FAQ

How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)
Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
So, safety regulations: lighting transformer must double winding type safety isolating transformer, prohibited the use of autotransformer.
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.
Can the 500 volt lighting transformer be changed into an electric welder?
The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.
What transformer can be used in a safety voltage lighting transformer?
An isolated transformer is a transformer that is electrically isolated from an input winding and an output winding. The isolated transformer is used to avoid accidental touching of the charged body at the same time, and the isolation of the transformer is to isolate the current of the former side winding coil.
Why is elevator lighting transformer installed?
1) a lamp shall be installed at the highest and lowest point 0.5m away from the hoistway, and a light shall be installed at intervals not exceeding 7m, and a control switch shall be installed in the engine room and the bottom pit respectively;2) the lighting power supply for car top and hoistway shall be 36V; when 220V is adopted, the residual current action protector shall be installed;3) there is no lighting device for a closed well road with sufficient lighting conditions around the hoistway.
How to calculate the rated capacity of small transformers for lighting purposes?
Capacity of power transformer is the basic equipment for a total capacity of [kW] (maximum power consumption rate by a / X100 capacity) divided by the power load [%] value for benchmarking.
How is the lighting power of the 380V transformer calculated?
With a light bulb with 4KVA load, the premise of the distance can be Mrs. face light bulb, dark can light the best load, 3KVA bulb brightness
