Compensations are used in electrical systems to ensure that the phase shift between voltage and current resulting from inductive and capacitive effects is close to zero. Compensation is a measuring device required and used to regulate the power coefficient in the facility. In the electrical system, the reactive power needs of the loads are determined by compensations using certain techniques. As Bartek, we are always with you for your compensation panel needs.
Compensation Panel
Compensation is a tool used to monitor the continuous increase in power in electrical networks today. Thanks to compensation, reactive loads are kept at the required level and any electrical problems are prevented. With compensation, reactive energy is provided to the consumer at the lowest level and its capacity is adjusted in this way. Compensation panel is used in all compensation operations. Thanks to the compensation panel, the power factor in the facility is regulated and the necessary devices and measuring instruments are also located in this panel.
How to Make Compensation?
To perform the compensation process, a fuse, current transformer, shunt reactor, capacitor or reactive relay is needed. To regulate the power number, the reactive power components become smaller and thus the circuit current does the same job with a smaller current. While these processes are taking place, there is no change in the active current. The reactive current, which was excessive before compensation, decreases thanks to compensation and the circuit current also becomes smaller. Compensation systems recommended for use in electrical systems are necessary to balance electrical power and use it in sufficient amounts. Reactive power generators used in electrical systems continue to produce power as needed.
Why is compensation done?
If compensation is not made due to any situation, losses occur in the networks and more current occurs in transmission lines and cables. For this reason, large voltage drops occur one after the other. Energy carrying capacity also decreases. As reactive power is consumed in facilities and businesses, the power coefficient decreases and the facility operates below the nominal capacity. Then, a voltage drop occurs in the facility and losses increase. The main problems caused by low reactive power value include heating in cables, heating of transformers and reactive penalties. When consumers set up compensation themselves, it is sufficient to use fixed capacitors. At the same time, all compensations used must comply with the regulations.
What are the Compensation Types?
Compensation types include individual compensation, group compensation and central compensation. Apart from these, there are Shunt Reactor Compensation, Static Contactor Compensation, Driver Compensation and Medium Voltage Reference Compensation. In individual compensations, the reactive power source, such as a motor or lamp, is connected in parallel with the receiver. In group compensation, it is used to compensate load groups that are activated and deactivated with the same contactor or switch.
Central compensation is a system in which the power of compensation is adjusted according to the loads in the circuit and the type of load. Individuals or institutions need to choose the most appropriate type according to the place of use.
