Firstly, High voltage control panel and switchgear are mainly use for the distribution of electrical energy connecte to various electrical networks. They include most substation equipment such as minimum oil circuit breakers. Bulk oil circuit breakers, air magnetic, SF6 gas insulated, vacuum and gas insulated switchgear. Secondly, This chapter focuses on high voltage (HV) switchgear. Cabinets can be design to have different configurations. This depends on the reliability, error rate and flexibility required. Manufacture High voltage (HV) switchgears are size according to a number of specifications: rated voltage, rated voltage, supply frequency withstand voltage and impulse voltage.
Electrical circuit protection relay
A switch is a piece of equipment use to open an electrical circuit by mechanical action, interrupting the flow of current without causing permanent damage to the equipment when used as design. A switch can be either a disconnected, an isolator or a switch. The term disconnect or isolator is use to describe a device that is design to manually open an electrical circuit under normal operating conditions. High voltage control panel and switchgear A circuit breaker (CB) is designe to open an electrical circuit in the event of overcurrent or fault conditions. This usually occurs with a trip signal from the protection relay.
Electrical power system
Switchgear is a general term use to refer to a series of switches, circuit breakers, fuses, etc. that are use in an electrical power system to control, regulate, and turn a circuit on and off. By controlling the circuit, the switchgear protects and isolates electrical equipment from power, allowing testing, maintenance and troubleshooting. We offer high voltage switchboard training because high voltage switchboards play a large role in power distribution and distribution system management. Proper installation, operation, and maintenance can save thousands of dollars, prevent equipment damage, and prevent accidents.
High-voltage switchgear
The purpose of this course is to provide a comprehensive overview of the issue of high-voltage switchgear for workers in electric power systems. High voltage control panel and switchgear The teacher will use lectures, visual aids and case history in the maximum possible exposure of high voltage distribution. Anyone working on or near power generation, transmission or distribution systems should attend this high voltage switchgear training course. In addition, supervisors, managers, safety personnel and those responsible for ensuring a safe working environment should attend this course. Switchgear equipment is essentially concerned with switching currents on and off under normal or abnormal operating conditions.
High breaking capacity
A lever switch with an ordinary fuse is the simplest form of switchgear and was use to control and protect lights and other devices in homes, offices, etc. For higher rated circuits, a high breaking capacity (H.R.C.) fuse is used in conjunction with a switch can be used to control and circuit protection. However, such switchgear cannot be used profitably on a high-voltage system (33 kV) for two reasons.
High-voltage system (33 kV) for two reasons.
• First, when a fuse blows, it takes a certain amount of time to replace it and then there is an interruption in customer service.
• Second, the fuse cannot successfully interrupt the large fault currents that result from high voltage system faults.
Low voltage devices
With the continuing trend of interconnection and the increasing capacity of power plants, the need for reliable switchgear has become of paramount importance. This is not surprising as it is added to the power system to improve reliability. When a fault occurs on any part of the power system, it must function to isolate the faulty part from the rest of the circuit. Burraq Engineering solution is an Engineering instrument that provides High Voltage control Panel and Swichgear Training courses in Lahore. Commonly used low voltage devices include oil circuit breakers (OCBs), air circuit breakers (ACBs), fuse disconnect units (SFUs), disconnects, HRC fuses, earth fault circuit breakers (ELCBs), residual current protective devices (RCCBs). & RCBO), Miniature Circuit Breakers (MCB) and Circuit Breakers (MCCB) etc. i.e. all the accessories required to protect the LV system.
