IEC 61508 is an international standard published by the International Electrotechnical Commission (IEC) consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems.
An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not. The later requires a separate program to provide that feature, such as Qucs-S, [1] Oregano, [2] or ...
Variations in the electrical conductivity and magnetic permeability of the test object, and the presence of defects causes a change in eddy current and a corresponding change in phase and amplitude that can be detected by measuring the impedance changes in the coil, which is a telltale sign of the presence of defects.

The electrical safety develops with the technical progress. In 1989 OSHA [1] promulgated a much-needed regulation in the General Industry Regulations. Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. [2] In 1994 were established Electrical ...
Electrical Safety First (formerly the Electrical Safety Council, or ESC) is a registered UK charity working with all sectors of the electrical industry as well as local and central government to reduce deaths and injuries caused by electrical accidents. Research shows that every year 2.5 million adults get an electric shock in their homes or ...
