Q: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

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:Why should lighting transformers be used in factories and mines?

But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""

Q:How is the lighting power of the 380V transformer calculated?

The transformer (Transformer) principle should change the AC voltage of the primary coil, the main component of the device level by using electromagnetic coil core (core) main functions: voltage transformation, current transformer, impedance converter, isolation, voltage regulator

Q:Why is the two side of the lighting transformer grounded?

In the three-phase transformer, the neutral point of the three-phase transformer and the metal case are always reliably connected, and the utility model has the advantages of reliable grounding, both working grounding, protection and earthing, and protection of personal safety and equipment safety.

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: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:The difference between lighting transformers and control transformers

A control transformer is a low voltage appliance, usually used as a power supply or part of a lighting for the control of electrical equipment such as machine tools. There are usually two different voltage outputs,

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)

Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.

The self winding transformer is connected by all its windings, and depends on the position of the sliding contacts to change the magnitude of the voltage. Therefore, there is not only a magnetic connection between the primary winding of the autotransformer (the power circuit) and the two winding (the power supply circuit), but also the direct connection of the circuit. It forms a circuit with the earth, so it can not be used as the power source of the safety voltage
