Founded in 1945, the Association of Electrical and Mechanical Trades is an International Association representing companies in the electrical and mechanical service and repair industry.

This is the last time I will be introducing an issue of Renew magazine as President of the AEMT. At our Association AGM in June, with my fixed term of office at a close, I passed the baton over to James Stevens of Preformed Windings, as he takes on the President's role for the next two years.

I have thoroughly enjoyed my time as President and the opportunity to contribute to shaping the ongoing direction of our Association. A key area of focus for me during my time in office has been the people within our membership. And by that, I mean all the people working within our member organisation. I believe in collaboration and the power of sharing knowledge and experience, and I hope as I leave my position, the Association has grown in those vital areas and our membership has benefited as a result.

I want to thank all the council members for their support over the last couple of years and hope that as we move forward, we continue to attract and secure such enthusiastic and dedicated people within the organisation.

I would like to also thank my predecessor, David Hawley, for all his hard work and support in the run-up to my taking over and as past President during my tenure.

I would, however, particularly like to thank the AEMT team, Thomas, Karl, Rebecca and Lesley, for all their incredible work in the day-to-day running of the Association.

I am confident that the AEMT will remain in good hands as James Stevens takes over the Presidency, and I am excited to see what the future holds for the Association and, of course, its members. We must never forget those members carry out incredibly important work each and every day, and it is a privilege for the Association to support them.

PD and Tan delta testing, PD online monitoring

Partial Discharge and Tan delta testing is together with Static testing complementing the standard FAT and on site testing procedure of the insulation status for critical HV motors and generators.

The ICMflex system can perform PD and Tan delta testing in one simultaneous test sequence with one common test report. It is a compact and portable all in one unit suitable for on site, as well as workshop testing. Portable AC Hipot solutions are available too.

The ICMmonitor system is an approved solution for online Partial Discharge monitoring on HV rotating machines and it can come as a portable unit for temporary monitoring/ spot testing, or as a permanently installed monitoring cabinet with remote access and alarming.

Megger Baker Electric Motor Analyzers

The Baker Instruments family of electric motor analyzers provides a comprehensive suite of tests which characterize the health of your motors and generators. These testers are valuable in industrial settings for predictive maintenance, and in motor repair/rewind shops for troubleshooting and QA.
