Corporate Building fixes UPS and Elevator problem
Intelligent Building eliminates UPS and Elevator failure
UPS Problem | How to troubleshoot the extraordinary equipment failure, electrical fire and occupants’ safety issue in a building? Read this case study how building harmonic filter fixes light flicker & UPS tripping with grid voltage fluctuation. How harmonic causes electronic card failure and creates trouble with elevator operation. The quality of the incoming power supply from the utility grid carries crucial performance parameters for the building equipment.
Why UPS fails to mitigate incoming voltage fluctuation
Though it’s not at the hand of building engineers, they have engineering tool to condition the incoming power quality. UPS powers critical building loads, namely work station computers, corporate data center servers and emergency lighting. Many wonders why sensitive equipment powered by UPS fails on voltage fluctuation? Why emergency lighting at the UPS output supply flickers on grid voltage dip? UPS is not a power conditioner but more of a convenience. It can only condition the steady-state voltage profile. UPS can’t mitigate momentary voltage transient and power surge, which typically lasts in milliseconds,and passes those to output supply in the form of DC ripples.
How to assess Electrical Fire Risk and its prevention measures
When it comes to electrical fire risk assessment of a building, there arise six questions which determine the correlational root cause analysis of the fire incident.
1. How did the electrical fire seem to have ignited?
2. Where, in the building, the fire started first?
3. Did the fire spread too quickly, if yes, why so?
4. Did the fire start from multiple locations in the facility?
5. Did the fire originating spot(s) have high energy intensity load(s)?
6. Is this a sophisticated, intelligent building with modern gadgets or a conventional building?
Once we have sufficient answers and clarity on the first two questions, the likely reason for the fire is simple, either worn out installation or negligence. The possible causes could include worn out or undersized electrical wiring, faulty electrical receptacles switches or outlets, weary appliances, worn-out light fittings or unrestricted use and haphazardly placed extension cords or loosely connected gadgets.
If, however, the questions are beyond the first two, the reasons could be varied, and only an experienced electrical engineer can get to the bottom of the problem and troubleshoot its further recurrence. Nonetheless, attributing electrical short circuit as a cause for every building fire is an invention of the press, television and entertainment media, social media and newspapers. The probability of an electrical short circuit fire is pretty low, anyway. High neutral current is a major-reason for igniting an electrical fire, anywhere in a building, at multiple locations along with the building’s electrical power system. It’s a technological fire incident. The modern and high tech buildings are not only susceptible to it but their sophisticated electrical and electronic gadgets and LED lights generate triplen harmonics which triple at neutral and create a high neutral current. Triplen harmonic filter by removing the neutral current from the building’s electrical power system, greatly-eliminates the electrical fire risk.
