What is the function of radiator in power and distribution transformer?
Radiators are used in a transformer to cool the transformer oil through natural air or forced air flowing in these radiator fins. As the transformer oil temperature goes down due to cooling it goes to the transformer tank from bottom ,cool the windings and gets heated, and then returns to the radiator for next cooling .This cycle repeats as the oil flow is also natural due difference in temperature of oil on bottom and top. In big power transformers this oil circulation is forced by oil pumps for effective cooling. The radiator has many small fins and there are 4-10 radiator banks in a transformer depending on capacity and make of the transformer.
Why the arrow direction marked on top of the bucholz relay on power transformer?
The indicates the direction for correct installation. Bucholz relay operates when gas bubbles in the transformer oil pass through the relay in its pathway. The relay has to be installed arrow indicating upwards.
How high from the floor do you install an entry light?
Standard rule, top to the fixture same height as top to the door.
What are electrical wiring codes in the Philippines?
As with any electrical codes throughout the world it is a document for the safe installation and handling of electrical wiring. The set of instruction on how to install equipment is different in many parts of the world due to the different voltages and climatic conditions in which the wiring is installed. The top concern of any code rule is for the safety of the people who use electricity.
Is oil in transformer use for lubrication?
Transformer oil is for cooling.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.Additional AnswerThe second function of transformer oil is insulation. Oil has a far greater dielectric strength than air, so it enables internal components at different potentials to be located far closer together -thus significantly reducing the 'footprint' of a transformer.

go outside and look
On exit signs is light bulb red or it just the plasitc overe top of it?
the lightbulb is not red if its that important to you
How tall does a building have to be to have a red plane light on the top?

Can you top up a transformer on load?
You will have to restate your question. What do you mean by 'top up'?
What does a red warning light on vw lt 35 instrument panel mean?
If its the small red light at top of clock and its flashing... your water / coolant level is low.
Why transformers were made?
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. You'll see transformers at the top of utility poles and even changing the voltage in a toy train set.A transformer changes electricity from high to low voltage using two properties of electricity.
