In India, voltage classifications are done by Low Voltage (LV) and High Voltage (HV. If the voltage goes above 1100 volts then it is called High Voltage (HV) or High Tension(HT). Below are some examples: 6.6 kV11 kv33KV On the other hand, anything lower than 1100 volts is considered Low Voltage (LV), which may consist of single-phase AC voltage at either 230v or three phase with an expected range from 415 to about approximately up-to around 440V. Based on this classification, electrical panels are also categorized as HT panel and LT Panel.
High Tension (HT) Panels
To begin with, what is an HT panel and why it seems to be a very useful tool? The supply voltage of 11 kV and above is used for HT panel, i.e., HT Panel if the Same12/24 Volt Rooms are Required 6. Major function of HT PANEL is to receive incoming high voltage supply from transformer (HT) and as shown in fig 2 these are part of the main distribution panels, backside one can see them with a colourful pattern. Vacuum circuit breakers serve to protect the downstream devices connected across HT panels.
Low Tension (LT) Panels
Secondly, LT panels which are for operating voltage less than 1100 volts. First of all, coming to the main LT panel it is also known as Power Control Center (PCC) object Mapper Word Post Mapping FT Scenario: HT Supply comes into the HT Panel and hop through a transformer that decreases its voltage to step down way it now goes inside the Main LT Panel. This stepped-down supply is then distributed by the Main LT Panel to different feeders for other distributions.
Automatic Power Factor Correction (APFC Panel)
The power factor is kept in control with the help of an APFC panel which helps bettering its quality and efficiency. The unit includes power factor correction banks which help in decreasing the electricity bills while improving its power efficiency.
PDB Panels are Power Distribution Board
Level 2 Distribution: Power Distribution Board (PDB)/Main Distribution Board For example, in any campus having the no of building there we are transferring Main supply through HT panels & Transformers and step down with secondary side connected to the Main LT Panel. The supply then reach different buildings through the feeders, and in those buildings PDB panels take care of distributing it to various floors.
Motor control center (MCC) panels
MCC Panel Motor Control Center (MCC) panel is also one of the interesting panels as it controls many motors drawings lot more current that an MCCB releases. MCC panels automate the operations of motors and are thus employed in industries where a large number of motors are put to use. It has the various motor starters and components to manage though some of them for a point control so mekitar an operation.
ELDB Panels (Emergency Lighting Distribution Board)
The last one is the Emergency Lighting Distribution Board(ELDB) panel or simply known as Emergency Panel. It’s responsible for keeping an energy backup obtainable if the principle one fails. The panel automatically switches over to backup power, keeping things like connected devices, lights and even your refrigerator humming along.
Automatic Main Failure Panels (AMF):
Usage : The AMF panel is installed between the diesel generator and the main power supply panel. In case of main power failure, it automatically starts the diesel generator and transfers the load to it, which greatly reduces the period of time without power (Meaning from minutes to seconds)
In conclusion: understanding the different types of electrical panels and how they operate helps to realize the complexities and the importance of an electric distribution system in different environments. Industrial one, a large campus, or an emergency one; each panel has its own function and provides a reliable and efficient energy source. For those looking for quality panels, an electrical control panel manufacturer in Kolkata can offer customized solutions to meet specific needs.
