When you visit an industrial work site especially in the load center, two types of power distribution are found namely HT panels (High Tension) and LT panels (Low Tension). The systems are important for managing different electricity powered devices in an industrial environment. Let’s dive into what each of these does, how they are different and see them work together specifically in the sectors such as control panel manufacture in Kolkata.
Ht Panels : High Tension Power Distribution
The voltage levels at the which these HT panels operate are high as is evident from their name i.e. High Tension Panels and so they find use for 11 kV supply lines etc. These vacuum circuit breakers (VCBs) are used to control and protect the high-voltage circuits. In case of large motors (5000 kW motor or 1500kW), the power is directly given through HT Panels and in only few industries they require high amps >125A. So whether you have an 11 kV supply, HT panels will see to it that all these motors are run in a more protected and optimized manner.
Here the voltage levels are specified for HT motors, which can be different in various industries like 6.6 kV or 11 kV etc However, the vice-versa function is still intact; HT panels support a direct feed to big motors or transformers.
Low Tension Power Distribution-LT Panels
LT Panels carry power more in Low voltage form -usually around 415V- and there are various forms within these type of panel as well; PCC (Power Control Centre) & MCC (Motor Control Center).
PCC (Power Control Center)
Power control in an industrial setting is managed by the PCC panels. Commonly used PCCs are designed for 415 volts and fitted with Air Circuit Breakers (ACBs) Panels. Key functions of a PCC include:
Draw power from the local incoming feeder (generally coming from a distribution transformer).
What do you mean by Quote Unquote – You are not allowed to distribute the power for multiple MCCs or large motors (200 kW motor like Compressor).
Other MCC incomers are fed by various ACB in PCC and each one supplies power to some individual motors. For example, an ACB is in the ON condition accepts that a motor or MCC to operate and control different types of industrial applications.
MCC (Motor Control Center)
MCC – Motor Control Centre is use for controlling the operation of more than one motor. MCC caters power of PCC and distributes to various motor feeders. They can control equipment like belt conveyors, fans, dust collectors or pumps.
Within the MCC, this bus is charged and then power to individual motors as required.
Additional Types of LT Panels
Other important LT panels along with PCC and MCC
PDB (Power Distribution Board): It is used to distribute power at different locations like the floors of a building. Example: if one industry has welding or chipping on two floors then PDB will provide power to the required sockets in each floor.
MLDB (Main Lighting Distribution Board): Basically it is like PDB but as per name we can understand that it provide power supply to all lighting circuit. It supplies power to lights in areas like staircases, rooms, or outdoor spaces.
Other Panel Types
APFC Panels (Automatic Power Factor Correction): These panels make the electrical system more efficient by increasing its power factor.
DG Panels (Diesel Generator Panels): Diesel generators with these panels regulate power; use it when there is no supply from the primary source.
Electrical Control Panel Manufacture in Kolkata
In case you are looking for electrical control panel manufacturer in Kolkata, it is essential to understand that the city has some of the top manufacturers catering exclusively with HT and LT panels. These industry-specific solutions guarantee that companies in the industries served are able to have custom-made power distribution systems created for their unique operational needs. From PCC panels to MLDB, MCC &PDB Panels— you can easily trust the Kolkata-based manufacturers on providing high quality and unerring electrical control panels.
For effective industrial operations, it is important to be aware of different types of electrical panels whether they are provided for controlling high-voltage motor or low-voltages such as PCC, MCC, pdb and mldb control & distributed power respectively. The circuits of these panels are made according to industrial norms by well-established manufacturers in Kolkata that ensures reliable and safe power distribution across the industries.
