the infrequent operator
DESCRIPTION
Biddle ® impulse generators are de-
signed to locate faults in power cable
by the high voltage impulse method,
in which a high-voltage impulse is
transmitted down the cable to cause
the fault to arc. The arcing fault is then
pinpointed using an appropriate im-
pulse detector.
Biddle impulse generators may also
be used to perform voltage versus time
acceptance tests, or to burn faults that
fail to break down under impulse to
reduce their resistance. AVO offers
four models to meet every application:
15-kV Portable Model — This 75-lb
(34 kg) portable unit delivers 536
Joules for pinpointing faults on most
primary distribution cable rated to 15
kV.
AVO INTERNATIONAL
BRINGING RELIABILITY TO AMPS • VOLTS • OHMS
AVTB654 12/01 AVO INTERNATIONAL IS REGISTERED TO ISO 9001 STANDARD

Dual-Voltage Model — This 80-lb
(36kg) constant energy unit permits
up to 450 Joules to be discharged over
both the 7.5 and 15 kV ranges of the
unit.
Standard Model — This unit stores up
to 1250 Joules at 25 kV to meet the
requirements of a majority of applica-
tions.
Heavy-Duty Model — This powerful
unit, designed for van or substation
use, offers the highest impulse rating
in the industry. It delivers up to 5400
Joules at 30 kV (12
µ
F). A 24
µ
F option
is available which delivers up to 10,800
Joules at 30 kv.
APPLICATIONS
Biddle impulse generators pinpoint
faults on primary distribution cable
rated from 3.3 to 35 kV, including di-
rected buried cable and cable in
conduit or duct.
For faults that do not break down in
the impulse mode, a burn mode is pro-
vided to reduce the resistance so that
those faults will break down under im-
pulse voltage.
In addition to fault locating, these units
can be used as proof testers to check
the quality of insulation before and
after cable repair.
FEATURES AND BENEFITS
Biddle impulse generators offer spe-
cific benefits that ensure efficient,
effective and safe fault locating.
Rugged Construction
• Housed in sturdy metal cabinets us-
ing welded construction throughout
to withstand the rigors of field opera-
tion.
• Impulse switches use tungsten
ohmic contacts for extended life.
Simple Operation
• Modular control panels with a mini-
mum of controls and instrumentation
reduce operation complexity.
• Single lever operation mode selec-
tor eliminates the need to disconnect
and manually interchange high volt-
age output cables.
• High voltage and return leads are
combined in one coaxial cable elimi-
nating the need to unravel the total
length of test cable during operation.
