Introduction - TASKING iSYSTEM CoreSight Hardware User Manual

Introduction

Galvanic isolation is used where two electric circuits must communicate, but their grounds may
be at different potentials. It is an effective method of breaking ground loops between the two cir-
cuits. Galvanic isolation is also used for safety, preventing accidental current from reaching
ground through a person's body.
Galvanic Isolation Adapters provide a basic isolation that withstands high voltages.
To prevent injury to personnel when dealing with potentially hazardous voltages it is mandatory
to have a second protection measure in place, in case the first insulation barrier fails. This is
termed double or, reinforced isolation. How should a double isolation be implemented depends
on the use-case or application setup.
It is your responsibility to check the local safety directives applicable to your com-
pany and country to ensure that all requirements are met.
