What is an Industrial Electrical Power System?
An industrial electrical power system refers to the network of electrical components and infrastructure designed to generate, distribute, and manage electrical power within an industrial facility. It is engineered to meet the high demands of industrial operations, including heavy machinery, production lines, and critical control systems.

Key Components of Industrial Electrical Power Systems
Power Generation:

Generators: These are used as backup power sources to ensure continuity in case of a power outage from the main grid. Industrial generators are typically robust, high-capacity units designed to handle significant loads.
Transformers: Convert high-voltage electricity from the power grid into a lower voltage suitable for use within the facility. Transformers ensure that the electrical power is distributed at the correct voltage levels for various equipment.

Power Distribution:

Switchgear: Includes circuit breakers, switches, and fuses that control the distribution of electrical power. Switchgear protects electrical circuits by isolating faults and managing power flow.
Bus Bars: Conductors that distribute electrical power to different circuits within the facility. Bus bars are crucial for managing multiple power sources and loads.
Control Systems:

Programmable Logic Controllers (PLCs): Industrial computers used for automation and control. PLCs manage various operations by processing inputs from sensors and executing control commands.
Supervisory Control and Data Acquisition (SCADA): A system used for real-time monitoring and control of industrial processes. SCADA provides a central interface for operators to oversee and manage operations.
Protection Systems:

Circuit Breakers: Automatically disconnect circuits in case of overloads or short circuits, preventing damage to equipment and ensuring safety.
Relays: Devices that control the operation of circuit breakers and other protective equipment based on predefined conditions.
Energy Management:

Energy Meters: Measure the amount of electrical energy consumed, helping facilities monitor usage and manage energy costs.
Power Factor Correction: Devices that improve the efficiency of the electrical system by reducing reactive power and improving the power factor.
Functions of Industrial Electrical Power Systems
Power Supply and Distribution:

Reliable Power Supply: Ensures that all electrical equipment and machinery receive a stable and consistent power supply necessary for optimal performance.
Efficient Distribution: Distributes power throughout the facility, providing the correct voltage and current to various loads and processes.

Closed-circuit television (CCTV) cameras can produce images or recordings for surveillance purposes, and can be either video cameras or digital stills cameras. Video cameras are either analogue or digital, which means that they work on the basis of sending analogue or digital signals to a storage device such as a video tape recorder or desktop computer or laptop computer.

A short introduction to CCTV

CCTV stands for Closed Circuit Television, it is called this as unlike television it is not openly transmitted, it is built within a “closed circuit”. A modern CCTV system consists of CCTV cameras, CCTV Recorder (Network Video Recorder (NVR) is an IP based stand-alone video recorders that provides recording of IP video streams directly from the remote network cameras or network video servers that registered to NVR.), a display monitor and of course all these need to be connected together using cabling & accessories.

However, CCTV was developed and is still used primarily for surveillance/security of property, commercial and domestic, however it is being utilized for many other reasons, such as health & safety, sports activity recording, factory/industrial production monitoring and even bird watching.
