This one-day course is designed for substation engineers for better understanding the construction, inspection, and maintenance requirements for substation batteries. Engineers directly involved in maintaining substations and LV/MV/HV DC auxiliary switchgears or those requiring an understanding of the various tests and or diagnostics and analyzing test results will gain a better understanding of best maintenance practices as required by industry accepted standards.
Training program is based on: (1) Canadian Standards Association: CSA Z463- Standard for Maintenance of Electrical Systems; (2) Canadian Standards Association: CSA Z462- Standard for Electrical Safety; (3) National Electrical Testing Association (NETA): ANSI/NETA 2019 Standard for Maintenance Testing Specifications and (4) Professional Electrical Apparatus Recyclers League: Reconditioning Standards for Electrical Equipment.
Each student receives comprehensive digital version of reference material including maintenance frequencies, PEARL test standards and test forms.
After the training, the successful candidate will be able to:
- Verify that batteries are adequately located.
- Verify that battery area ventilation system is operable.
- Verify existence of suitable eyewash equipment.
- Compare equipment nameplate data with drawings and specifications.
- Inspect physical and mechanical condition.
- Verify adequacy of battery support racks, mounting, anchorage, alignment, grounding and clearances.
- Verify electrolyte level. Measure electrolyte specific gravity and temperature levels.
- Verify presence of flame arresters.
- Verify the units are clean.
- Inspect spill containment installation.
- Verify application of an oxide inhibitor on battery terminal connections.
- and many more…
Who should attend:
This training is recommended for: Substation engineers and technicians, electrical test technicians and commissioning engineers, protection and control engineers, managers and substation supervisors.
Please note that his training can be modified to suit your specific needs. We will be happy to conduct a needs analysis with you to determine your specific requirements. It can be conducted either on-site or off-site.
