Richard Gray’s Power Company Explains What an Isolation Transformer Does

Residential Systems interviewed Alex Gianaras, president and CEO of Richard Gray’s Power Company for the March issue. In this exclusive online extra, Gianaras explains what an isolation transformer is and what it does:

Isolation transformers are a critical component of every Richard Gray’s Power Company Isolation Purification products; it’s our “core” technology if you will. Wikipedia provides a great explanation: “An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits, which must not be connected. Isolation transformers block transmission of the DC component in signals from one circuit to the other, but allow AC components in signals to pass. Suitably designed isolation transformers block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers or laboratory instruments.”

Isolation Transformers are an essential building block of the RGPC line. In fact, we utilize AV grade magnetic isolation transformers in all RGPC AC Power Purification Isolation products, including the Substation, Substation RM Pro, and PowerHouse because their heavy duty Faraday Shield stops AC power interference that can destroy and degrade the performance of AC-powered equipment. Coupled with the RGPC exclusive filtering system, this design creates a true, dedicated AC power delivery system capable of reducing a 6,000 Volt AC surge event to less than 12V at its output, resulting in a true power conditioning system.

Additionally, our isolation transformers help to deliver more power where the power is needed by transforming 240VAC to 120VAC, thus eliminating the need for multiple AC power outlets or the creation of long ground and neutral wires, either or both of which result in ground loops that produce electrical noise and other AC power faults.
