The Impact of Animal-Caused Outages

Posted by Darren Barnett on Sep 23, 2020 10:00:00 AM

The growing reliance on energy and the implications of its interruption in residential homes, commercial and industrial (“C&I”) facilities, and government agencies places an increasing burden on utilities to provide a more reliable power supply than ever experienced in the history of the electric system (see Figure 1).

Protecting America’s Birds with Greenjacket

Posted by Darren Barnett on Aug 25, 2020 8:00:00 AM

The Lemon Creek substation is a key site for AEL&P in supplying backup power and electrical distribution to the city of Juneau. It is located near a landfill, a food source attractant to many species of avians. AEL&P had been proactively investigating and testing several avian protection options available in the marketplace. These efforts helped, but there was still a need for further improvement. Following a significant eagle-caused outage that was reported on by the media, the Hubbell Greenjacket Team reached out to AEL&P to offer assistance in solving these issues.

The Importance of Lead Length for Arrester Applications

Posted by Ryan Freeman on Aug 17, 2020 1:00:00 PM

A commonly overlooked consideration in arrester applications is the impact of lead length. The inductance of lead wires can produce an inductive voltage drop which in turn will lower system protection. This voltage drop only occurs if the lead carries surge current and is in parallel with the equipment being protected. This resultant voltage is added to the discharge voltage of the arrester during a surge event, thereby reducing the protective margin of the system. The lead wire’s inductance is not strongly influenced by conductor diameter, but rather of overall lead length. Therefore, care must be taken to keep the lead length to a minimum in both distribution and substation applications.

How to Avoid Putting Strain on Fiber Communications Lines

Posted by Chad Davis on Jul 22, 2020 11:00:00 AM

When securing a fiber line to a pole, building or at mid-span, installers must be careful not to cause undo stress or strain on that fiber line. If they do, it can cause a break in the line, which in turn would cause an outage/disruption in service. Fixing this would be very expensive and time consuming, not to mention a huge inconvenience for everyone involved (contractor, worker, the public and customer).

Why Measuring Torque Matters

Posted by Tim Staelens on Jun 24, 2020 9:00:00 AM

The torque-to-capacity relationship for helical anchors and piles is an empirical method originally developed by the A. B. CHANCE Company beginning in the late 1950s. Today, the relationship is well recognized in the deep foundation industry. It is commonly referred to as torque correlation.
