Sparker Load

A sparker consists of a number of electrodes in the (salt) water which creates a sound
pulse as the plasma bubble expands. The current into a sparker varies with cable length
and type as well as by the number of tips and the salinity of the water. Typical values are
shown below for AAE sparkers in standard seawater with a salinity of 35 ppm.

Dummy Load

AAE manufacture a dummy load with precisely designed characteristics which can be
used for testing of CSP-S

units in the workshop to avoid ‘water based dummy loads’

such as dustbins full of salt water etc!

Please check with other sparker manufacturers whether their sparkers are compatible
with the specifications laid out in this manual.
