#Partial discharge (PD) measurement in transformer insulation is a diagnostic technique used to detect and evaluate localized dielectric discharges in the insulating system of a transformer. These discharges occur when the electrical stress in a localized region exceeds the breakdown strength of the insulation but is insufficient to cause a complete electrical breakdown. Some common patterns to evaluate PD results are described below.

partial discharge (PD） measurement of transformers as a means in predictive maintenance

This video is going to be Part 4 of 8 in a series which will go over the similarities and differences between insulation resistance testing and contact resistance testing. In this video I will talk about how to NETA testing on a simulated bus. Now I know some people are going to say, "you shouldn't demo that you can touch hot leads", and you are right. I did it for a point, which is that you will only get shocked when you close the circuit and you are a part of it. I am tired of the thought "red is hot and it needs to be on the test specimen and black on ground". Maybe that's how some of the older test equipment operated (and even hipots) but that is not how a digital meter functions. Point is, you need to understand your equipment. Additionally, discharging your conductors is important for your safety and for those around you. Not discharging conductors (like I have shown, or another method) can leave a charge on the cable or transformer, and when you or someone else goes to reconnect it, then you get shocked. Stay tuned for more in this series! The next video (# 5 of 8) will go over the DAR and PI with some nitty gritty details as well! P.S. I know my last post said this one will go over the DAR and PI . . . my apologies, its in number five of eight. #NETA #NICET #electricalmaintenance #testing #electricalsafety #electricalengineering #electricalindustry #powerdistribution #powertransmission #testingservices #training #teaching #electrical #team #tech #lovewhatyoudo

𝐈𝐦𝐩𝐮𝐥𝐬𝐞 𝐕𝐨𝐥𝐭𝐚𝐠𝐞 𝐈𝐧𝐬𝐮𝐥𝐚𝐭𝐢𝐨𝐧 𝐓𝐞𝐬𝐭𝐞𝐫𝐬 Impulse Voltage Insulation Testers are specialized instruments used to assess the insulation integrity of electrical equipment by applying high-voltage impulse waveforms. These testers simulate real-world electrical stresses, such as lightning strikes or switching surges, to determine the durability and performance of insulation systems under extreme conditions. These testers are essential for industries like power generation, transmission, and distribution, where the reliability of high-voltage equipment is critical. By ensuring insulation can withstand extreme conditions, these testers help enhance safety, reduce downtime, and extend the lifespan of electrical systems.

Current And Vibration Monitoring For Fault Diagnosis And Root Cause Analysis Of Induction Motor Drives. Thanks Bill Thompson & Phil Orpin for sharing. Abstract: Induction motor drives are the most widely used electrical drive systems and they typically consume 40 percent of an industrialized nation’s total generating capacity. In the USA the total generating capacity is approximately 800,000 MW, consequently induction motor drives are major assets in the process and energy industries. The asset management of electrical drives requires reliable maintenance strategies that include condition monitoring and online diagnostics. Due to the complex electromagnetic and mechanical characteristics of an electrical drive system, a unified monitoring strategy has distinct advantages over monitoring only one parameter (e.g., vibration) to diagnose problems. This paper focuses on industrial case histories to demonstrate the application of current and vibration analysis to diagnose problems in induction motor drives. The results show how the root cause of a problem can be established when a combination of current and vibration monitoring is used in comparison to only analyzing one signal. #Vibration #Current #Rotating #Equipment #Reliability #Motor
