In conjunction with:

Switchgear, like many other types of industrial equipment, is often unnoticed and neglected until it fails to function normally. The level to whichswitchgear is maintained in industry varies significantly.

● Maintenance levels at one extreme might involve ‘Condition Monitoring’ (Continuous Monitoring) of equipmentwith linear or rotatingtransducers.

● At the other end of the spectrum, maintenance might only involve doing Periodic Maintenance Tasks (PMT), Inspections or even MajorMaintenance Task (MOT).

● One can also run equipment until it breaks down or even self destructs.● The vast majority of appropriate switchgear maintenance programs will fall somewhere in between these extremes.

Overview

Hevilex cc has identified these issues, not just as white coat specialist trainers, but during hands-on circuit breakerbreakdowns & repairs, mechanism/pole malfunction problem solving, different maintenance tasks, writing ofmaintenance manuals and the writing of ‘specific specifications/requirements’ for purchasing of new circuit breakers.

This workshop will highlight all the challenges and issues encountered when it comes to the maintenance of HV and MV Switchgear.

This course will provide you with the opportunity to walk away with the skills to most importantly understand the theory of how a circuit breakermechanism & interrupter chamber works, ensure that the correct maintenance activities are carried out effectively, implement failure investigations,identify ways in which to do the maintenance cost effectively and not end up ‘over or under’ maintaining the equipment.

All training courses offered by Peganix have CPD points allocated to them and we are confident that the benefits of attending are obvious and reflectthe quality associated with accreditation. This course has been validated by the SAIEE as per ECSA policy under validation no. SAIEE-1598-V for 2

CPD credits.

Upcomig Workshop

Electrical Power, Instruments & Control Systems

2 CPD | 14th - 15th September 2017, Johannesburg. RSAThis workshop is designed to update participants with the latest development of Circuit Breakers and to

present some of the more common and updated aspects of low, medium and high voltage switchgearmaintenance. It must be understood that there is an incredible variety of equipment used on low, mediumand high voltage switchgear today. Switchgears play an important role in the distribution and control of

electrical power in manufacturing or power plant and in a utility distribution system. Negligentmaintenance practices can lead to power system inefficiency and loss of system reliability.
