What is cooling system in transformer?
oil is used in high voltage transformers. It must be serviced and changed by usually major electric service providers Transformer oil has heat conductive properties, along with its insulating properties, that take the heat build up from the windings to the outer case of the transformer. The transformer tank is used as a heat sink to allow the outside ambient temperature to cool it down. On big KVA transformers there are heat tubes on the outside of the tank. On even bigger transformers there are fins that the oil travels through. This provides a bigger surface area to dissipate the heat. The tubes and fins also allow thermal siphon of the oil through the tubes by drawing in the cooler oil at the bottom of the tank and moving it to the top of the tank where the hotter oil is. This circulation greatly increases the cooling ability of the oil to keep the transformer with in its allowable temperature rate of rise zone.
Does an ammeter measure current?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
An electric current is the measure of what?
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
What is difference between ac and dc voltages?
AC stands for alternating current, which is an electrical current that frequently reverses direction. AC electricity is measured according to its cycles, with one complete cycle being counted each time a given current travels in one direction and then doubles back on itself. An electrical current is able to complete many cycles per second, and is then given its frequency rating based on that number; for example, the typical frequency in North America is 60 hertz (Hz), which indicates that the current is performing 60 cycles per second. AC power is the type of electricity most commonly used in homes and offices, and is extremely versatile because its voltage can be changed through a transformer to suit a variety of transmission needs.What Is DC Power?DC is the abbreviation for direct current, which is a type of electrical current that travels through a circuit in only one direction. Direct current is the type of electrical power that is produced by fuel cells, batteries, and generators equipped with commutators. While DC power was the first type of electricity to be commercially transmitted, it has been widely replaced by alternating current (AC) electricity, and is now used primarily in electrochemical and metal-plating applications.
Electrically how is AC different from DC current?
DC is direct current, current travels in one direction. AC is alternating current, current changes direction twice per cycle. 60 Hertz would change direction 120 times per second.
What happens when current travels through the second transformer before entering your home?
When current travels through the second transformer before entering your home, it undergoes a further step of voltage reduction and may be adjusted for the specific requirements of the local distribution network. This helps ensure a safe and consistent supply of electricity to your home at the appropriate voltage levels for your appliances and devices.
How do resistors affect a circuit?
It reduces the current. As the current travels through the resitors it has some current that is left in the resistor. And
What will happen if you connect a battery to a small light bulb with a single wire?
Nothing will happen. It requires two wires to complete the circuit. Electrical current travels from the battery terminal through the wire to a metal portion of the base of the lightbulb. The current then travels up through the filament wire which glows as the current travels through. The current then travels back down the other side of the filament wire to the base of the bulb and thus through the second wire back to source, which is the battery.
What electrical current flows through electrical home devices?
The electrical current for a home device travels in a circuit.
What pathway through which electricity travels is called?
The pathway through which electricity travels is called a circuit. A circuit consists of a closed loop for the flow of electric current.
When a light switch is turned on what travels through the wire?
Current flows through a wire when a light switch is turned on.
What will happen if one battery terminal is connected to a light bulb?
Nothing will happen. It requires two wires to complete the circuit. Electrical current travels from the battery terminal through the wire to a metal portion of the base of the lightbulb. The current then travels up through the filament wire which glows as the current travels through. The current then travels back down the other side of the filament wire to the base of the bulb and thus through the second wire back to source, which is the battery.
What increases the speed of sound?
The speed of sound generally increases with temperature and the elasticity of the medium through which it travels. In gases, sound travels faster at higher temperatures, while in solids and liquids, the speed of sound is influenced by factors like density and stiffness.
What is the relationship between the speed of a longitudinal wave and the medium through which it travels?
The speed of a longitudinal wave is determined by the properties of the medium through which it travels. Different mediums have different densities and elasticities, which affect how fast the wave can travel through them. In general, the speed of a longitudinal wave increases with the stiffness and density of the medium.
When lightning hits a lightning rod does it create spark or fire?
No, the current simply travels through the rod and spreads into the earth.
What and a conductor through which electric current travels through?
A conductor is a material through which electric current can easily flow. Metals like copper and aluminum are commonly used as conductors due to their high conductivity. When a voltage is applied across a conductor, electric charges move through the material, creating an electric current.
When a mechanic increases the force acting on an object what happens to the distance the object moves?
When the Force increases on an Object, the Distance it travels INCREASES, as does its Velocity.
