Here displayed 4 simplified different ways to identify whether you have single or 3-phase power to your home. Way 1 Make a phone call. Without getting over technical and to save you the effort of looking at your electrical switchboard, there is someone who will know instantly. Your electricity supply company. The good news, they’re only a phone ca...Read more -
What’s the Difference between Single-phase and Three-phase Power?
In electricity, the phase refers to the distribution of a load. What is the difference between single-phase and three-phase power supplies? The difference between three phase and single phase is primarily in the voltage that is received through each type of wire. There is no such thing as two-phase power, which is a surprise to some people. Single-phase power is commonly called ‘split-phase’. Residential homes are usually served by a single-phase power supply, while commercial an...Read more -
NASA selects SpaceX Falcon Heavy to promote new Gateway lunar space station
SpaceX is known for its excellent launch and landing, and now it has won another high-profile launch contract from NASA. The agency chose Elon Musk’s Rocket Company to send the initial parts of its long-awaited lunar passage into space. The Gateway is considered to be the first long-term outpost for mankind on the moon, which is a small space station. But unlike the International Space Station, which orbits the Earth relatively low, the gateway will orbit the Moon. It will support the u...Read more -

Difference between WIFI, BLUETOOTH and ZIGBEE WIRELESS
Home automation is all the rage these days. There are many different wireless protocols out there, but the ones that most people have heard of are WiFi and Bluetooth because these are used in devices that lots of us have, mobile phones and computers. But there is a third alternative called ZigBee that is designed for control and instrumentation. The one thing that all three have in common is that they operate at about the same frequency — on or about 2.4 GHz. The similarities end there. So ...Read more -
Advantages of LEDs When Compared To Traditional Lightings
Here are the advantages of light emitting diode lighting technology. Hope this can help you know more about LED lightings. 1. LED Light Lifespan: Easily the most significant advantage of LEDs when compared to traditional lighting solutions is the long lifespan. The average LED lasts 50,000 operating hours to 100,000 operating hours or more. That is 2-4 times as long as most fluorescent, metal halide, and even sodium vapor lights. It is more than 40 times as long as the average incandescent bu...Read more -
