There main reason why it is compulsory to install a circuit breaker in your home is that it protects against overload and short circuits. As we know, electricity is necessary for household operation. Lights, fans, refrigerators, TV and all the other appliances need electricity to work. However, the electric supply is not stable. Due to storms and faults, the power can cause overload, which can be fatal. It will not only damage your appliances but also result in casualties. In order to avoid these unforeseen circumstances, you need to install circuit breakers. It is a protective system that helps to protect your homes against power surge and many other problems.  If you want to know more about circuit breakers, follow this guide. In this article, we are going to explain how circuit breakers protect our homes.  How Does A Circuit Breaker Work? A circuit breaker is a device that protects electrical wires in a home from being overloaded. An overloaded electrical circuit could result in the failure of electrical appliances and electronic devices.  If an overload occurs, the breaker can cut power to the entire house or a specified zone. The process does not depend on the number of appliances present but rather on the size of the wires and the amount of electrical load. The circuit breaker interrupts the flow of electrical current when it senses an overcurrent. It does this by tripping the breaker, which cuts off the flow of electricity. If a fire or electrical shock occurs, the breaker shuts off the […]

What is a Low Voltage Circuit Breaker? Usually, when a high load of voltage is being drawn, no machine can control that. In the case of short circuits or loops or lightning, millions of volts strike the power supply. In that case, eventually, a high voltage touches the system as there is no resistance. To provide that resistance, circuit breakers are being used. How does it work? It is very simple. When a high voltage passes through an electric connection, up to a certain range it is allowed by a circuit breaker. But at once a certain range is covered, it will cut the connection with the main supply. So, it doesn’t matter what the range of the electricity is, it will be saved. Now there are two categories of circuit breakers. One is a high voltage circuit breaker and another is a low voltage circuit breaker. Let’s see what’s the difference. High Voltage Circuit Breaker Vs Low Voltage Circuit Breaker The basic difference between high voltage and low voltage circuit breakers in the range of the voltage. When the voltage limit is fixed up to 1000 volt, then it’s a low voltage circuit breaker. When the voltage ratio can be extended more than 1000 volt, then it’s a high voltage circuit breaker. Because of several great benefits, it is being highly used in residential areas. Let’s see what are the beneficial reasons. What Are The Advantages of Using Low Voltage Circuit Breakers? As already mentioned in the definition a low voltage circuit breaker has a […]

Il principio di funzionamento del MPPT fotovoltaico

08 febbraio 2022

The working principle of a photovoltaic MPPT is simple enough. It works by averaging the PV power value so that the response is lower when the system is below its optimal powerpoint.  Similarly, a maximum power point tracking system will require a high-speed tracking device to keep up with changes in the irradiance. The maximum power point is a function of the PV module’s total irradiance and output voltage. The working principle of an MPPT controller is to track the optimal current for maximum transfer of power. A PV panel’s internal resistance is high, and when it is short-circuited, it delivers zero energy.  Since a PV panel has high resistance, it is a natural phenomenon that it loses energy when there is no load, making it essential to have a proper MPPT controller. An MPPT controller will track the correct current for maximum power transfer, based on a number of factors, including the amount of insolation, load voltage, and the PV panel’s resistance. If you want to know more about the working principle of photovoltaic MPPT, continue reading this article.  What is a Photovoltaic MPPT? If you’re wondering what an MPPT is, you’re not alone. Almost all solar energy systems have one, and the technology behind it is getting better all the time. The MPPT helps keep your array operating at peak performance. The technology works by constantly monitoring the voltage and current of the array to drive the inverter to its maximum output power. In many cases, a dual MPPT is more effective than […]

Often on rainy days, lighting causes harm to us. Whether it is direct striking on the antenna or the mainboard. In both cases, serious hampering of the electrical machines may happen. Having such a high loss is not expected. The step that was taken some years ago was to close the main circuit board and cut the supply. So it wouldn’t hamper any electrical machines as the connection was detached. But in your absence who will protect your home? That’s why they need for an automated device was required. A circuit breaker is the perfect example of it. Let’s see what it is and how it works. Definition Of Circuit Breaker The mechanism of the circuit breaker is designed in a manner that for a sudden electrical load or for a faulty current, it will break the connection with the main circuit board. It simply prevents the electric machines from high voltages. It controls the opening and closing of the connection to the mainboard. How Many Types Of Circuit Breakers Are There? Circuit breakers are of two categories mainly. Those are high-rated circuit breakers and low-rated circuit breakers. High-rated circuit breakers are those which can tolerate more than 1000 voltages. Like lighting. Lightings carry millions of voltages. Low-rated circuit breakers are of less than 1000 voltages. These are generally enough to bear short circuit issues. However, a high-rated circuit breaker can control everything properly. Apart from these names, there are some types of circuit breakers available. A detailed discussion on those parts is given below.

Whether you need to turn on and off various appliances, such as water fountains or pool pumps, a timer switch can help you save on your energy bills. There are many uses for time switches, including reducing the likelihood of burglary. Mechanical timers use dials and time switches to set the timing. In contrast, digital timers use electronic timers that require no manual input. GEYA offers several models of digital timer switches, each with similar functions. Both the digital and the mechanical timer switches are available in both switch and plug-in modules. The differences are minor compared to their functions.  The mechanical timer is more bulky and able to handle more electric load. The latter is more aesthetic and small. The mechanical timer is also limited to 24 hours of operation, while the digital one is flexible enough to control up to seven days a week. If you want to know more about mechanical vs. digital timer switches in the application, continue reading this article.  What Are Mechanical Time Switches?
