Portable AC Hipot Test Sets

0-10 kVac, 0-30 kVac, 0-50 kVac and 0-100 kVac

Description

The PFT Series of portable AC hipot test sets are ideal for a variety of eld

and repair shop testing applications. These inexpensive, compact and light
weight units are rugged and reliable. Our 3 kVA models feature capacitive
load compensation enabling full load testing with a power draw of 1.5 kVA
while operating from a conventional line input.*

Applications

Model PFT-503CM

(0-50 kVac)

Model PFT-301CM

(0-30 kVac)

Model PFT-1003CM

(0-100 kVac)

These units are well suited for testing overhead apparatus, vacuum bottles
and interrupters, switch gear, bus duct, motorized vacuum switches,
reclosers, bushings, fuses and arrestors, linemans safety products, small
transformers, electrical components and motors.

For AC cable testing, we offer a variety of Very Low Frequency AC

hipots that are well suited for testing long cable lengths. Please contact our

sales ofce for more information on cable testing applications.

Control Features

Control features on our 3 kVA models include a dual range kilovoltmeter
and triple range output current meter. All of our units feature continuously
adjustable output voltage control, external safety interlock, zero start safety
interlock, self resetting over current protection, guard/ground return mode,
HV on/off and main power pushbuttons and ruggedized meters with glass
windows that eliminate static buildup.

An optional fault burning mode is available for our 3 kVA models and for

increased portability, a hand cart option is available for the PFT-1003CM.

Advantages

We offer four single piece, shielded output cable models: PFT-103CM,
PFT-301CM, PFT-303CM and PFT-503CM. A two piece 100kV model
PFT-1003CM with a top toroid termination (no output cable) is also
available. In addition, we offer an ALT-120/60 that is specialized for Aerial
Lift and Bucket Truck testing applications and suitable for general AC high
voltage testing applications. Custom models are available from 10kVac to
300kVac output.

Models below 100 kVac are single piece units with a shielded cable output for fast and easy test setup. The
PFT-103CM, PFT-303CM, PFT-503CM, and PFT-1003CM are compensated enabling testing of 3 kVA loads with a
power draw of 1.5 kVA and operate from a conventional electrical source*. In addition, these units include a dual range
kilovolt meter, triple range output current meter and a guard/ground return mode enabling the operator to measure the
total current to ground or only the current flowing through the sample under test.
