HD Electric DVI-500 Digital Voltage Indicator
HD Electric HALO II® High Voltage Digital Ammeter
Are single point instruments designed to read the voltage on a conductor up to 500kV line-to-ground. The large LED readout is easy
Is for use on power distribution systems designed to take True RMS AC current measurements. Its
displaying the voltage on a large 3-digit LED display. The DVI-500T with Test Point Mode has the added feature of indicating voltage
a single phase, as well as take readings on all three phases to determine load balance. The HALO
to read on the end of a long hotstick and can be used on overhead lines or in underground applications with an underground bushing
probe. There are two DVI-500 models. The DVI-500 indicates voltage from 0.1kV - 500kV on overhead and underground systems on elbow test points. The DVI displays the voltage and emits an audible alarm when voltage above 100VAC is detected with no range
selector switches or settings to be made - just contact the conductor and read the display. This allows the user to determine if the
voltage being read is nominal or a lower induced voltage.
HDE-DVI-500
Digital Voltage Indicator
BIE-ST800
open-core design allows the user to quickly hook it over a conductor from the end of a hotstick and
obtain a current reading in amperes. The HALO can be used to take spot load measurements on
II includes the peak-hold mode and also a tracking mode that allows the user to view continuous
changes on the display. The unit can be used on any voltage up to 69kV system voltages. Fork-style
sensing head. The HALO can be used over insulated cable. However, it cannot be used over shielded
cable, such as the concentric neutral.
High Voltage Ammeter Features:
• For use on voltages up to 69kV class (40kV line-to-ground)
HDE-9391

HD Electric High Voltage Ammeter, 25 to 500Hz, LED
An oscilloscope is vital for diagnostic work, and not just to determine voltage or resistance. Since it
allows for the waveform to be viewed in real time the frequency can be quickly calculated revealing
dips and spikes in the power source. Take a look at the features for Hde High Voltage Ammeter.
Includes: Tool and bag.
HDE-HVA-2000H
Bierer ST800 Service Tester
Are single point instruments designed to read voltages up to 800 amp service. Puts a high magnitude pulse between the neutral/
hot leg or hot leg/hot leg for any secondary service. It cannot be fooled by telephone and cable television bonding often missed by
continuous loading devices. Identify bad conductor(s) from the transformer to the meter base. Indicate integrity of neutral conductor
to prevent excessive house ground currents. Locate both hot legs and neutral at the pedestal and/or transformer blocks. Locate bad
connectors on overhead spans. Identify de-energized URD Primary cable in a manhole or ditch. The large LED readout is easy to read.
