ETSI Releases Harmonized European Standard
ETSI EN 302 729-2 V1.1.2 specifies the requirements for Level Probing Radar (LPR) applications based on pulse RF, FMCW or similar wideband techniques.LPRs are used in many industries concerned with process control to measure the amount of various substances (mostly liquids or granulates). LPRs are used for a wide range of applications such as process control, custody transfer … [Read more...]
IEC Releases EMC Filtering Devices Standard
CISPR 17:2011 specifies methods to measure the radio interference suppression characteristics of passive EMC filtering devices used in power and signal lines, and in other circuits. The defined methods may also be applied to combinations of over-voltage protection devices and EMC filtering devices. The measurement method covers the frequency range from 9 kHz to several GHz … [Read more...]
IEC Releases Electromagnetic Environments Standard
IEC/TR 61000-2-5:2011 is a Technical Report intended for guidance for those who are in charge of considering and developing immunity requirements. It also gives basic guidance for the selection of immunity levels. The data are applicable to any item of electrical or electronic equipment, sub-system or system that operates in one of the locations as considered in this Technical … [Read more...]
FCC Proposes Rules Changes to Improve Wireless Coverage
The Federal Communications Commission adopted a Notice of Proposed Rulemaking (NPRM) to facilitate the development and deployment of well-designed signal boosters, which hold great potential to empower consumers in rural and underserved areas to improve their wireless coverage. Coverage gaps exist within those service areas and continue to pose a problem for residents, … [Read more...]
IEC Releases Semiconductor and Micro-Electromechanical Devices Standard
IEC 62047-12:2011 specifies a method for bending fatigue testing using resonant vibration of microscale mechanical structures of MEMS (micro-electromechanical systems) and micromachines. This standard applies to vibrating structures ranging in size from 10 μm to 1 000 μm in the plane direction and from 1 μm to 100 μm in thickness, and test materials measuring under 1 mm in … [Read more...]
IEC 61000-4-16 ed1.2 Consol. with am1&2
Electromagnetic compatibility (EMC) - Part 4-16: Testing and measurement techniques - Test for immunity to conducted, common mode disturbances in the frequency range 0 Hz to 150 kHz IEC 61000-4-16:1998+A1:2001+A2:2009, establishes a common and reproducible basis for testing electrical and electronic equipment with the application of common mode disturbances to power supply, … [Read more...]
IEEE Developing Standard Limiting Insertion of Harmonics into Power Grid
The IEEE Standards Association (IEEE-SA) Standards Board approved two new projects to develop standards that will limit the injection of harmonic frequencies into the public electric transmission system. Harmonic pollution is a growing problem caused by the widespread use of power supplies and other non-linear loads. It can result in power loss and equipment damage and it may … [Read more...]
IEC Releases Standard on High-Voltage Switchgear and Controlgear
Project IEC 62271-204 ed1.0, High-voltage switchgear and controlgear – Part 204: Rigid gas-insulated transmission lines for rated voltage above 52 kV, is an up to 3 months pre-release of the official publication. This part of IEC 62271 applies to rigid HV gas-insulated transmission lines (GIL) in which the insulation is obtained, at least partly, by a non-corrosive insulating … [Read more...]
New Standard Released on Electrical Insulating Materials and Systems
IEC/TS 61934 ed2.0, Electrical insulating materials and systems - Electrical measurement of partial discharges (PD) under short rise time and repetitive voltage impulses, is applicable to the off-line electrical measurement of partial discharges (PD) that occur in electrical insulation systems (EIS) when stressed by repetitive voltage impulses generated from electronic power … [Read more...]
