Collection:Safety Transformers

In isolating safety transformers, galvanic isolation is achieved between the AC power lines (mains) and the powered device. Thus, there is no DC path between the two windings. These transformers serve three main purposes:

• Isolation of the secondary winding from the ground (earth)
• Stepping line (mains) voltages up or down
• Reduction of line noise being transmitted from the primary to the secondary or vice versa

Isolation of devices connected to its secondary winding from the AC source on the primary, permits redirecting and controlling leakage currents. Moreover, they minimize the transmission of high frequency harmonics and noise. This makes them ideal for testing power-related devices.
