Furnace Ignition Transformer types
The main partition is by current; either DC or AC. As the names indicate, an AC transformer works on alternating current whereas the DC electric arc furnace transformer works in DC current. A 24v furnace transformer operates under 24 volts of electric voltage difference. A furnace 24 volt transformer might sometimes be mistaken for a doorbell transformer. But they are very different things and there is no such thing as a furnace doorbell transformer.
Induction furnace transformer uses the available 3 phase AC electricity to provide the necessary DC electricity to the induction system. The induction system produces eddy currents in the charge and heats the contents of the furnace. A gas furnace transformer is used in a gas furnace. Furnace oil transformer is used to heating up the oil in an oil furnace before ignition. Transformer for electric furnace can be applied for 120v to 24v transformer furnace. A furnace thermostat transformer works with a thermostat in a transformer to automatically switch on or off the furnace. A 24 volt furnace transformer is very energy efficient as it requires such low loads of voltage.
Electric arc furnace transformer
There is a solid difference between an induction furnace and an electric arc furnace. The induction furnace uses an induction system where the materials to heat up are put inside a container where they are heated by eddy currents resulting from the induction system. For this, DC currents are used, and the specified transformers are used. The electric arc furnace on the other hand uses charged materials to be heated. The electricity flows right through the materials in the form of an electric arc which requires very high voltage and load of currents. The electric arc passes through the material and heats it up much faster than the induction system.
Electric Furnace Transformer Price have their differences due to the labor cost incurred in the manufacturing countries. As for the electric arc furnace transformer manufacturers in India, the labor costs are cut down by about 30% and the prices are low compared to foreign productions. And Rajasthan Powergen Transformer P. Ltd. is one of the well-known electric arc furnace transformer manufacturers in India.

There are two types of arc furnaces namely:
- Direct Electric Arc Furnace
- Indirect Electric Arc Furnace
The working of electric furnace incorporates charging the electrode, emergency period (melting the metal) and refining. The overwhelming and light scrap within the large basket is preheated with the assistance of exhaust gas. For speeding up the slag arrangement, burnt lime and fight are included to it. The charging of furnace takes put by swinging the roof of the heater. As per prerequisite, the hot metal charging moreover takes place.
Following is the emergency period. The electrodes are moved down onto the scrap in this period. At that point the bend is delivered between the electrode and metal. By considering the protection viewpoint, low voltage is chosen for this. After the bend is protected by electrodes, the voltage is expanded for speeding up the melting process. In this process, carbon, silicon, and manganese get oxidized. The lower current is required for expansive arc generation. The heat loss is additionally less in this. Melting down prepare can be securing by deep washing of electrodes.
Refining process begins during melting. The removal of sulfur isn’t fundamental for single oxidizing slag practice. As it were phosphorous removal is required in this. But in double slag practice, both (S and P) are to be evacuated. After the deoxidizing; in double slag practice, the evacuation of oxidizing slag is performed. Next, with the assistance of aluminum or ferromanganese or ferrosilicon, it gets deoxidized. When the showering chemistry and required temperature is come to, the warm will get deoxidized. At that point, the liquid metal is prepared for tapping.
The most parts of electric furnace are the roof, terminals, hearth (lower portion of a heater, from where liquid metal is collected) and side walls. The roof comprises of three holes through which the electrodes are embedded. The roof is made up of alumina and magnesite-chromite bricks. The hearth incorporates metal and slag. The tilting component is utilized to pour the metal that’s liquid to the support by moving the furnace.
For the electrode expulsion and furnace charging (topping up scrap metals), roof withdrawal component is incorporated. The arrangement for smolder extraction is additionally given around the heater considering the wellbeing of administrators. In AC electric furnace, anodes are three in number. These are round in segment. Graphite is utilized as electrodes since of high electric conductivity. Carbon electrodes are too utilized. The terminals situating framework helps to raise and lower the anodes consequently. The electrodes get profoundly oxidized when the current thickness is high.

Transformer failures are unusual to hear about. In case of too high a voltage or current passing through the coil, the circuit breaks down by the heating of the winding.
The breakdown of the primary and secondary winding can also be checked and it is easier in case of a linear transformer. It can be done by applying ac voltage to the primary winding. If there is very low or absence of voltage from the secondary side then it signifies the opening of the winding of the transformer. Signs of overheating like the peculiar smell can be easily noticed. Testing a power transformer is a little tough as load has to be connected without which there are chances of overload. Linear transformer are the ones which can be tested in the absence of load and the switch mode power supply work with load while linear transformer can be test without load.
So to test a switch mode power transformer firstly one has to disconnect it from the board and then Check the primary winding because it is very for secondary winding to fail. One can distinguish primary winding from the secondary by Using a filter cap. The positive pin of the bag will go to the pin of the transformer and the middle pin that is the drain will lead to a pin of the transformer . These two pins make primary winding. This method through resistance checks if the coil ha opened or not. So to check if it has shortened or not one has to apply ringer test.
The most cost effective ringer tester is Dick Smith LOPT METER or flyback tester. It can instantly tell the results on the bar graph by connecting its probes to the primary winding. A reading of 4-8 means full winding, 1-2 bar signifies partial shortening and switching off of the represents heavy shortening in the coil.
The equipment is an expensive ringer which can check all kinds of windings of all the transformers. Transformer repair requires skill and knowledge and is definitely not easy to perform. The people who repair the transformers like to rewind the bigger windings like the fan, car alternator etc . This make the Switch mode power transformer a bit tough to rewind owning to its small size and cheap pricing.

When an HVAC (Heating, Ventilation, Air Conditioning) framework doesn’t work quite because it should, exceptionally frequently it can be followed to a issue with the thermostat. Since these are simpler to fix, the thermostat is the primary place to seek for issues. In the event that the inconvenience isn’t there, at that point the issue may be within the furnace itself.
There are three HVAC side effects that can frequently be followed to issues with the thermostat:
- The furnace does not set the temperature to the desired level—it is either too cold or too warm
- The system produces no heat or cooled air
- The system cycles (turns on and off) too frequently
Possible Causes
- Loose wires or open connection in the thermostat
- Thermostat components are dirty
- A bad battery on digital electronic thermostats
- Circuit breaker tripped or fuse is blown
Possible electric furnace transformer troubleshooting:
- Reset circuit breaker or replace burned out fuse
- Remove thermostat cover and gently clean components, especially the bimetallic coil and the switch contact surfaces.
- Set the thermostat to its lowest setting and clean the bimetallic coil with a soft brush or compressed air.
- Set the thermostat to its highest setting and clean the coil again.
- Then, reset the thermostat to its desired setting.
- Tighten any loose screw terminals.
- If a wire is loose from its terminal, place the wire back on the terminal clamp and tighten the screw.
- Check for loose connections or disconnected wires on a low-voltage transformer, which is usually mounted on the furnace.
- On electronic thermostat models, check to see if the display is working, indicating power. If it is not working, replace the batteries in the thermostat.
- Loose wire
- Clogged filter
- Contact with water
- Wrong fuse
- Dirty fuse
- Faulty starting capacitor
- Transformer failure
- Bad blower motor
- Failing valve
- Electric furnace thermostat control wire
