Engineering Services

McMahon can provide technical support for any electrical issues. We utilise in-house or rental equipment to assist in identifying power system issues and will provide practical recommendations for appropriate solutions. We can provide an audit of electrical installations and review compliance with the latest engineering standards.

McMahon engineers are conversant with issues such as supply harmonics, their cause, their effect and how their impact can be minimized.

We have in-house CAD skills including 3D modelling.

Project Management

To ensure smooth running of projects, we have developed management skills from field supervision to full project management level. The management team provides and schedules the necessary resources as required by project demand.

Total electrical project supervision and plant start up is taken on as a direct responsibility by our team should it be required by the Client.

We can supply the personnel that are required for installation supervision (resident Engineer) and for all plant commissioning from high voltage switchgear, transformers, motor control centers to programmable logic controllers and instrumentation.
