The purpose of the sync check function (25) is to ensure that the voltage magnitude, phase angle, and frequency of the generator (VX) and the utility system (VS) are within a set of acceptable limits before the generator is synchronized with the system via closing the circuit breaker that connects them (Figure 1). An improper sync can result in electrical …
Summer is in full swing across the country, and I want to take some time to focus on safety. You’ll find many of our articles in this edition of NETA World revolve around some aspect of safety. Our cover story continues the discussion of the 2018 changes to the arc flash calculation process in IEEE 1584. (Editor’s note: Catch up …

ANSI/NETA ETT–2022 REVISION COMPLETED ANSI/NETA ETT, Standard for Certification of Electrical Testing Technicians, has completed an American National Standard revision process. ANSI administrative approval was granted January 7, 2022. The new edition was released at PowerTest in March 2022 and supersedes the 2018 edition. ANSI/NETA ETT establishes minimum requirements for qualifications, certification, training, and experience for the electrical testing technician. …
“People who are trying to change the world need to use checklists.” BUSINESSMAN AND AUTHOR GUY KAWASAKI Checklists and effective job briefings are important to ensure hazards that may exist when performing a task are addressed before starting the job. In addition, job briefings are important to ensure people understand their job roles and have a chance to speak up …
Mentoring has been a critical and foundational component in the electrical sector since its beginning. The basic tenants of electrical tradesperson apprenticeships and electrical engineers in training has always been coaching and mentoring by those with the interpersonal skills, relevant expertise, and knowledge to be able to pass it on. The electrical sector has always taken particularly great pride in …
It’s happened to nearly everyone. You go to use a simple electrical device…a flashlight, a voltmeter, a TV remote, or a child’s toy…and the battery is dead. It has become exhausted and must be replaced. Or worse, you open the device to find that the battery has corroded, possibly damaging or even destroying the contacts. In some critical respects, essentially …
In gas-insulated substations (GIS), the high-voltage elements, including conductors, circuit breaker interrupters, switches, current transformers (CTs), and voltage transformers, are encapsulated in SF6 gas inside grounded metal enclosures.[1] For that reason, direct access to circuit breaker (CB) main circuit terminals for testing purposes is not possible. The inaccessibility of main circuit terminals requires several actions to be taken before conducting …
The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective relaying demands the utmost attention and diligence. However, when dealing with relay protection, protection engineers may inadvertently focus only on the relays. Engineers talk about selecting appropriate relays, applying correct settings, checking out …
