Connection
Make sure the power of both the Midas and the Resonating Inductor 5289 is Switched OFF
before connecting them together.
The earth cables should be the FIRST leads to be connected to the equipment. The unit itself
is also earthed over the outer shield of the HV Input cable and the PE pin of the mains cable.
The Midas must be switched ON FIRST – after the Midas is powered you can switch on the
Inductor.
Do switch OFF the Inductor FIRST - after that the MIDAS system can be switched off.
The earth cable should be connected to the Earthing Screw on the bottom of
the 5289 and the ground at one end and to the station grounding system at the other end.
Connect the MIDAS “HIGH VOLTAGE OUTPUT” with the
supplied short yellow HV cable to the “HV In” of the Resonating
Inductor.
Connect the test object to the “HV Out” of the Resonating
Inductor with the standard yellow HV cable (20m) of the
MIDAS.
Check all the wiring and please be aware of the fact that during
a measurement high voltages and high current (15 kV, 5 A) are
involved.
If the DUT load is SMALLER than 250nF, connect the
baseload capacitor:
-
HV cable to HV connection on DUT and to top end of the cap
- Gray cable to banan plug on bottom of the cap,
- Yellow/green cable to the earth stud and the earth stud
(bottom plate)
- Earth stud of bottom plate to the station grounding system.
