calculate the total sum of lighting power and add 10% as safe operation of the transformer. then select a transformer for that rating.
suppose your total lighting power is 300VA. add 10% of the total lighting power so the total power is 330VA. therefore your transformer size can be 330va or more.
please follow IEE regulations.
Stepdown Transformer.
Well it depends on what type of transformer you are talking about, but usually, no it is not normal.
Due to the heavy coils found inside the body also you will find an insulation that is oil type, that s why it s so heavy , but if u look at the dry type transformer u will find it so light and compact that s all i know my sir Eng: Amr <<>> The reason that power transformers are so heavy is from the steel laminations that the core of the transformer is built from. The outside transformer is constructed out of steel which also adds to the weight. Transformer coils these days are using aluminium wire for the primary and secondary wraps. This keeps the weight down and also helps in preventing copper theft.
Restricted earth fault protection is used to protect a specific zone, and should not trip for a fault outside of that zone (usually limited to a transformer, and possibly extending to lowside, highside, and tertiary breakers). Stand by earth fault protection is a term I am not very familiar with, but I believe this would be protection that is meant for a specific zone as backup, and can operate for faults outside of this zone. An example might be a highside time overcurrent relay set looking into a transformer, where the transformer is protected by a differential (primary protection), and there is a lowside feeder with relays (primary protection). The highside overcurrent acts as a backup (secondary protection) for the transformer and the feeder, and is delayed due to the nature of a time overcurrent relay.
Actually an isolation transformer may be physically the same as a Step up/Step Down transformer. The main difference is in the way they are used. Another difference is that in a normal transformer there will be capacitance between the 2 windings, between the windings and core, between the core and shell, etc. These capacitances bring in high frequency noise from outside, which will be transmitted in the secondary circuit. So [in an isolation transformer] wires are connected between each component, (not direct contact, but with insulation present). This permits a leakage current and eliminates unnecessary capacitance. I could make a start to answer this question. Isolation transformer: is a transformer with two separate windings, the primary and the secondary. There is an electrical isolation between the primary and the secondary. Nearly any type of transformer with two non-connected windings could be considered an "isolation" transformer, in that it electrically isolates the primary voltage from the secondary voltage. There are also transformers with one winding (called auto-transformers) and connections for input and output. If the input is low voltage and the output a higher, then you can say it is a STEP-UP transformer. If the input is high and the output is low, then you can say it is a STEP-DOWN. This type of transformer can not by used where safety is a large factor.
Stepdown Transformer.
Yes, although it is not as common you can use pendant lighting outside your home. A company called ELK has recently released a line of pendant outdoor lighting.
In North America the transformer outside your home is classed as a step down transformer. It steps down a higher voltage (14000) to the split house working voltage of (120/240).
Outside lighting is a great thing to have for a home because it utilizes the outdoor space at night. People can see where they are going with lights on, and you can entertain guests at night with outdoor lighting.
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
Yes, pathway lighting works great. It can efficiently light up your outside and can last for a very long time.
Well it depends on what type of transformer you are talking about, but usually, no it is not normal.
I am looking to light up my walkway. Where can I view options in outside lighting online?
There are several kinds of track lighting available, many specifically designed for outdoor use. When following installation correctly, outdoor track lighting will be safe outside during the rain and wind.
If they each have a transformer then you do not need another one. <<>> Be very careful about answers you receive. In most occasions the primary of the low voltage is usually 120 or 240 volts. This high voltage must be treated like any other normal home wiring using the correct size breaker for the load. If that transformer is in an outside damp or wet location a GFCI must be used for personal safety protection. The supply can be an outside GFCI receptacle or a dedicated circuit directly from the supply distribution fed with a GFCI breaker installed in the panel.
I'm trying to get my home owners insurance lowered. How much outside lighting will I have to get to have my rates lowered?
