Hospitals and Healthcare

Improve the reliability of medical equipment in hospitals

No healthcare facility can afford medical equipment failures, whether it is due to momentary power outages or voltage sags. The consequences of sags can be severe, failure of critical equipment, data loss, or shutdown of computer controls.

Challenges our Customers Experience before engaging Omniverter

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 realibility of scanning equipment.
  • Premature failure of electronic equipment.

Common Power Quality Issues Causing these Problems

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 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.

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.

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.

Most Frequently Asked Question

What are possible causes and consequences of high harmonic distortion in my hospital?

Harmonics are the unwanted higher frequencies that are superimposed on the fundamental waveform. Harmonics being a current source flows in the opposite direction of normal power flow. This creates a voltage distorted waveform. Possible causes are non-linear loads like, rectifiers, VFDs, switching power supplies, and computers.

Consequences of high voltage distortion include overheating of transformers and neutral conductors, capacitor failures in electronic equipment, and induced background noise in sensors and imaging equipment (which results in inaccurate readings).
