TEST INSTRUMENTS
Bierer VBI-15 Direct Contact Voltage Break Indicator
Provides an audible and visual alarm to indicate the absence of
voltage, with an operating range from 7.2kV to 20kV (Line to
Ground). An array of lights and an audible alarm to give the user a
quick and clear indication that the overhead line has dropped below
the threshold value of 2.5kV. Used by all forms of electrical entities;
investor owned utilities, municipalities, cooperatives,contractors,
etc. to track outages by individual crews at their location on the
system. Overload protected to 115kV for your safety. SAIDI and CAIDI
BIE-VBI15
ratings improve by quicker outage response time. Water Resistant for
inclement weather use. Includes a hook probe, instruction manual,
storage bag.

HD Electric APT-1 Active Power Tester
Is designed to give an indication when the absence of full line voltage
is detected on overhead conductors, giving an audible and visual
alert. The APT-1 is for use on uninsulated overhead conductors
with voltages from 7.6 to 13.2kV line-to-ground. Lets the worker
know whether the overhead voltage has been disconnected prior
to working on the line. Clampstick installed. Audible indication and
flashing light when the absence of voltage is detected on the line. 9V
alkaline battery Included.

Phase rotation indicator
Knopp K-3 Phase Sequence Indicator
Is used to determine the phase sequence (A-B-C or C-B-A) of three-phase voltages. (A-B-C is
clockwise rotation) It is important that phase sequence is known prior to energizing electrical
motors and other equipment, as incorrect connection could cause damage to the equipment.
The K-3 Phase Sequence Indicator is of the rotating-disk design; there are no lights to burn out.
All internal connections are soldered and there are no exposed metal parts on the housing.
Its three leads are color-coded (red (A), white (B), and blue (C)) for easy connection (other
colors are available upon request). The leads are 36 inches in length (other lengths available
upon request). The K-3 is designed for operation from 25 to 60 Hertz and from 60 to 600
Volts. Other models (including a panel-mount version and a 400 Hz. version) are available. A
description of K-3 variations can be found by clicking here. A rugged, nylon carrying case is
available as an option.
