Q:How many power illuminator can 5Kva 36V transformer drive?: The load capacity of the transformer is 70% of its nominal power, so it is concluded that the transformer you provide can drive the 3.5KVA 36V lighting appliance (which is used in normal condition and environment)

Q: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

Q: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.

Q:What type of low voltage transformer should be adopted for safety lighting power supply?: In general, indoor transformers are used in general practice

Q:How to calculate the rated capacity of small transformers for lighting purposes?: But in fact, consider the total load, the importance, the location of the machine, and the future additional plan, according to the following order.

Q:Does the lighting work properly? Doesn't that power equipment start voltage unstable?: The transformer that power supply company manages, it is to supply motive power and illumination generally, namely the lighting transformer that does not have special illumination to illuminate. Units of their own transformers, is generally the case. The utility model has the advantages that the transformer and other equipment can be fully utilized, the efficiency is high, and the external power supply circuit does not need to be divided into power transmission lines and lighting circuits, and is simple and orderly, and the cost is low. As for the price of electricity, it is usually negotiated a power and lighting each percentage of the electricity to calculate and receive.

Q:What transformer can be used in a safety voltage lighting transformer?: Early European countries used in the power industry, widely used in the electronic industry or industrial and mining enterprises, machine tools and machinery equipment general circuit control power supply, safety lighting and indicator light power supply.

Q:What's the function of the lighting transformer?: In addition, can be rated power supply voltage of not more than 1000V AC circuit, as a machine tool and mechanical equipment control power, work lighting and signal light power supply, can also be used as a small power supply!

Q:The difference between lighting transformers and control transformers: Lighting transformer voltage is generally rated by a group or two setsControl transformers have many levels of output voltage

Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?: If there is no painting can be used with a diode symbol file (measuring probe connected to the capacitor to hear a sound if the table does not ring at the table and then the general display is 1, then the pen on the emergence of the phenomenon that the capacitance is still good. If one table has been ringing that received the capacitor capacitor breakdown is broken)
