Cover-Up Equipment: Selection and Care

Posted by Joseph Cardona on Sep 24, 2020 8:00:00 AM

Hard Plastic vs. Rubber Cover-Up Equipment

Deciding which cover-up equipment is best for the job depends on several factors, including the system voltage, types of energized equipment, and work methods (rubber gloving vs. hotsticking).

Understanding Classes and Types of Rubber Insulating Blankets

Posted by Joseph Cardona on May 26, 2020 8:00:00 AM

Insulating rubber blankets for energized line maintenance come in a variety of sizes, classes and types. Each Class of insulating blankets has its own maximum use and testing voltages, as described in ASTM D1048 (see Table 1). The higher the class rating, the higher maximum the voltage rating is for the insulating blanket.

Why Use “H” Rated Clamps for Temporary Grounding

Posted by Billy Webber on Feb 28, 2020 10:42:09 AM

Prior to 2009, ASTM F855, Standard Specifications for Temporary Protective Grounds to Be Used on De-energized Electric Power Lines and Equipment only included one table indicating the specifics to which ground set designs were to be tested. This “Table 1” was based on a near symmetrical current, limiting the circuit inductive reactance to resistance (X/R) ratio to a maximum of approximately 1.8 (20% asymmetry).

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.

Make a Smart Choice with a Smart Tool

Posted by Chad Davis on Jul 11, 2019 8:00:00 AM

No more squinting to read the voltage from the end of the hot stick – or relaying information to the crew on the ground. The new CHANCE® Transmission Multi-Range Voltage Indicator® (TMRVI), lets your entire team accurately monitor transmission voltages on a mobile device or Apple Watch using the free MRVI app with an easy-to-read interface.

5 Steps Toward Keeping Cover-Up Like New

Posted by Joseph Cardona on Jul 2, 2019 2:45:33 PM

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.

13 Steps to Replace an Insulator on a Tangent Structure

Posted by John Delsman on Jan 14, 2019 10:48:00 AM

The safety procedures described below are the basic steps and necessary equipment linemen will employ when replacing an insulator from an aerial lift truck on a tangent structure with rubber gloves.

  1. A hold-off is recommended on the line to ensure the line is locked out after an automatic protection operation.
  2. A tailboard briefing is held with all workers before the work starts to ensure all procedures are understood.  Proper safety precautions should be observed. Each person should know specifically what they are required to do. All workers should

Cleaning & Inspecting Your Gloves in the Field

Posted by Joseph Cardona on Oct 24, 2018 3:26:00 PM

Properly inspecting and storing your rubber insulating gloves could save your life. Rubber insulating gloves are the first line of defense against electric shock. ASTM F496 requires that rubber insulating gloves be inspected and electrically tested at a maximum interval of every six months, whereas field inspection is necessary prior to each use. The date code on the rubber insulating gloves should be checked to verify the most recent testing of gloves is still valid.
