Q: Why should lighting transformers be used in factories and mines?: In some factories and mines (such as power plants), in order to supply power reliability, the power system is grounded in a three-phase, ungrounded, or neutral manner. In this way, the transformer must be connected to a neutral grounding type with a special transformer to supply power to the lighting.

Q: The difference between lighting transformers and control transformers: The lighting voltage is 36 and 12V, the signal lamp is 6V, the control winding is 127, 110V, the one or two insulation, and the two one is grounded.Simple lighting transformers, the two voltage is not so diverse.

Q: How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?: The number of tables in this table is increasing when the table rings to show 1.Method 2 is only to measure the capacitance is good or bad, can not be measured capacity.

Q: Is the substation separate from the power and illumination transformer?: The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.

Q: Can the 500 volt lighting transformer be changed into an electric welder?: The structure of the electric welding machine is different from that of the transformer, and the magnetic gap of the iron core can be adjusted so that the welding current can be changed. In addition, the output voltage of the welder is also soft

Q: Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?: 220V500W more power saving:Reasons: 1, high voltage, small current, line loss is small; 2, reduce the transformer and other intermediate links, each link has a loss.

Q: Power and lighting transformers, lighting quality will be affected much?: First look at this light. 24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sun. Its power comes from a generator or battery, and is lit by alternating current or direct current.

Q: Why can't autotransformer be used as transformer for safety lighting?: When a fault occurs, leakage of electric leakage occurs, and the original coil is transmitted to the residents at high voltage, causing disastrous effects on the human body and property!

Q: 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.

Q: 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.
