Save Time and Money by Specifying the PCORE® Quick-Link Bushing

Posted by Mike Kryman on Sep 4, 2019 8:00:00 AM

Save time and money spent lowering the oil level in the transformer, when replacing higher current bushings, by specifying the PCORE® Electric Company, Inc. Quick-Link bushing.

In 1999, PCORE launched the first Quick-Link bushings that allowed electric utilities to save costs by significantly reducing transformer outage time. The design was further expanded to 115kV and 138kV in 2017. PCORE’s Paper-Resin-Capacitor (PRC) and Paper-Oil-Capacitor (POC) Quick-Link bushings have the following benefits:

How often should you calibrate your CHANCE® Meters?

Posted by Chad Davis on Aug 27, 2019 8:00:00 AM

CHANCE® meters are used to detect line voltage, determine approximate phase-to-phase-voltage, check DC resistance in protective grounding sets, determine in-or-out of phase relationships, monitor leakage currents, and advise the operating condition of CHANCE hot sticks. Calibration of these meters is important in confirming their accuracy in the field and ultimately in helping to protect line personnel.

Incorrect meter readings could result in undetected or misread voltages that could be harmful to equipment and personnel.

Experience Faster Testing with the PCORE® SET-Terminal

Posted by Mike Kryman on Aug 14, 2019 11:00:00 AM

The PCORE® SET-Terminal is designed for use with field dielectric test equipment for more accurate, faster, and safer field power factor measurement of apparatus insulation at a substantial savings.

PCORE Electric launched the SET-Terminal in 2011 as an addition to their test terminal line. The SET-Terminal provided improvements from the traditional porcelain test terminal that has been used by utilities since the 1950’s.  

Benefits of the SET-Terminal include:

  • A faster testing process.
  • Safer testing for test technicians.
  • Less expensive testing because of less labor hours and equipment down time.

Why Fiberglass Guy Strains are More Dependable

Posted by Chad Davis on Aug 1, 2019 3:00:00 PM

Fiberglass Guy Strains may be installed anywhere along the guy wire to help protect against stray current that may be on the guy caused by lightning strikes or other sources. These fiberglass units serve as a replacement for porcelain insulators or johnny balls, and they extend the insulation length. They offer numerous advantages, including:

  • variable lengths
  • easy terminations
  • resistance to fracture caused by brittleness

5 Steps Toward Keeping Cover-Up Like New

Download the Cover-up Care Guide

Here are five ways linemen can ensure their temporary protective cover-up equipment continues to function safely and for as long as possible:

  1. Take a close look every day

Don’t assume a cover is ready to use. Cover up may look fine at a glance, but it’s worth looking a little closer. Stretch out your rubber covers with a rolling or peeling action and look for cracks, scratches, moisture, or other defects. If you find something concerning, remove it from service and tag it to be tested or discarded.  Check the inside and outside surfaces as some defects may be hiding inside.

Understanding Distribution Arrester Types for Effective Equipment Protection

Posted by Haley Engel on Jun 4, 2019 8:30:00 AM

There are three distribution arrester types commonly used to protect overhead distribution equipment from the damaging effects of overvoltage. IEEE C62.11 defines Normal Duty (ND) and Heavy Duty (HD) classes by their ability to withstand certain current impulse levels. The third, Heavy Duty Riser is a type, or variation, of the HD classification and utilizes a larger diameter Metal Oxide Varistor (MOV) disc.

12 Steps to Install Square Shaft and Round Rod Anchors

Posted by Tim Staelens on Apr 17, 2019 3:09:00 PM
  1. Once all safety concerns have been addressed, attach the Kelly bar adapter and installing tool assembly to the Kelly bar on the installing truck.
  2. Insert the upper end of the anchors’ lead section into the installing tool. Position the anchor at the desired guy location and at a near vertical position; screw the first helix into the ground.
  3. When the first helix is buried, begin to make the angular adjustment for the desired guying angle.
  4. Remember, final angular adjustments should be made before the second helix penetrates the ground.
  5. When the installing tool becomes 12”-18” from the ground, disconnect it from the section in the ground and reconnect it to the next extension.

Maintaining your Anchor Tools

Posted by Tim Staelens on Mar 11, 2019 1:07:00 PM

As with most mechanical devices, CHANCE® anchor-installing tools periodically require maintenance checks to ensure peak performance.

TORQUE INDICATOR

In the case of the shear-pin torque limiter, (see drawing below to the right) you should be able to rotate the tool shear halves independently from one another using a smooth-turning action. If rotation cannot be done by hand or if movement is challenging, disassemble the torque indicator to check the thrust bearing, washers and/or pin for wear.
