Q:The transformer zero line has broken, has the result to the household illumination circuit?

When the zero line break line is not broken, the voltage drift of the point voltage leads to the rise of the 220V branch voltage and the reduction of the 220V branch voltage

Q:3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?

Pure resistive load, the power factor is 1.3 *100W=300W, is required for the capacity of the transformer.

Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires

You must know the quantity and power of the lamp to determine the transformer

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: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?

The key is that the 220V terminals and 0 can not provide 1000VA capacity?

Q: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

Q:What transformer can be used in a safety voltage lighting transformer?

220V/36V or 24V isolation transformer. Double winding, high and low voltage coils, not connected.

Q:What's the function of the lighting transformer?

Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.

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: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)
