FAQ

Why can't autotransformer be used as transformer for safety lighting?
The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together
Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?
See whether the lamp power saving, can not see whether it has a transformer, but to see the light efficiency of the lamp, that is, the ratio of light flux to power!Popular speaking, that is, spend the same electricity to see who sends more light!So, when comparing, ask what the light is, then judge again!The luminous efficiency unit is LM/W
Is the substation separate from the power and illumination transformer?
The power and lighting power supply in the substation need not be separated. In a large capacity power plant, the lighting can be electrically powered to ensure that the generator is stopped. The lighting source is often separated from the lighting transformer and powered by other power supplies.
Who knows how big transformers and lines the 36V transformer uses in lighting?
How many transformers should be used in the lighting of the 36V transformer, which should be chosen according to the power required. The greater the load (power), the greater the power to select the transformer.
How to calculate the rated capacity of small transformers for lighting purposes?
In view of the power [kVA] conversion of each load, multiplied by the amount of consumption, according to the importance of the load, equipment location, voltage statistics, set the load line and load place of plastic case transformer capacity and its connection position. The future load power equipment shall be judged on the basis of prior installation or consideration of the economy in terms of equipment addition, installation, etc..
Does the lighting work properly? Doesn't that power equipment start voltage unstable?
As long as the capacity of the transformer is enough, the voltage fluctuation of the line will be sure to occur when the high power equipment is started. Such fluctuations do not have much impact on the lighting.
How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?
Voltage x current = power, in general we are using the total power of 2/3, you can press this type of calculation, if the installation of electrodeless lights, the line should be separated,
Lighting, lights, transformers, bulb brightness is too low, what's the matter?
If you share a power line, you must calculate the current and select the appropriate wire to ensure normal pressure drop and safe use.
