MIG16-2
Megger Impulse Generator and HV Test System
DESCRIPTION
The Megger impulse generator (thumper) MIG16-2 is
designed to provide quick, effective, accurate and safe fault
location, reducing system outages and customer minutes
lost.
The instrument comes in a rugged, yet portable,
enclosure. Its IP64 rating makes it suitable for use in even
environmentally hostile conditions.
The MIG16-2 offers the facility to undertake cable testing:
cable and fault diagnosis and pinpoint fault location using
acoustic methods.
FEATURES AND BENEFITS
High voltage module
n Easy-to-use manual controls
n Safety interlocks to prevent injury to operators
n Safety interlocks to prevent any switching during high
voltage generation.
n 2-ranges ensure 100% of energy available at 8 & 16 kV
n Powerful 1500 joules output assists rapid, accurate
pinpoint fault location even in difficult locations
n High visibility HV status bar
n External interlock
n Detachable HV cable
n Ergonomically designed transport handles and foot-step
allow for easy and comfortable transporation.
APPLICATIONS
HV testing (proof/insulation testing)
Used to prove the integrity of (and identify and confirm)
fault conditions in cable networks.
The variable output voltage can also be used for sheath
testing at 5 or 10 kV.
Proof/burn
Following a breakdown of the cable under test, a high
current is applied that stabilizes the fault condition. This
can assist pre-location and pinpointing of unstable faults.
Pinpoint fault location
Accurate pinpoint fault location is achieved using the
acoustic method, whereby the powerful 8/16 kV 1500-
joule surge generator (thumper) and an acoustic receiver
(Megger MPP2000) is used.
