Critical power: The lifeline for hospitals & healthcare

MRI scanning electrical power problems

The consequences of sags can be severe, failure of critical equipment, data loss, or shutdown of computer controls in hospitals.

Challenges our Customers Experience before engaging Omniverter

Power Quality investigation at MRI
Electronic board failure due to high harmonic currents

Electronic equipment in hospitals is prone to failure when electrical power quality anomalies occur. These are some of the typical issues Omniverter identified during investigations:

  • Power supply failures of equipment.
  • Nuisance stopping of electronic equipment.
  • Electrical breaker tripping and power outages.
  • Reduced reliability of scanning equipment.
  • Premature failure of electronic equipment.

Common Power Quality Issues Causing these Problems

Voltage Sag

Voltage Sag/Dips

Voltage sags are the primary cause of unplanned production stoppages in industry. Causes include electrical network faults due to weather, animals across terminals, traffic accidents, load switching upstream, startup of large loads or transformer energization.

Voltage Transiets

Voltage Transients

A sudden change from the nominal voltage or current may be caused by faults in the network, switching of large loads, load shedding, or switching of capacitor banks upstream in the utility network. Voltage surges also occur but may be less severe.

Power Interruption

Momentary Power Interruptions

Momentary power loss is complete loss of voltage on one or more phase conductors between 0.5 cycles and 3 seconds.  The most common forms of power failure are due to utility protection systems, e.g. recloser operations, switching, breaker tripping and equipment failures.

Harmonic Distortion

Current & Voltage Harmonic Distortion

The use of non-linear loads is the main cause of harmonic distortion. The injection of harmonic currents results in voltage distortion which may cause electronic equipment failure, increased heat in drives and transformers, unwanted tripping, malfunction of sensitive equipment and controls and failure of imaging and scanning equipment.
