Types of Voltage Detectors and How To Select the Right One

Posted by Joseph Cardona on Jun 15, 2021 11:00:00 AM

In many cases, a line worker is faced with several daily tasks which require them to use a single-point-of-contact voltage detector. With a variety of options on the market, knowing which type to use for a project can be challenging. Hubbell Power Systems' CHANCE® Tools brand offers a wide variety of voltage detectors. When using a voltage detector, it is critical to always use a proper length hotstick that complies with company and OSHA-mandated minimum approach distances (MAD). Rubber insulating gloves should never be used as the only form of PPE when using a voltage detector.

Reducing Hazards of Step and Touch Potential

Posted by Joseph Cardona on Dec 28, 2020 2:00:00 PM

What is Step and Touch Potential?

While performing energized or de-energized line work, there are many opportunities for a line worker to encounter differences in electrical potential. Opportunities could include working near bucket trucks, underground gear, overhead switches, or in substations. When a difference in potential occurs across a worker’s body, current begins to flow. This current flow can be very hazardous as it only takes 50 to 60mA to become possibly lethal. These differences in potential can be categorized as step and touch potential. Step potential is defined as a difference in electrical potential between a worker’s feet and touch potential can be between a worker’s hands or hands and feet.

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.

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
