Current transformer H11-3can behomemade. People can choose transformer's iron core which is not less than 2W to wind secondaryfirstly.It usesΦ 0.12 mm varnished wire to wind1,000 turns. The primary uses Φ 1 ~ 4mm plastic wireto wind2 - 3 turns. It also can use current transformer. Finished current transformer induced voltage is quite high.
