- Power Control Center (PCC): PCC panels are used to distribute and control power in various industrial and commercial applications.
- MCC panels are specifically designed to control and operate electric motors used in industrial processes.
- Distribution boards: Are used to further distribute power to various loads within a building or facility.
- Lighting Distribution Board (LDB): LDB panels are specialized for controlling and distributing power to lighting fixtures.
- Sub-Distribution Board (Sub-DB): Sub-DB panels are smaller distribution boards used to distribute power from a main distribution board to specific sub-sections or areas within a building or facility.
Energy monitoring panels (EMPs) are devices or software solutions that monitor and track energy consumption in buildings, facilities, and industrial settings. EMPs provide real-time data on energy usage and performance, enabling users to optimize energy efficiency, reduce costs, and identify areas for improvement.
EMPs typically offer features such as:
- Real-time data visualization
- Historical data analysis
- Alerting and notifications
- Energy benchmarking
- Energy reporting and analytics
- Integration with building management systems
- Cost allocation
- Remote monitoring.
APFC panels are used to automatically control and maintain the power factor of the electrical system. Benefits of using an APFC panel include:
- Improved power factor: The APFC panel helps maintain the power factor (resulting in reduced reactive power consumption and improved electrical efficiency.
- Energy savings: By maintaining a higher power factor, the overall energy consumption is reduced, leading to lower electricity bills.
- Reduced voltage drop: Improved power factor reduces voltage drops and line losses, leading to better voltage regulation in the electrical system.
- Extended equipment life: A better power factor reduces stress on electrical equipment, leading to longer equipment lifespan and reduced maintenance costs.
MDC is a device that helps businesses and organizations manage their electricity demand. It monitors energy usage and can cut off non-essential loads when demand exceeds a set limit, helping to reduce peak demand and save money on electricity bills. MDC can also help to improve energy efficiency and reduce carbon emissions.
Here’s how a maximum demand controller typically works:
- Monitoring
- Setting a threshold
- Control
- Load management
- Alerts and data recording
Power transformers, distribution transformers, autotransformers, and OLTC transformers are the four main types of transformers used in the power system.
- Power Transformers: Used to step up or step down voltages in power generation plants, substations, and transmission systems.
- Distribution Transformers: This reduce high-voltage electricity to lower voltages for household and commercial use.
- Auto-Transformers: They have a single winding with multiple taps, which allows them to function as both step-up and step-down transformers.
- OLTc (On-Load Tap Changer) transformer: They have a tap changer that allows for the regulation of the transformer’s output voltage during operation.
High-tension breakers are used in high-voltage electrical systems to protect and control power distribution. There are several types, each designed for specific applications.
Some common types of HT breakers include:
- Air Circuit Breaker (ACB)
- Vacuum Circuit Breaker (VCB)
- Oil Circuit Breaker (OCB)
- SF6 Circuit Breaker
- Hybrid Circuit Breaker
An earth pit is a critical safety feature that provides a low-resistance path for electrical currents to flow into the ground in case of faults or lightning strikes. This grounding helps to protect electrical equipment, buildings, and individuals from electric shocks and damage caused by electrical surges.
Earth pits provide several important benefits in electrical systems such as:
- Electrical Safety
- Lightning Protection
- Equipment Protection
- Fault Current Diversion
- Compliance with Electrical Standard
- Power Quality Improvement
Lightning arresters (also known as lightning rods or surge arresters) are devices that protect structures, electrical systems, and sensitive equipment from damage caused by lightning strikes and electrical surges. They work by diverting the lightning current to the ground, where it is safely dissipated.
