There is always room for improvement. In electrical testing, this is particularly true because of the rapid development and application of the underlying electronics. Although a job may be proceeding with maximum satisfaction, it may well be made easier, faster, more accurate, and safer. For example, standby battery banks can develop ground faults over time through leaking electrolytes, accumulation of …
Communication is vital in everything we do, and it isn’t just the funny phrases at the end of the telephone game as kids. As NETA Certified Technicians, we must be familiar with different communication systems since they are essential to proper power system operation. In this quiz, we discuss some communication systems and associated components. Virginia Balitski, CET, Manager – …
Protection from hazards always begins with proper prior planning. An important aid to planning a job correctly and thoroughly includes using a tool known throughout the industry as a pre-job brief (PJB). These tools are commonly used at tailboards or tailboard meetings in construction parlance, but no matter what they are called, they are all designed to help you do …
Modern substation control and communication have revolutionized the ability to troubleshoot system faults and mis-operations. Event fault records and documenting every input and output provide invaluable information to help answer the question, “What happened?” However, there are hundreds of thousands of systems with legacy equipment. These systems can present seemingly baffling challenges that could necessitate several attempts (test and try) …
Grounding transformers are most frequently — but not exclusively — used in the renewable industry to provide a relatively low-impedance path to ground in case of surges. This allows for safe maintenance of the grid without fear of damaging the electrical infrastructure. If the grounding transformer is connected to a feeder, special considerations are required to set the protection to …
What does the future hold for our industry — especially when it comes to those all-important standards that ensure reliability, protect property, and help us to avoid injury or death? As we revise and update codes and standards from NETA, NFPA, IEEE, ASTM, NEMA, CSA, and OSHA, I think we should all read this very carefully, especially the summary. WHAT …
PowerTest 2023 in Orlando, Florida, was a smashing success. Many of us escaped snow, heavy rain, and freezing temperatures at home, making it easy to enjoy the sunshine and warm weather. Thank you to everyone who participated in the premier electrical testing and safety conference. In addition to excellent content, this issue of NETA World celebrates the recipients of NETA’s …
In the early days of protective relaying, it was recognized that communications between substations could improve relaying performance. Schemes such as power line telephony (1920s) and pilot wire relaying (1930s) evolved into digital time division multiplexers (TDMs) (invented in 1960s and used for power system communications in 1970s). TDM allowed audio teleprotection, audio-based relaying, SCADA, and telephony to share a single link …
January 27, 1939 — August 14, 2022 NETA and the electrical testing industry have lost another giant – Alan “Al” Peterson — whose influence across the industry and the love and respect he enjoyed from employees and friends point to a man with rare talents. Al received his formal education in electrical engineering at Northeastern University in Boston and completed …
March 26, 1939 – September 24, 2022 One person can make a difference, and everyone should try. William Barclay said, “There are two great days in a person’s life — the day we are born and the day we discover why.” On March 26, 1939, Peter Alan “Pete” Sherman was born, and it was a great day. Bigger than life …
