HP72TM Hi-Pot Meter

Bierer’s Hi-Pot Meter is designed to perform a preliminary milliamp leakage
test on URD cable. The meter operates on two distribution voltage ranges:
7.6kV & 2.7kV phase to ground.
There are two selector toggle switches on meter, one on the back and one
on the side of the meter housing. The toggle on the back allows the user
to select between 7.6kV or 2.7kV. The selector switch located on the side
allows the user to test the meter before and after operation and also turn
on an LED back light for low light work conditions.
• Small and Lightweight
• Clear Analog Indication of “Good” or “Bad” Cable
• Much Safer Because Operator No Longer Has to Daisy Chain Primary
• One Year Warranty on Parts and Labor

HP72DCTM Hi-Pot Meter

The HI POT DEVICE is designed to HI POT de-energized 15kV class cables.
The tools transforms 18 volts from the Milwaukee battery to approximately
8,000 volts DC. When the battery is installed and the safety switch is in the
closed down position, the unit is in voltage detection mode. Unit should be
in this position when installing the device as it will sound a warning alarm
if you approach an energized source. When the safety switch is lifted and
the toggle switch is switched up, the unit is in the Hi-Pot mode and the high
voltage DC is being applied.
• Small and Lightweight
• Clear Analog Indication of “Good” or “Bad” Cable
• Much Safer Because Operator No Longer Has to Daisy Chain Primary
• No Primary Voltage Required
• One Year Warranty on Parts and Labor

The GT400HDXL provides quality testing for personal protective grounding
assemblies. The GT Series Grounding Assembly Testers are designed
to provide integrity testing of the electrical characteristics of portable
protective grounding assemblies. The GT Series Testers provide a reliable
test by administering Rated ASTM Current through the grounding assembly
and measuring the voltage drop across the assembly. The voltage drop in
conjunction with a thorough visual inspection determines if the grounding
assembly meets ASTM electrical specifications.
• Powered by Conventional 115VAC Outlet Rated at 20 Amps or Higher
• Transformer Allows ASTM Continuous Current to be Applied to Cable
• Compact and Easy to Read Reference Chart
• Optional Voltmeter for Checking Clamp and Ferrule Connections
• Easily Converts for Testing Elbows, Bushings, Mechanical Jumpers,
Substation Clamps, Truck Grounds and Cluster Grounds
• One Year Warranty on Parts and Labor

GRT1000A
Ground Resistance Tester 1000 Ohms
The GRT1000A is a major breakthrough for a traditional ground
resistance tester. It is widely needed in the power, telecommunications,
meteorology, oilfield, construction, industrial and electrical utility
industry. For a loop grounding system, the operator can measure the
ground resistance and test for continuity without having to break down
the grounding wire, or use auxiliary electrodes (sometimes referred to
as “stakes”). The clamp head is specially designed to reduce calibration
errors by increasing the clamp pressure and the robust design of the
transformers. The GRT1000A is able to read unwanted grounding
currents up to 15 Amps! It is safe, fast and simple to use!

3 Phase ID TransmitterTM
The 3 Phase ID Transmitter is designed to identify up to three shielded
conductors before and after the center conductor is exposed while
maintaining single or multiple ground connections. This unique tool features
a transmitter module that produces three different signals, indicating each
phase. The AVRCT, Audio Visual Receiver Current Transformer, a handheld
passive receiver, indicates the correct phase conductors for positive phase
identification, throughout the network. This device will significantly reduce
previously needed coordination resulting in time savings and eliminates
safety concerns by maintaining ground connections during the entire
process. The transmitter module is powered by two Milwaukee lithium ion
M18 batteries and incorporates cam lock connectors to quickly interface
different attachments such as C style, ball socket, alligator and 15 KV
elbows clamps.

Jumper / Grounding Cable

15/35kV Jumper Cables are manufactured with flexible stranded copper
conductors wrapped in semi conductive tape shielding to relieve voltage
stress and improve dielectric strength. Material is soft drawn electrolytic
copper meeting ASTM class B-33 to offer excellent durability and flexibility
under extreme operating conditions. A dual pass orange over yellow safety
insulator has a temperature rating of -56ºF to 194ºF. The insulating material
is composed of a thermo rubber compound and is designed to withstand
abrasion, temperature extremes, and submersion in water, oil, or acid.
Cable exceeds ASTM D752 and tested to ASTM D470 and ASTM F2321.
Made to order Jumper Assemblies
Copper Grounding Cable is available in yellow and clear, sizes #2,1/0, 2/0
and 4/0, it is extra-flexible for handling ease yet strong and tough for long
wear. Jacketing is smooth, abrasion, weather and oil resistant in accordance
with applicable ASTM Specifications, marked with AWG size approximately
every 4 feet. Yellow jacketed cables have a recommended low temperature
ratting of -20F while the Clear jacketed cable low recommended
temperature rating is 0F. All grounding cables meet ASTM F 855.
