Current Interrupter | Close Interval Potential Surveys | Cathodic Protection

Pulsar GPS Current Interrupter

The PULSAR is a compact, battery or AC power driven, current interrupter device to be used when carrying out Close Interval Potential Surveys (CIPS), Direct Current Voltage Gradient (DCVG) and Test Post Polarised Surveys. The pulsar uses the latest solid state switching components, microcontrollers, GPS electronics and operating software. It has been designed so that it is easy to program and operate, yet rugged enough to resist harsh environments such as deserts.

The PULSAR has been designed to replace traditional type current interrupters and by using a GPS current interrupter device the operator can be confident of an accurate survey.

The Pulsar is available in 2 units – the handheld unit is enclosed in a rugged aluminium housing which is batteries or mains operated (with a Pulsar PSU) and contains an integral 50A switching element. The second option is an aluminium housed Panel mount unit for integration within Transformer Rectifier unit. The slave switching element is external to the panel enclosure to allow flexible integration within the design of the Transformer Rectifier unit. The slave switching units are available in 50A and 150A units. The handheld Pulsar is capable of operating an external slave switching unit.

The start and stop time can be set on the days for surveying with a minimum switching time of 1 hour. When the Pulsar is not switching the output remains “On” to maintain protection. When the battery life is low, the pulsar output is switched to “On” and the unit goes into a low power mode.

The timing resynchronisation with the GPS can be adjusted to preserve battery power.

The units are available in purpose built cases where 2 sizes are available, 2 or 4 Units allowing ease of transportation while also allowing protection of the units from damage.
