Power System Surveys can range from very basic to quite in-depth and widespread.  Often, basic load measurements are required in order to understand current capacity requirements as compared to future needs.  When power disturbances are suspected, sophisticated "multi-node" analysis is usually required.

As changes in your power distribution system occur, they need to be periodically evaluated.  Loads change and new technology is applied throughout your facility.  The impact of these changes and the need for on-site power monitoring may be indicated in numerous ways:

• known or suspected power quality problems
• unexplained operation of overcurrent devices or "nuisance tripping"
• overheating of overcurrent devices and conductors
• changing energy costs
• load changes requiring evaluation

Powerserve Inc. can perform the necessary on-site monitoring services to feedback field data to the engineering group of your choice for further analysis.  Or, we can provide the engineering service as part of a total package solution.

• energy bill - power factor penalties
• VFDs tripping off-line on overvoltage
• mis-operation of telecommunications, automation, IT systems
• motors overheating or failing prematurely
• random circuit breaker tripping or fuse blowing
• overheating, humming and vibration of electrical equipment
• poor voltage regulation
• meter reading errors
• poor power factor
• failures or fuse blowing in existing power factor correction capacitors
• electrical system is operating at full capacity and more is needed
• high voltage spikes and surges
• power outages and interruptions

Several typical engineering services can be combined with on-site power monitoring to arrive at an overall solution:

• electrical drawing updates / creation: one-line diagrams, etc.
• harmonic and power factor study
• short circuit analysis
• protective device coordination study
• load flow study
• grounding study
• arc flash analysis and equipment labeling
