DOUBTS IN THE INTERPRETATION OF IEC STANDARDS? Post here and I write my interpretation. Standards sometimes are confusing. An example is IEC614391/2. A revision of Table 6 for temperature rise limits could make it understandable by testing labs like IEC62271-1 is. Also, a figure showing the intended test circuit should be included. No lab I know understand the circuit to use * (one source? many sources?) (*) . If you have a doubt about any IEC standard part post it here with sufficient information.  ( * ) article link https://lnkd.in/dHbQzHy3 ** #training #electryindustry #IEC62271 #IEC61439 #iec61641 #switchgear #switchboard #iec60943 #ul #iec #ieee #ansi #copper #aluminum #substation #bysergiofeitozacosta

Have you caught up on the latest changes to IEC 60079-14? The 6th Edition of IEC60079-14 brings forward significant updates to electrical installation standards in hazardous areas, and it's crucial for professionals to be aware of these changes. The CompEx Standard Guide provides a comprehensive analysis of the most significant updates. It's purpose is to summarise the most noteworthy changes and includes an easy to follow mapping section that helps cross reference clauses from the 5th edition to the new 6th edition. Read the standard guide here: https://lnkd.in/ejqtF2ac Paul Hague #IEC60079-14 #HazardEx #HazardousAreas

For those Hazardous Areas industry professionals looking to become more familiar with the recently released 6th Edition of IEC 60079-14. Get yourself a copy of this really useful guide we have produced at CompEx to assist you in navigating the layout changes found in this update to the standard. Particularly useful (for me) as well as focusing on the key updates, is an old to new mapping section that signposts to where their location is found within the new structure of this new edition for those who are very familiar with the clauses found within the previous edition 5. **Worth noting for those who currently use the BS EN 2014 version of 60079-14 this is currently due to be released as a fully adopted BS EN IEC standard in December according to the BSI Website. https://lnkd.in/edwzDFZj Effectively meaning it should be (other than the likely insertion of a national foreword) word for word exactly the same throughout. #HazardousAreas #ExplosiveAtmospheres #Standards #ElectricalSafety #CompEx

Ok IEC (International Electrotechnical Commission) you are stating IP means ingress protection but Institution of Engineering and Technology (IET) in BS7671 (p48 abbreviations) state it means international protection Please can someone finally clarify what IP stands for? Is IEC correct or is IET and bs7671 correct ? It’s a real debate as we all go by BS7671 but who is correct?

👉 What is IEC 61000-4-30? IEC 61000-4-30 is an international standard that defines the methods for measuring and interpreting power quality parameters in a.c. power supply systems. Let me break it down for you: 1. Purpose: The standard provides guidelines for accurate and repeatable measurements of various power quality parameters, ensuring reliable results regardless of the instrument used. 2. Frequency Range: It covers conducted phenomena in power systems with a declared fundamental frequency of either 50 Hz or 60 Hz. 3. Parameters Covered: - Power Frequency: Measurement of the fundamental frequency of the supply voltage. - Magnitude of the Supply Voltage: Determining the voltage level. - Flicker: Assessing voltage fluctuations. - Supply Voltage Dips and Swells: Detecting sudden voltage changes. - Voltage Interruptions: Identifying voltage dropouts. - Transient Voltages: Capturing rapid voltage variations. - Supply Voltage Unbalance: Evaluating voltage imbalances. - Voltage Harmonics and Interharmonics: Analyzing harmonic content. - Mains Signaling on the Supply Voltage: Detecting any signaling superimposed on the voltage. - Rapid Voltage Changes (RVC): Measuring abrupt voltage transitions. - Current Measurements: Now a normative method (previously informative). 4. Additional Considerations: - Emissions in the 2 kHz to 150 kHz Range: Addressed in informative Annex C. - Over- and Underdeviations: Covered in informative Annex D. - Class A and Class S Measurement Methods: Defined and clarified. - Class B: Moved to informative Annex E and considered for future removal. - Responsibility for Influence Quantities and Test Procedures: Transferred to IEC 62586-2. This standard ensures that power quality instruments provide consistent and reliable results, making it essential for monitoring and predictive maintenance of equipment. 🤠 #mrelectricianaip
