6. FAQ
| 001 | Q | What is electrical switchgear |
| A | Electrical switchgear is a key component in electrical power systems and is used to both distribute electrical power and to selectively isolate electrical loads.
The switchgear is a switching device comprising of connecting or disconnecting switches, fuses or circuit breakers, protective and controlling devices which can be used to isolate electrical apparatus in faulty condition or during maintenance period, or to connect the same in desired healthy conditions. |
| 002 | Q | Do we need to monitor the switchgear conditions |
| A | Yes, Because switchgear distributes electrical current, heat build-up becomes an important characteristic to monitor. In particular, unexpected temperature rise at a particular location could indicate corrosion or some other type of defect. Thermal effects are especially visible in medium voltage switch gears used in distribution networks, where electrical currents may rise to few thousands of amperes. Thus keeping switchgears in proper condition over their long life becomes a critical issue. |
| 003 | Q | What are the main causes of arc flashes in industrial switchgear? |
| A | The main causes of arc flashes in industrial switchgear are: the application of tools to energize switchgear, deteriorated insulation on phase bus bars, and loose
electrical connections that overheat. These things can be prevented by proper safety measures and regular maintenance. |
| 004 | Q | What is the lowest voltage at which arc flashes occur? |
| A | 120 volts is generally considered the lowest voltage at which arc flashes occur. The voltage of industrial switchgear can exceed this voltage by hundreds of thousands of
times. |
| 005 | Q | What is Metal Enclosed Switchgear? |
| A | Metal Enclosed Switchgear is a switchgear assembly that encloses all necessary equipment and device in separate metal vertical structure (i.e MCCs, PCC), however they
each metal compartment are not separated from one another by metal barriers. It's used often with low voltage equipment. |
| 006 | Q | What is Metal Clad switchgear? |
| A | Metal Clad Switchgear is a switchgear assembly that encloses all necessary equipment and devices in one metal house, but compartments in this assembly is separated from
one another by metal barrier. When metal clad switchgear is used or assumed when MV switchgear is provided. |
| 007 | Q | Difference between Metal Enclosed Switchgear and metal Clad Switchgear. |
| A | Metal enclosed switchgear: Assembled with separate metal vertical section
Metal Clad Switchgear: Assembled in one metal structure.
MES: each compartment is not separated from one another with metal barrier.
MCS: each compartment is separated from one another with metal barrier.
MES: Frequently used in LV system.
MCS: Frequently used in MV System. When MCS is said MV Switchgear is assumed.
MES: All breakers and other switching devices are fixed type.
MCS: All breakers are withdrawable type. |
| 018 | Q | What is a transformer substation? |
| A | A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two
different transmission voltages. ... The word substation comes from the days before the distribution system became a grid. |
| 019 | Q | What is the main purpose of a substation? |
| A | The purpose of a substation is to 'step down' high voltage electricity from the transmission system to lower voltage electricity so it can be easily supplied to homes
and businesses through our distribution lines. |
| 020 | Q | What are the main components of a substation? |
| A | The substation is an assembly of the following major electrical equipments:
Electrical Power transformers.
Instrument transformers.
Conductors & Insulators.
Isolators.
Bus bars.
Lightning arresters.
Circuit breakers.
Relays. |
| 021 | Q | What is the purpose of a bus bar? |
| A | In electrical power distribution, a busbar (also spelled bus bar, or sometimes as bus bar or bussbar, with the term bus being a contraction, "for all") is a strip or bar of copper, brass or aluminium that conducts electricity within a switchboard, distribution board, substation, |
| 022 | Q | Breaker Box |
| A | A breaker box - more commonly known as an electrical panel - is mounted on the wall, usually in the basement of a home, and its purpose is to take in electricity
supplied by your power company and redistribute it throughout your home through electrical circuits. |
| 023 | Q | Circuit Breakers |
| A | These are large switches that act as safety devices to quickly shut off power to a circuit when there's too much electricity flowing through it. Typically, when that happens, the breaker will switch to the "off" position. Electrician's say that the circuit breaker for that zone has "tripped".
Most of the circuit breakers in your breaker box are single pole breakers. Some of the circuit breakers - the ones that look like two single breakers stuck together - are double pole breakers. These are for the large appliances in your home like your refrigerator, stove, clothes dryer, water heater, etc.
There are also some "special purpose" breakers designed to provide your home with extra protection from fire and electrocution. |
| 024 | Q | Service Disconnect Switch |
| A | This is where the electricity that powers your home comes into the electrical panel. The service disconnect - sometimes called the main breaker - looks like a larger
version of a circuit breaker and is usually found at the very top or bottom of the breaker box. In case of emergency, this is where you can turn off power to your home by rocking the switch to the "off" position. |
