Pharmaceuticals are driven by innovation and efficiency. Sensitive loads in the process are highly susceptible to power quality issues.
Pharma processes use variable frequency drives and electronic controls to ensure product quality. Cleanroom control and compressor drives are sensitive to voltage sags.
These are some common challenges you will encounter in your pharmaceutical plant when you have power quality issues:
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.
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 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.
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.
The Omniverter approach is to understand your particular issue via data analysis prior to offering a product solution. The following solutions were used individually or in combination in various pharmaceutical plants:
Benefits derived from Omniverter solutions:
There are many types of loads used in a pharma manufacturing plant, each with its own unique characteristics. One common denominator is that they all need continuous steady voltage supply to operate. Most unplanned stoppages are due to voltage sags (weather-related) or transient overvoltage conditions during capacitor switching upstream in the network.
Omniverter Active Voltage Conditioner(AVC) continuously regulates the voltage, balances all three phases, and compensates for three-phase and single-phase sags in the network.
Omniverter Resonance Elimination Harmonic Filter (REHF), can be configured to correct the effects of capacitor switching transients.
