Hi all.
In some mast I found isolation transformer used by some FM radio.
Could it be useful to filter ac power in this mast ?
thanks
Normally yes but i would test with multimeter the secondary output there is no or very high resistive (Ohms) reading to the primary terminals this to establish if this transformer is isolation or just auto transformer, if unsure get local electrician to test for you and as always caution should be exercised with high AC voltages
