A new approach to cable diagnostics is discussed in the
present paper. It combines the advantages of testing with
variable frequency over non standard wave shapes for
commissioning and diagnosis on cable systems with a partial
discharge measuring system based on the apparently well
assessed measurement and location of partial discharges
activity in cables, but with innovative and substantial
diagnostic value added.
The different methods for

Megohmmeters
Megohmmeters generate high voltage, low current signals for testing the breakdown strength of electrical insulation. They are called megohmmeters because the insulating resistance of a properly designed product is expressed in mega ohms (MOmega: Ohms ).
