I applied via Company Website and was interviewed before Aug 2023. There were 4 interview rounds.
IEC/IEEE standards provide guidelines for addressing power quality issues in testing.
IEC 61000 series provides standards for electromagnetic compatibility (EMC) testing
IEEE 1159 standard focuses on monitoring and analyzing power quality
IEC 61000-4-30 standardizes measurement methods for power quality parameters
Compliance with these standards ensures reliable and accurate testing results
PQ harmonics refer to the quality of power in electrical grids, including voltage and current harmonics.
PQ harmonics are regulated by grid codes to ensure the quality of power supplied to consumers.
Grid codes specify limits on harmonic distortion levels to prevent negative impacts on equipment and systems.
Examples of grid codes include IEEE 519 and EN 50160.
Harmonics can cause issues such as overheating in transformers
Yes, application software for power quality and energy metering monitoring works effectively.
Application software can effectively monitor power quality and energy metering data
These software can provide real-time data analysis and reporting
Examples include Power Monitoring Software, Energy Management Software, and Smart Metering Software
Present organization at PQ issues encountered? How mitigated,which PQ devices or analyzer used,How it's reported in software etc
I applied via Naukri.com and was interviewed before Jun 2023. There were 3 interview rounds.
