Kinetic Logging Services (KLS) is a geophysical logging service provider to the mining industry and part of a larger group MPC
Kinetic. KLS acquires data by lowering and retrieving instrumentation down the drill holes. They run a fleet of vehicles with high output 14V 220A alternators on the engine that provides DC power for our 230VAC inverters, electric winches, DC powered hydraulic power units, multiple air conditioning and hydraulic cooling thermo fans, computers and ancillary equipment.
Customer Problem
The systems on dual alternator equipped vehicles consume a high level of current of between 110A-300A+ (particularly the hydraulics up to 190A). Failure of one alternator can lead to the vehicle shutting down as the batteries are required to provide the additional
current required and they become depleted. The loss of an alternator prevents KLS from operating reliably and leads to lost revenue.
KLS needed a monitoring system to allow the vehicle operator to monitor the alternator operation and detect issues immediately.
Raztec Sensors Solution
KLS mounted two Raztec RAZFL-504MMCG sensors on the alternator output cables to monitor alternator current.
KLS used a programmable display with two analogue inputs, a 12VDC to 5VDC converter for the RAZFL-504MMCG supply and two RAZFL-504MMCG Moulded Current Sensors for the pair of 12V 220A alternators on the vehicle.
The display output was scaled to reflect the 0-220A out of each alternator. The new system has already been used to diagnose a faulty alternator.
“Our Raztec sensor equipped display allows our operators to rapidly diagnose alternator
faults saving time and money.”
