protective device

The International Electrotechnical Commission (IEC) has released IEC 60755:2017.  This first edition standard applies to general safety requirements for residual current operated protective devices; and is now available on the IEC webstore.

Description: “IEC 60775:2017 provides general minimum requirements, recommendations and information for the drafting of standards on residual current operated protective devices (hereinafter referred to as residual current devices, “RCDs”). It applies to any device providing residual current protection intended primarily for protection against electric shock hazard.
This first edition cancels and replaces IEC TR 60755 published in 2008 and constitutes a technical revision.

Mastering High Voltage: The Importance of Accurate Test Equipment

This whitepaper underscores that precise calibration of high-voltage test gear — especially when measuring 1 kV–150 kV systems — is essential for safety, reliability, and regulatory compliance. It details measurement techniques (voltage dividers, step-down transformers, etc.), the impact of environmental and connection factors on accuracy, and why traceable calibration (e.g. to NIST / A2LA) is a must to ensure consistent, reliable results.

This edition includes the following significant technical changes with respect to IEC TR 60755:

a. restructuration of the document, as a Group Safety Publication, in compliance with Guide 104;
b. introduction of classification for type F RCDs;
c. introduction of Clause 9 for tests of RCDs (operating characteristics, electrical endurance, behavior in short-circuit conditions, trip-free mechanism, test device, surges, reliability, EMC).
It has the status of a group safety publication in accordance with IEC Guide 104
.
