Automatic active phase selector

Automatic active phase selector

Whenever the supply of one or two phases of a three phase electrical line goes off, the APS system automatically distributes the electrical supply from the active phase to the failed phases. The switchover would be automatic and transient free. There will most likely have to be phase detection to get the switching action correct.

Products and services which our Company provides through the years got very good recognition and are widely acknowledged globally.

We introduce auto phase selector unit for those equipment whose supply is single phase. This allows us to design and manufacture new generation products with outstanding reliability and functionality. This ensures continuous power supply through all the three phases even if one phase is active. Technical Specification It monitors all three phases and pass one of them. The switchover would be automatic and transient free. I think you would have to analyze the effect of switching one phase to the other first anyway though, the effect on the load. The main difference between this and a three phase to single phase converter is that the input filter caps would have to be increased to be able to handle a single phase input, and the rectifier diodes on the input would have to be able to handle the full load current plus a little more as a single phase input would be designed. It would take in the three phase line voltages and output a single phase line voltage of the same level as either phase.

The single phase supply is selected automatically from three phases supply.

The objective of the APS is to ensure that there is continued commercial power supplied to the site at all times so as to ensure that the Base Transceiver Station BTS runs on commercial power until all available phases are either out of electrical tolerance or completely off. Some of the products by Novatek Electro have no analogues and could be considered at the level of scientific discoveries. Whenever the supply of one or two phases of a three phase electrical line goes off, the APS system automatically distributes the electrical supply from the active phase to the failed phases. Company consists of highly experienced specialists in the field of embedded technology as well as engineers of control and safe operation of all types of electric circuits and power systems. If the switching SCR's dont work because of too much phase overlap, you may have to use an alternate means such as a transistor with bridge rectifier. In addition, Novatek Electro has number of research workers, scientists with Ph. The objective of the APS is to ensure that there is continued commercial power supplied to the site at all times so as to ensure that the Base Transceiver Station BTS runs on commercial power until all available phases are either out of electrical tolerance or completely off. The switchover would be automatic and transient free. So the first thing to do is to analyze the effect of switching phases quickly, assuming it is done very fast. Thus, if a few transformers can be added that might help alot, although they would have to be able to handle the full load power. In auto mode the phase is automatically selected by the controller so there will be continuous uninterrupted supply to the unit. We welcome you at our site and invite you to effective, successful and mutually beneficial co-operation.

You also need power transformers too though. This allows us to design and manufacture new generation products with outstanding reliability and functionality.

That way if one phase or even two phases went down there would be absolutely no change on the output phase, and when the other phase s came back on line they would again help to supply the load power.

How to make automatic phase changer

For the switching, perhaps a micro controller or PROM and associated comparators to make the decisions. The single phase supply is selected automatically from three phases supply. That way if one phase or even two phases went down there would be absolutely no change on the output phase, and when the other phase s came back on line they would again help to supply the load power. Technical Specification It monitors all three phases and pass one of them. In auto mode the phase is automatically selected by the controller so there will be continuous uninterrupted supply to the unit. Last edited: Aug 20, One test is worth a thousand expert opinions, but one expert specification is worth a thousand tests. This is a micro controller based unit and is used with three phase electrical supply.

The problem is that if two phases go down at the same time this doesnt work. The load may have to take a brief interruption in power. If the effects are detrimental to the load, there will have to be a delay introduced to protect the load at least.

We introduce auto phase selector unit for those equipment whose supply is single phase. In auto mode the phase is automatically selected by the controller so there will be continuous uninterrupted supply to the unit. This ensures continuous power supply through all the three phases even if one phase is active. A Microcontroller based system will continuously monitor the incoming phase and accordingly display the details on an alphanumeric LCD also it will display the output phase. A Microcontroller based system will continuously monitor the incoming phase and accordingly display the details on an alphanumeric LCD also it will display the output phase. It would surely be a good idea to test this in a simulator first however to make sure the switching matrix method works ok. The single phase supply is selected automatically from three phases supply. Automatic Phase Selector Introduction: Industries require three phases power to run their machinery. Of course another idea that would be switching transient free would be to build an AC to AC converter. Technical Specification It monitors all three phases and pass one of them. The objective of the APS is to ensure that there is continued commercial power supplied to the site at all times so as to ensure that the Base Transceiver Station BTS runs on commercial power until all available phases are either out of electrical tolerance or completely off. For the switching, perhaps a micro controller or PROM and associated comparators to make the decisions. The assembly of products is being performed on the latest and modern equipments of known and reputed brands.
