 
Hi, I'm Ken Rousseau a Sales Engineer
for Haefely Hipotronics. Today I'm gonna take you behind the scenes to do a live test
with our 800 PL series
portable DC hipot testers.
Here at Haefely Hipotronics
we always stress the importance of safety
so be sure to check with your own company's
safety guidelines for personal protective equipment.
This unit is our 880 PL DC hipot tester. It's capable of putting out 80 kV
at ten mA. Other models in the 800 series
follow similar testing procedure, but today I'm
gonna demonstrate testing on a
15 kV rated URD cable.
While the power is off, connect your AC power supply
to the unit,
and your 120V/60Hz power strip.
Also,
connect your high-voltage, return, and ground leads.
Then connect the other ends of your leads back to the unit.
Also be sure your interlock plug is connected.
Now it's time to make sure that all nonessential personel are out of the testing area
so you can begin your test.
set your current range to max
and set your voltage range to the desired setting.
My cable is only rated to 15kV, so I'm going to use the lowest
0 to 20 kV setting. 
Make sure your voltage control
is lowered all the way to zero. 
Turn on the AC power switch
and this beacon will light up to indicate that there is power to the unit
From a safe position, turn on your high voltage. This beacon will light red
indicating that you are ready to start your test.
Slowly raise your voltage
to your desired setting for me
that's gonna be about 13 kV
You can hold you voltage for as long as your test specifies.
Now that the voltage is on my device under test
I'm gonna check the leakage current on
the current meter.
Right now the current meter range
is set from 0 to 10ma. 
As you can see
it's nowhere close to 1 milliamp 
so I'm going to
adjust the current range to go into microamps.
As you can see
we've got about four micro amps of leakage current
Now, I'm going to readjust the current range
to the 0-10 milli amp range
My test has run long enough. 
So I'm going to go ahead and slowly lower my voltage back down.
I'm going to turn my high voltage off,
and my AC power off.
It's important to make sure that you unit is
properly grounded,
so I'm going to use a grounding stick.
Now you are ready to disconnect your specimen.
and pack up the 880  for another test
to recap set up your testing area
connect the AC power to the unit
connect your high-voltage return and ground leads
 
be sure that the interlock plug is in
place. Set the desired range on the
Set the desired range on the current meter
and the voltage meter. Check to make sure
the current meter dial
is at 10 mA and the raise voltage control is at 0
power on the unit using the AC
power switch
engage the high voltage by pressing the
HV on button.
Perform the test. raise the voltage control to the desired level for the desired time
observe leakage current adjusting the
current meter to a more accurate range
as needed
complete the test reset the current
meter dial to ten mA
lower the voltage back down to zero. Turn
the high voltage off
and the AC power off. For safety
use a grounding stick to ground the specimen under test.
