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 ...
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 ...
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 ...

A transformer is the most widespread example of galvanic isolation. An opto-isolator is a very popular method of isolation in digital circuits. Cross-section of dual in-line package opto-isolators. Relative sizes of LED (red) and sensor (green) are exaggerated.
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.
An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth.It is intended to give an alert (light and sound) or disconnect the power supply when the resistance between the two conductors drops below a set value, usually 50 kΩ (sample of IEC standard for medical applications).
