DESCRIPTION
AC and AC/DC High-Pot Testers available from Megger are
designed for safety and ease of operation, and readily adapt
to development, maintenance or production testing. Three
models are available: two ac and one ac/dc. The AC High-Pot
Testers feature a front-panel, NEMA 5-15R three-prong
output receptacle. Booted, alligator-clip output and return
probes are also supplied with all models.
Test voltage is continuously adjustable from zero to full
output, with a zero-start interlock. Leakage current trip
level may be adjusted from 0.3 to 12 mA by a front-panel
knob. Pushbuttons are provided to select one-second or
continuous testing, to turn off the high voltage and to reset
the instrument. All high-voltage connections are recessed
to prevent accidental contact with high voltage.
During testing, high voltage will automatically shut down
within 50 ms of arcing or exceeding the preset trip level.
Visual and audible alarms alert the operator upon failure.
The instruments also feature an interlock that prevents the
high voltage from being applied if the supply ground wire
is open or if the hot and neutral wires are interchanged. A
Tester Grounded lamp lights to confirm the instrument is
connected to a properly grounded power source.
The AC High-Pot Testers will automatically shut down if
ground circuit resistance of the test object exceeds 15
ohms at any time during testing. This feature may be
bypassed when testing double-insulated devices or when
using test probes. The AC/DC High-Pot Tester provides a
slide switch to select either ac or dc test voltage. The slide
switch safely covers the output jacks not in use.
APPLICATIONS
These portable instruments are used to test the dielectric
strength of electrical insulation and the ground circuit
continuity of three-wire appliances and other devices.
Biddle High-Pot Testers comply with most existing UL
requirements for dielectric withstand testing, including:
■ UL 544 – Electric Medical and Dental Equipment
■ UL 982 – Motor-Operated Household Food Preparing
Machines
■ UL 1026 – Electric Household Cooking and Serving
Appliances
■ UL 1270 – Radio Receivers, Audio Systems, and
Accessories
FEATURES AND BENEFITS
■ Ground continuity check of three-wire devices with
high-voltage interlock (ac models only)
■ Front-panel adjustable leakage current trip from 0.3 to
12 mA
■ One-second or continuous testing
■ Automatic failure shutdown, with visual and audible
alarms
■ Recessed high-voltage connections
■ Front-panel NEMA 5-15R three-prong receptacle on ac
models
■ Zero start/reset in event of failure
■ Meets UL 120-k? requirement
