Overview; Working Principle - Made JUPITER PLUS User Manual

2. OVERVIEW

2.1.Working Principle

 Identification of cables in a trench, gutter and in cable shelf.
 With short-circuited ends
 Identifying the phases and checking cable continuity to
transmitter S1
 With short-circuited ends (closed circuit)
 With open-circuit ends.
The configuration required for each of these modes is described in
this document.
Each of the functions is usually carried out on unpowered MV & LV
cables (customer loads on-line).
The signals and the physical principles used are common for each
function.
The JUPITER system is made up of a Transmitter and a Receiver.
The Transmitter is in a shock-proof carrying case which also
contains the various accesories. The connector for the current
injection clamps is on the front face of the Transmitter.
The Receiver is in a soft carrying case which fits into the Transmitter
case. This also contains the 3 sensors used for cable and
conductor/phase identification:
 Cable identification
 Continuity and core identification in open circuit.
 Continuity and core identification in short circuit
