WHAT IS CSA Z463? Provides guidance on:  The application of safety management systems 1. CSA Z460 Control of Hazardous Energy 2. CSA Z462 Arc Flash Hazard  The selection of reference standards and maintenance procedures  The assessment of electrical equipment to verify correct function  Provide an increased level of safety for electrical workers 3

WHY HAS CSA Z463 BEEN CREATED?  To help address the ongoing concerns regarding the impact of maintenance neglect on worker’s safety  To define the difference between maintenance on equipment critical for worker safety versus those critical for production  CSA Z463 will complement CSA Z462 and CSA Z460 4

LACK OF MAINTENANCE Results in:  Higher risk to all workers  Loss of production  High repair costs  Loss of business  Loss of market share  Total loss is possible

WHY IS MAINTENANCE CRITICAL?  Unexpected failure while in service or during operation  Worker safety as protective equipment operating times can increase causing unexpected high arc flash levels  Extreme equipment damage and downtime 6

7 Maintaining speed of protective device operation reduces arc flash hazard levels Calculated: 5.7 Cal/cm 2 Actual: 94.9 Cal/cm 2 A safe situation becomes extremely dangerous in a very short period of time. A difference of milliseconds can be disastrous! MAINTAINING CALCULATED ARC FLASH HAZARD LEVELS.

Maintenance Statistics NETA Survey  23% of breakers do not follow their designed operating characteristics  10.5% of circuit breakers do not operate at all 8

MOTOR STARTER FAILURE  Failure of the switchgear was caused to a fault in the feeder system. The protective relay system was not operating.

TRANSFORMER WINDING  Multiple turn to turn faults caused by insulation decay due to highly acidic oil.

SWITCHGEAR FIRE  Failure of the switchgear was caused low insulation resistance of the main bus support insulators. The cause was the build up of corona.

SWITCHGEAR EXPLOSION  Result of water leaking in.

CABLE FAILURE  Corona buildup on stress cone terminations

CIRCUIT BREAKER FAILURE  The contacts of this breaker eventually failed as a result of high contact resistance.  The ensuing fire cause severe damage to the switchgear and a power failure to the plant.

 CSA Z463 will provide: Guidance and Measurement to Industry Government Stakeholders 15

MAINTENANCE STRATEGY  System limitations and needs  Life span Mean Time To Failure (MTTF)  Equipment is designed to operate for a defined number of cycles or operations, meaning planned obsolescence  The design life makes periodic maintenance necessary

STRATEGY CONSIDERATION  What are the functions and performance standards of the asset  How does it fail to fulfill the intended function  What are the causes of each functional failure  What is the effect of each functional failure  In what way does each functional failure affect operability  What can be done to predict each failure  What are the alternatives if suitable maintenance can not be performed
