Clean electricity.
WHAT POWER PROBLEMS OCCUR
Surges Dips and brownouts Complete interruptions Frequency variation Harmonic distortion
WHAT DAMAGE THEY CAUSE
Immediate failure, in severe cases Gradual degradation, more commonly
WHY THAT SECOND ONE MATTERS
Equipment fails earlier than expected, and the cause is never identified.
WHAT PROTECTS AGAINST IT
Uninterruptible supplies conditioning the power Surge protection at entry Proper earthing
WHY EARTHING MATTERS
Poor earthing causes intermittent faults that are extremely difficult to diagnose, and is a safety hazard.
WHAT TO VERIFY
That earthing has been tested and documented.
WHAT MATTERS PARTICULARLY HERE
Grid supply quality varies, and fluctuation is routine rather than exceptional.
WHAT THAT MEANS
Conditioning is not optional protection but a normal operating requirement.
WHAT TO MONITOR
Supply quality, so problems are visible.
WHAT TO ASK A FACILITY
What conditioning exists, and what supply events have occurred.
WHAT TO CHECK IN YOUR OWN PREMISES
The same principles, at smaller scale.
