CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ Section 1 - OPERATIONAL 1.1. Environmental Considerations Seismic Sound Sources and Marine Life Although not proven, there is concern in some quarters that marine mammals may be harmed or their behaviour changed by seismic activity. The sound pulses from sparkers and boomers is much lower in amplitude and higher in frequency (so it will travel less far) than air guns.
CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ 1.2. Introduction The CSP-N is an evolution of the CSP-D range of seismic power supplies. The CSP-N has a high voltage charger rated at 2000 joules per second, and can supply up to 1200 or 2400 joules of energy per shot into the seismic sound source for example Dura-Spark.
CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ 1.3. Installation Siting the CSP-N The CSP-N deliver high energy, high voltage pulses, yet still emit minimal electrical emissions, and so can carry the CE mark. The CE marking ensure that the CSP-N can be sited next to sensitive electronic equipment which carry their own CE marking (for susceptibility to emissions) and will be unlikely to cause them interference.
CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ Earthing The CSP-N MUST be earthed. The M8 earth bolt on the front panel should be connected to the vessel earth by a heavy gauge wire or cable. On larger ships, earth is usually a steel bulkhead, but for smaller fibre glass / wooden vessels a sea earth is necessary.
CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ Installation The CSP-N Unit will normally be supplied from the factory in a ‘Hardigg’ transit case. As is the case with all electronic equipment, care should be exercised in handling. For maximum airflow in high ambient temperatures it is recommended that the anti-vibration housing rear panel be removed.
CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ Output Cable Connection Continued In the situation of the power cable / sound source being caught on an object, the HV cable is pulled from the HV Junction Box, rather than the CSP-N unit being pulled onto the floor. The junction box is usually supplied with a 1.5 metre lead, terminated in our HV connector.

CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ Operation of the CSP-N with a Boomer Sound Source A boomer plate as a sound source produces a single pulse and the amplitude and duration of this pulse is controlled by the energy going into it. The energy is derived from the voltage and the quantity of energy stored in the CSP unit.
CSPN Capacitor Charging Unit Operation Manual CSP-CSPN-8000/1 __________________________________________________________________________________________________________ Operation of the CSP-N with a Sparker Sound Source The CSP-N is designed for use with the Dura-Spark Sparker. The CSP-N is not compatible with the Squid Sparker range of sparker sound sources due to the polarity of the power supply. The polarity of the CSP-N reduces tip wear to a minimum ensuring a stable repeatable sound source.

In this way the operator can see if the unit is being run faster than the charger can cope with. If the operator notices loss of data on the recording system, it may mean the CSP-N is being fired too quickly, not allowing the capacitors to charge to their full potential.
