5910 Portable
Short Haul Submarine Cable Test Set
The 5910 is a
portable Short Haul Submarine Cable Test Set that brings the latest
technology to the tried and tested DC methods of cable fault
location.
Common test procedures
which are associated with the location of cable fault such as
“open circuits” and “shunt faults” are pre-programmed into
the instrument. This allows the procedure to be carried out
automatically therefore eliminating operator errors and reducing the
uncertainty of fault position prediction.
|
|
The
instrument may be set for a range of voltages and currents making it
suitable for use with most un-repeatered submarine communication
cable systems.
The
RS232 interface is designed for full duplex communication with the
instrument. All functions may be controlled via a computer and
obtained data may be stored for future analysis. This interface may
also be used to enable two 5910’s to communicate with each other
via a computer when carrying out double ended tests such as “no
loss of current”.
|
|
|
|
|
A basic electroding
generator function is included which can assist the cable repair
vessel in locating the cable on the sea bed prior to retrieval and
repair.
A rack mount version the
Model 5910R is also available
