Contractors in Sandton, Engineers in Sandton

M&C has the ability to design products to suit your specific needs. Design changes can be implemented on existing motors in order to improve efficiency and/or power factor and to deliver improved reliability. Detailed recommendations for the repair with specifics of engineering improvements. M&C’s global on-site electrical and mechanical engineering services. M&C offers a wide range of products and reactive maintenance services on-site, minimising your downtime and helping to maintain or improve productivity. To be recognised as the first choice service partner for all electrical and mechanical rotating equipment. Marthinusen & Coutts is the proven partner to help you achieve this. Your peace of mind relies on having a partner who takes long-term responsibility for maintaining your productivity. M&C offers a full range of maintenance services for your rotating electrical and mechanical machines. Engineering design, evaluation and development for improved performance, efficiency enhancements and power savings etc. Our test capabilities are structured around sound engineering principles and international specifications. This culminates in many non-standard advanced tests being performed on a regular basis in order to ensure full compliance with local and international as well as customer specific standards. Winding resistance: Test measurements are recorded using high accuracy four-wire, high capacity resistance bridges. This equipment not only measures the insulation resistance value, but also displays the actual test voltage. This ensures that any possible inter-turn or inter-phase shorts are detected prior to VPI or on final test. Insulation Resistance testing is ineffective to detect impending inter-turn and inter-phase shorts. Power factor voltage and current (all three phases and individual phases) Efficiency: The efficiency can be calculated/measured at various different load points, including full load as well as various different supply frequencies, supply voltages, etc. Power factor (all three phases and individual phases) The power factor can be measured on all three phases individually and at various different load points, including full load as well as various different supply frequencies, supply voltages, etc. Tan Delta testing: This test is used on new and service -aged windings to determine insulation condition. Partial Discharge: This analysis method determines the insulation condition of high voltage (4 kV and higher) windings by statistically measuring the partial discharge activity of a winding, and displaying it superimposed on the main supply voltages. Stray Flux (or Flux) Analysis: This method of measuring the instantaneous magnetic flux in a point location in the airgap of synchronous rotating machine allows the detection of short-circuited turns in the rotor. It can also be performed on running machines where there is access to the field winding terminals (slip-ring excited rotors or rotors with telemetry). The test compares two identically generated pulsed voltage waveforms, when applied with opposite polarity to the terminals of synchronous machine rotors. Efficiency, power factor, current and speed at various load points.
