Call of the Month for October 2024
A recent PQ Hotline inquiry from a PQ Knowledge (PQK) funder inquired about methods to detect defective cable splices and, in particular, if radiated emissions might be a useful approach. Cable/conductor splices are an essential part of modern electrical systems but represent a weak link and common point-of-failure, especially in underground cables. The question highlighted a critical issue for utility power quality (PQ) professionals: how can splices that are defective or otherwise nearing endof-life be detected efficiently to reduce costs and prevent service interruptions? Is there a method that could be applied to measure radiated emissions readily?

EPRI Industrial PQ Training Videos

As a follow-up to our Industrial Power Quality training classes, we have posted these complementary training videos to help solidify the concepts for both utility members and their customers. The top three are listed here.

Visualizing PQ Drive Parameters for Improved Voltage Sag Ride-Through 
This video demonstrates the voltage sag susceptibility of AC drive systems and how to improve the drive’s robustness through parameter changes.

Understanding PLC Voltage Sag Ride-through: AC and DC Powered Systems 
This video demonstrates the differences in voltage sag ride-through between an AC powered PLC system and a DC Powered PLC system.

Power Conditioning to Enhance Control System Voltage Sag Ride-Through: The Constant-Voltage Transformer 
This video shows how a CVT can be utilized to harden the voltage sag response of an automated control system.
