Types Of Cable Glands And Their Applications
A cable gland is a device attached to the end of an electrical cable to secure that particular part of the device. Cable Glands permit its entry into the electrical equipment, enhancing the system with earthing, grounding, bonding, insulation, sealing, retention and strain relief. They are applicable for the processing ...
Types of Bimetallic Lugs and Specifications
The specifications of bimetallic cable lugs (aluminium barrel – copper palm) destined for installation on circular or semi-circular sectorial shaped, stranded, compacted aluminium conductors of power cables are highlighted in this blog. Bimetallic lugs prevent galvanic action due to dissimilar contact, primarily when a copper bus bar is connected to ...
Installation Of An ESE lightning Arrester
A lightning arrester protects the electrical network and the structures from lightning. When lightning strikes, it creates massive destruction and damages the equipment. A lightning arrester or a surge diverter protects the equipment at the substation. The lightning arrester bifurcates the abnormal high voltage to the ground without affecting the ...
Importance of Earth Mat in Substation
The earth mats or grounding mats bring the connection to the earth indoors. They usually connect through a conductor inserted within the ground port of an electrical outlet. They help in limiting the ground potential & protect against the faulty current. They are used in a place where the large ...
What is a Surge Protection Device?
Surge protection devices play a vital role in voltage fluctuations or variations. These fluctuations are the most common behaviours observed in any electrical system. Voltage change can vary from small voltage fluctuations for a short duration to a complete blackout for an extended period. When the voltage drops below the ...
Smart Meters in India ─ Types & Application
Smart meters record information on electrical energy consumption, voltage levels, current and power factors. They offer greater clarity on this information to the electrical service providers regarding electrical consumption, help with monitoring the system, and billing. They use advanced metering infrastructure (AMI) that differs from automatic meter reading (AMR.). They ...
Cable Glands ─ Need for Electrical Equipment and Switchgears
Cable Gland is the ‘mechanical cable entry device’ attached to the end of electrical cables and secures them to any piece of equipment. They are also commonly known as cable connectors, cable fittings, cord grips, or cable strain reliefs. Cable Glands are vital for terminating cables in harsh or hazardous ...
Installation of Cable Lugs
Cable lugs are electrical components used to safely connect wires and cable terminals to electrical equipment or terminate them. They are designed to easily and securely connect and disconnect electrical joints permanently or for maintenance. There are different types of cable lugs available for various electrical applications. They are essential ...
Distribution Boxes: Types and Functions
The distribution box serves as the load centre and distributor of electrical power. A distribution box ensures that electrical supply is distributed in the building, also known as a distribution board, panel board, breaker panel, or electric panel. It is the central electrical supply system of any building or property. ...
