What is the RCBO? RCBO is basically known as residual current circuit breaker with overcurrent. And residual current circuit breaker with overcurrent is a kind of low-voltage circuit breaker. RCBOs are used to protect against earth leakage fault currents with over currents. RCBO has extra protection against overload and over current. And it mainly uses a microcontroller and it can also be called as a combination of MCCB and RCCB. That is why; It is more useful than the RRCB; Because RCCB does not provide protection against overcurrent. Some RCBO have indicators to indicate any earth fault. This feature is very useful as it helps the engineer quickly in troubleshooting.

What is the RCCB? RCCB is basically known as residual current circuit breaker. Residual current circuit breakers are a type of low-voltage circuit breaker. RCCB is used to protect against earth leakage fault current. RCCB have small current ratings, typically up to 160A. RCCB provides protection against lightning shock. This is because the role of the RCCB is mainly to detect earth leakage and trip the circuit if detected. There is a test circuit operation to check if the RCCB is working.

What is MCCB? MCCB is basically known as Molded Case Circuit Breaker. And Molded Case Circuit Breaker is a type of low-voltage circuit breaker. MCCB are used for higher power requirements like industrial or large commercial applications. The MCCB can be used up to 2500 A. This makes it possible to use MCCB in large applications. Interruption rating of MCCB can go up to 200000 A. MCCB have various tripping functions such as continuous ampere, long time delay, short time pickup, short time delay, instantaneous pickup and ground fault pickup. These are adjustable trip functions, which means you can set trip parameters to suit your needs; Thus providing the user with more flexibility to design the circuit. MCCB is enclosed in a molding or housing of molded material and hence known as molded case circuit breaker.

What are MCBs? Basically MCB is known as miniature circuit breaker. And MCB is a type of low-voltage circuit breaker. MCBs are used for household purposes or for low power applications such as small electrical panels. MCB can be used up to 100 A only. The MCB has an interrupt rating of up to 18000 A. Class 3 MCBs are very popular these days due to their fast tripping capability and their minimal energy loss.

What are the types of circuit breakers? Basically a type of circuit breaker  MCB (Miniature Circuit Breaker) MCCB (Molded Case Circuit Breaker) RCCB (Residual Current Circuit Breaker) RCBO (Residual Current Circuit Breaker with Overcurrent) MPCB (Motor Protection Circuit Breaker) VCB (Vacuum Circuit Breaker) SF6 (Sulphur Hexafluoride) Circuit Breaker Oil Circuit Breaker

What is Circuit Breaker? Basically, circuit breakers are an essential part of electrical circuits. It is a device that is used as a protective switch to pass the current that is checked for tripping condition. When it detects a trip condition, the circuit breaker opens its contact and isolates the input and output voltages from contact with each other. Hence, its basic function is to interrupt the current flow after the fault is detected. It stays open until the user resets the trip.

What are all aluminum conductors? Basically AAC (All Aluminum Conductor) is an electrical conductor made completely of aluminum. It can be seen as a stranded set of conductors, stacked one upon the other. Aluminum is a good conductor of electricity, and being such a bulk conductor material, AAC has the best conductivity. Also, it is extremely corrosion-resistant. But, with such a large amount of aluminum, its weight increases relative to its moderate strength and it starts to bend. Hence these types of conductors are used for shorter distances and where grid towers are close. Because, even though it will run for only a short distance, it will provide an excellent current transfer.

What are the types of overhead conductors? Basically the most common types of overhead conductors are listed below. AAC (All Aluminum Conductor) AAAC (All Aluminum Alloy Conductor) ACSR (All Aluminum Conductor Steel Reinforced) ACAR (Aluminum Conductor Alloy Reinforced)

What is Overhead Cable?  Basically, long lengths of electrical cables running through power distribution and transmission grids. It is seen everywhere around us. These cables bring electricity to your home. They are called overhead cables. An electrical cable consists of two parts, conductor and insulator. A conductor is a material inside that allows electricity to pass and an insulator is a material that prevents electricity from passing through it.

What are the types of switching mechanism in ATS?  Basically, there are two types of mechanisms that work in ATS – open transition and closed transition. Free transition means break-before-make. Before changing any power supply connection, it will first open the existing connection and then connect to another one. A close transition is a make-before-break. Before breaking any power supply connection, it will first switch to the new connection and then break the previous connection.

What is Auto Changeover Switch? Basically you have two sources of power – primary and secondary. Earlier, when the main power supply went off, the operator himself would go and switch on the secondary power supply. This would take time, especially if it is far from a power source. To solve this problem, auto changeover switch was started to be used. As the name suggests, auto changeover switches are used to automatically switch power between primary and secondary sources. If the mains supply shuts down or fails, this switch will automatically connect the load to the secondary power supply. On resumption of mains power supply, this switch will switch the load back to mains power supply. It works in the same way as a relay. Therefore, this automatic switch acts as a very important component to provide instantaneous power supply. An auto changeover switch has a microprocessor that is programmed to control the switching of the power supply. At one end, it senses the main power supply and a

What is Transformer Bushing? Basically a transformer is a device which is used to step up or step down the voltage as per requirement. Transformers are required in power transmission and generation stages, they involve high voltages. Since the transformer works at very high voltage, it is also necessary to take care that it functions properly without any leakage or damage. Now, it is worth noting that there is one very important factor in helping the transformer to function properly; That is its bushing. Without a bushing, it is not possible to operate the transformer in any high-voltage condition (usually in KV). A bushing is an electrical insulator that allows safe passage of electrical current. It is similar to any insulator surrounding the conductor, which helps prevent any untoward incident from occurring. A transformer consists of two windings - primary and secondary (HV and LV). It makes connections to external wires to carry electricity. Even though the transformer also include

What are high beam splitter coatings?  Basically, beam splitters are optical components that are used to split a certain amount of light into two separate beams. Splitters are classified according to how they are constructed. They can also be used to combine two different beams

What are highly reflective coatings? Originally high-reflective coatings were used to reduce light from lasers and other light sources while reflecting them. Therefore, technicians recommend that laser machines have highly reflective coating materials because the scatter of the laser beam can cause injury if the laser is pointed directly at the patient, for example, during laser eye surgery. In short, HR coatings are essential for laser machine effectiveness so that less laser power is used during application.

What are anti-reflection coatings? Basically an anti-reflection coating, also known as an antiglare coating, is used to reduce reflections on the surface of lenses and other optical components. When reflection is reduced it improves better imaging because reflection reduces light. Therefore, instruments such as binoculars, cameras, microscopes and binoculars can use anti-reflective coatings. This is because reducing light reflection by eliminating stray light improves image contrast. An antiglare coating can also be used to eliminate reflections. For example, in the lenses of glasses, technicians can use an anti-reflective coating to ensure that the person wearing the glasses can be seen by others. Additionally, an antiglare coating can reduce the glare from the light or binoculars of a secret viewer's telescope.
