In industrial electric power systems, current and voltage rise and fall with the frequency of the source of power. Whether the current and voltage rise together varies on the characteristics of the electric load, and for this, there are three types, incandescent lighting, heating elements, and resistive loads. Inductive loads are associated with the power to spin the motors and the creation of magnetic fields, which causes changes in the voltage. In this ratio, the voltage leads to current is known as the factor for power.
The third type is the capacitive loads, and this is the opposite of inductive loads. Capacitive loads consist of the energy stored in devices, like capacitors, and bring changes in the voltage. Capacitive loads are less common but are becoming widely used with the advancement of complex electronics. Let’s know more about Capacitive loads.
What is a capacitive load bank?
A capacitive load bank offers the same effect as other types of load banks. It provides a load to a circuit and removes the electrical energy to initiate a particular application. However, capacitive load banks use capacitors, which have two operational surfaces to store the energy in the electric platform.
These load banks use industrial capacitors. Their controls allow the system operators to identify the right amount of load needed for the test. For most processes, capacitive load banks are used with resistive load banks to balance the power factor.
Common applications of a Capacitive Load Bank
- Correction of power factor– ups load bank is often used to balance the power factors in industrial platforms, capacitive load banks are joined with circuits to prevent inductive power load from lighting, machines, and compressors. This moves close to one power factor, and it’s known as unity. A closer unity is more economical and efficient.
- Power system development and research– research and development facilities often have pre-installed capacitive load banks to test the power systems and get used to the fluctuations in the load. Special types of load profiles are applied for specific times. If a system adapts to the changes in the load, proper testing can take it to the next level. A capacitive load bank is common in marine testing because inductors like batteries and inverters are used in marine work processes.
Difference between inductive and capacitive load bank
- Inductive load bank– inductive load banks transform the current into a magnetic field. The reactance resists the change in the voltage, making the circuit lag in current. Examples of devices that produce inductive loads are chokes, transformers, and motors. When this is used with resistive load banks, the inductive load bank reproduces commercial loads that consist of chokes, transformers, motors, heating, and lighting. Which means you can evaluate the performance of the power system, including the switchgear, conductors, voltage regulators, and generators?
- Capacitive load bank– capacitive load bank charges and releases energy. The reactance resists the alteration in the current, which causes the voltage to lead the current. This is similar to the inductive load bank in its purpose and rating. However, if the load is light, it supplies switched-mode power, which leads to a power factor.
Load banks are important for testing the power capacity of data centers and other areas where power fluctuation is a constant thing. To buy load banks you can get in touch with a reputed supplier.
