MDT Motor Diagnosis Toolkit Intelligent All in one Electrical Diagnosis Toolkit

MDT Toolkit is a portable motor driven equipment test system which automatically generates a condition assessment report indicating existing faults (both electrical and mechanical), time to failure information, recommended corrective actions, and effects of faults on energy efficiency. This unique instrument is capable of monitoring three phase AC motors and generators (as well as driven equipment) of all sizes and power levels to provide clear, unambiguous indications when the performance of a motor driven equipment begins to degrade. The toolkit uses three current sensors and three voltage sensors, making the system straightforward to install, and use without in-depth training of personnel. The test duration is approximately one hour allowing 7-5 tests to be performed in a day. Report is issued immediately at the end of the test.

WATCH EXISTING FAULTS These faults should bechecked for verification and corrective action should betaken at the next scheduled maintenance but no laterthan three (3) months.Mechanical Fault IndicationsMisalignment/imbalance. Check formisalignment, imbalance, bearing, coupling, andmotor shaft. EEE: Correct shaft alignment ensuresthe smooth, efficient transmission of power fromthe motor to the driven equipment.Vane/Trans. element/Driven equipment. Checkfor transmission element(s), coupling, drivenequipment, belt, pulley, gear box, and fan/pumpimpeller. EEE: Efficiency is dependent on pulley size,driven torque, under or over belting, and V beltdesign and construction. Efficiency deteriorates byas much as %5 over time if slippage occurs.

Electrical Fault IndicationsStator. Check stator for short circuit, windingslackness, isolation faults, and partial discharge.EEE: Heating and increased resistance due tostator, rotor and other electrical faults causedeteriorating conditions and reduced efficiency.WATCH ELECTRICAL VALUES Electrical values areoutside of their expected range. They should be notedand watched to identify the cause.Energy EfficiencyPower factor is below 0.80. If the equipment isworking under load then low energy efficiencymight have resulted from electrical faults. Monitorthe equipment efficiency.Current and Voltage ImbalancesVoltage imbalance exceeds %2. Voltageimbalance will cause heating and will result incurrent imbalance. EEE: Voltage and currentimbalances cause heat and up to %3 loss in energy efficiency.

AMU UNITS

Motor Diagnosis Toolkit (MDT) measures and pro-cesses three‐phase motorcurrent and voltage signals to generate an instant condition assessmentreport. MDT can be used with three phase AC fixed and variable speedmotors, induction motors, synchronous motors, and generators in low,medium or high voltage ranges.
