How Do You Make A Current Transformer?
A current transformer is used to measure the current of a circuit into which an ammeter cannot be directly inserted. Transformers consist of two circuits linked with magnetizable material called a “core.” Both circuits have a length that coils around the core, to transmit energy from one circuit to another. In a current transformer, the primary (energy-transmitting) circuit loops through the core only once. The secondary circuit loops several times around the core. The core may be permanently in place around the primary or be hinged to fit around the line. Solid-core Transformer Step 1 Coil the copper wire around the iron ring, covering nearly all its surface. The windings can be overlapped or not. The greater the number of windings, the lower the secondary’s current can be made through the secondary, which will protect the delicate ammeter from overheating. Step 2 Cover the windings with electrical tape to hold them in place. Step 3 Strip the coating off the ends of the wire. Step 4 A
