Hello everyone, welcome to Testka Technologies Private Limited, myself Erwin Paliwal and I am here to explain the working of single-page transform. This, the T2B are using has ordered pulled 690.6. A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors called transformer coils. A varying current in the first or primary windings create a varying magnetic flux in the transformer's core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electro-mote force or voltage in the secondary winding. Basic principle of transformer. Transformer is based on two principles. First, that an electric current can produce a magnetic field and second that a changing magnetic field within a coil of wire induces a voltage across the ends of the coils. The transformer we are using is 1KVA 230 volt, primary and 230 volt, secondary, cold type, air, cool copper, out transformer. And another category is in this too. Like 1KVA 2KVA and 5KVA. So now we will connect the input of value on the neutral and 230 volt supply of the input or primary winding of single-page transformer. And now we will measure the output of the single-page transformer on all neutral to 158K volt, neutral to 1 and 15 volt and neutral to 200 volt and neutral to 230 volts. So now you can see a digital multimeter that on neutral and 58 volt output of secondary winding we have 57 volts current. On 115 we have 115 volts current. On output side of 200 we get 200 volt. You can see digital multimeter and in 230 we get 230 volts. So now you can see that on giving on a higher input we are getting a step down on different voltage values like 58, 115 and 200 volts. Similarly, if you supply neutral to 1 and 15 volt you can get any amount of voltage you require from the output side like neutral to 230 volt neutral to 200 volt. So it has step down step up transformer it works on both sides. So with this we end our experiment on single-page transformer. If you like it please like, subscribe and share.
