducing the consumption of electrical energy by an enterprise serves as one of the criteria for assessing the final competitive cost of manufactured products. It is known from the course of school physics that the electricity supplied to the consumer should be considered as:
- Active energy - used to maintain (start, operate) electrical equipment.
- Reactive energy - spent on creating electromagnetic fields and pulses in electrical devices (not for their intended purpose), but paid based on meter readings.
Special reactive power compensation units include basic devices such as capacitors, as well as controllers, contactors and surge protection systems. They are able to correct the power factor in different phases of electrical energy consumption and thereby reduce reactive losses arising during its transportation through the network (losses can reach 30%).
The principle of operation of condensing units
The principle of operation of capacitor units compensating for reactive power is based on the possible use of the principle of dynamic (switching) compensation using capacitors and one of 2 types of additional devices:
- Contactors - equipped with an electromechanical relay, fairly easy to use and maintain.
- Thyristors - perfectly cope with the task of reactive power compensation in networks with increased voltage surges. The system is considered quite expensive, but very effective.
When energy-intensive equipment (electric motors, generators) is started up, compensating installations begin to actively absorb and accumulate reactive energy, giving it in doses into the network, thereby increasing the total (useful) active power.
You can get more detailed information on the types and technical parameters of condensing units using the official website of the company that designs them, as well as production using advanced high-tech equipment. In the online catalog of the resource, serial models are presented, at the same time, the company provides for the option of manufacturing equipment according to individual customer parameters.
