The general standard IEC 60601-1 – Medical electrical equipment – Part 1: General requirements for basic safety and essential performance – gives general requirements of the series of standards. 60601 is a widely accepted benchmark for medical electrical equipment and compliance with IEC60601-1 has become a requirement for the commercialisation of electrical medical equipment in many ...
In electronics testing and servicing, an isolation transformer is a 1:1 (under load) power transformer used for safety. Without it, exposed live metal in a device under test is at a hazardous voltage relative to grounded objects such as a heating radiator or oscilloscope ground lead (a particular hazard with some old vacuum-tube equipment with ...
The international standard IEC 60601-1 Medical Electrical Equipment (3rd edition) specifies stringent criteria on the safety and isolation of medical devices. These requirements are of course much more stringent than those of a typical consumer product standard (i.e. IEC 60950 Safety of Information Technology Equipment), as the patient may be ...

Transformers are probably the most common means of galvanic isolation. They are almost universally used in power supplies because they are a mature technology that can carry significant power. They are also used to isolate data signals in Ethernet over twisted pair. [3] Transformers couple by magnetic flux.
An isolation transformer links two circuits magnetically, but provides no metallic conductive path between the circuits. An example application would be in the power supply for medical equipment, when it is necessary to prevent any leakage from the AC power system into devices connected to a patient.
Isolation amplifiers are used in medical instruments to ensure isolation of a patient from power supply leakage current. [1] Amplifiers with an isolation barrier allow the front-end of the amplifier to float with respect to common mode voltage to the limit of the barrier's breakdown voltage, which is often 1,000 volts or more.
MOPP safety standards aim to set basic safety requirements for medical electrical equipment. "With hazardous voltages present in a system a robust and reliable approach to isolation is needed such that multiple and un-related insulation system failures would need to occur before an operator or patient is put at risk.
