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.

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.
