Why Does DC Have More Waste (Less Efficiency) Over Long Distance Than AC? DC produces more waste than AC over long distances because DC voltage cannot be increased or decreased using transformers like AC voltage. This means that DC lines must use thicker wires to transmit the same amount of energy as AC lines. Thicker
Why Can’t The Steam Released By A Thermal Power Plant Be Condensed Into Water And Used Again In The Plant? The steam released from the thermoelectric power plant can be condensed into water and reused in the factory. This is called a closed-loop system. However, additional hardware and power are required to operate. Most thermal
How Much Power Does A Normal Elevator Consume? Elevatorenergy consumption can vary depending on factors such as size, speed, age, and use of the elevator. However, a typical elevator uses an average of 2 to 7 kilowatts (kW) of energy per hour. Depending on usage, this can result in annual energy consumption of between 17,000 and 70,000 kilowatt hours (kWh) per elevator. It should be noted that newer
What Are The Small Red Lights Around The CCTV Cameras? The small red lights around CCTV cameras are called infrared diodes or infrared diodes. They are specifically designed for lighting in lowlight conditions or complete darkness, enabling clear images and video recordingatnight³⁵. Serves as a visual signal to inform people that their activities are being monitored and recorded and serves as a deterrent to potential criminals or intruders². A red light on a security camera usually indicates that the camera is recording or is in
Why Do We Measure Electricity In KWH And Not In Ampere-Hours? Electricity is measured in kilowatt-hours (kWh) because it can be easily converted across the entire spectrum of electricity consumption. Akilowatthour is equivalent to one kilowatt of energy consumed in one hour. batteries, on the other hand, are measured in amphours (Ah) as this is an indicator of the battery’s energy storage capacity. amp hours refers to the minimum number of amps that can be drawn from a fully charged battery for one hour before it can no
What Is Buchholz Relay? Which Equipment Is Protected By It? A Buchholz relay is a protective device installed on some oil transformers and power reactors equipped with an external overhead oil tank called a “conservator”. Used to detect the effects of dielectric faults in the device, such as B.Gas buildup, oil leaks, or overheating. ¹²The Buchholz relay has two floats with mercury switches in a metal chamber connected to the pipeline between the expansion tank and the main tank. When
What Is An Isolation Transformer? An isolation transformer is a type of transformer that transfers electrical energy from one circuit to another without a direct connection between them. It is used for safety reasons, to reduce noise and interference, and to isolate various parts of the system. ¹An isolation transformer has two windings: a primary winding and a secondary winding. The primary winding is connected
What Is Stepper Motor. What Are Its Uses? A stepper motor is a type of electric motor that can rotate in discrete steps, or angles, by receiving a series of electric pulses. The advantage of a stepper motor is that it can move and hold its position precisely without any feedback sensor, as long as
Why Doesn’t Neutral Wire Give A Shock? The neutral wire is the wire that carries current back to the source after passing through a load (such as a light bulb or appliance). The neutral wire is usually connected to the ground on the motherboard, meaning it has the same potential as the ground. Therefore, under normal conditions, the neutral wire does not cause electric shock because there
What’s The Minimum Distance Between An MV Cable (13.8kV) And A Fiber Optic Cable? The minimum distance between the the medium voltage (13.8kV) cable and the fiber optic cable varies depending on the specific regulations and standards of your region. However, as a general guideline, the U.S. National Electrical Code (NEC) requires a minimum distance of 3 feet (0.9 meters) between medium voltage cables and other electrical equipment.
