BIDDLE IMPULSE GENERATORS
Dual-Voltage Model
(Catalog #651016)
For power without pounds, this light-
weight constant energy unit features
dual voltages to permit up to 450
Joules to be discharged over both a
7.5 and 15 kV range. On the 7.5 kV
range this unit utilizes a 16
µ
F capaci-
tor which produces an extremely loud
“thump” at the fault.
This model is designed primarily for
direct buried cable in applications
that require instrument transport
without a truck or van.
Specific capabilities include:
• On the 7.5 kV range, it can be used
on 5 kV class cable without a reduc-
tion in signal energy.
• On the 15 kV range, it is sufficiently
powerful to locate faults on 15 kV
class direct buried cable.
• The 25 kV proof mode permits main-
tenance testing of 5 kV class cable.
• The 25 kV/30 mA burn mode per-
mits simple breakdown testing and
fault resistance reduction to locate
faults on 15 kV class cable.
Standard Model
(Catalog #651028)
For a broad range of application capa-
bility in a portable instrument, this
unit delivers 1250 Joules at 25 kV. Al-
though this unit is heavier than the
15-kV and dual-voltage models, it is
still portable for convenient transport
to remote sites. The energy output
makes this unit effective on direct bur-
ied cable and simple conduit circuits.
Standard Safety Features
• Isolated high voltage output cable
• Zero-start voltage interlock
• High voltage ON lamp
• Automatic grounding upon shut-
down
• Redundant ground connections
• Manual grounding of capacitor and
cable by Mode Selector for safety.
• Viewing window to confirm internal
grounding system
• Circuit breakers for overload pro-
tection
• External interlock provision
• Meters remain active even when
power is off
Continuous Voltage Control
• Allows full adjustment of output
voltage over the impulse and proof/
burn range
• Limits the output voltage to the
minimum necessary for breakdown
Maintenance-Free Operation
• Quality components and construc-
tion assure ongoing reliable operation
15-kV PortableModel
(Catalog #651017)
For lightweight economy, this 75-lb
(34-kg) instrument discharges 563
Joules at 15 kV.
Specific capabilities include:
• It will locate all faults on 15-kV class
direct buried cable.
• Its 25-kV/30mA burn mode is handy
for simple breakdown testing and fault
resistance reduction on cables up to
15 kV.
Specific capabilities include:
• With a 25-kV impulse voltage out-
put, it finds faults on 15, 25 and 35 kV
class direct buried or “in conduit”
cable.
• The 30 kV proof mode permits ac-
ceptance testing of 5 kV class cable
and maintenance testing of 8 kV class
cable.
• The 30 kV/50 mA burn mode per-
mits simple breakdown testing and
fault resistance reduction to locate
faults on 25 kV class cable.

Heavy-Duty Model
(Catalog #653031)
This model offers the highest impulse
rating in the industry. When using the
optional 12
µ
F reserve capacitor, it can
deliver a discharge of 10,800 Joules at
30 kV intermittently. This option pro-
duces a louder “thump” at the fault
site resulting in locating success at
lower voltages.
This model features skids for standard
mounting in a van, trailer or truck, and
can be optionally caster-mounted for
station use.
This unit is designed for heavy-duty
applications such as complex network
circuits and faults located in pockets
of water and oil. It will find virtually all
the faults in primary distribution
cable.
Specific capabilities include:
• With its 3750 or 7500 Joule at 25 kV
impulse voltage output, it can find
faults on 35 kV class direct buried
cable or in conduit or duct.
