When PowerSource conducts your specialized power studies, you receive the highest-quality data, along with expert guidance that helps you make the most of it. PowerSource studies include:

One-Line Diagram Creation or Revision

A one-line diagram uses simplified notation to give a comprehensive overview of your power system.

• Simplifies electrical system troubleshooting and new construction

• Provides the most up-to-date information for performing accurate power system studies

Protective Device Coordination Study

This study determines optimum settings for circuit breakers and relays and determines ampacities for any fuses in the system.

• Increases equipment protection

• Ensures protective devices will trip in sequence.

• Increases facility reliability by limiting the effects of a fault or overload to a limited area of the distribution system.

 

• Short-Circuit Study

This study calculates short-circuit fault current levels and compares them to your equipment short-circuit interrupt/withstand ratings to identify potential problems.

• Identifies underrated equipment before extensive damage can occur

• Increases reliability, equipment protection and safety

• Provides accurate fault current calculations at each location in the system to properly rated equipment can be specified.

 

• Load Flow Study

This study calculates Kilowatts (KW), Kilovars (KVAR), Power Factor (PF) and voltage drops and determines how the system will operate in normal and emergency conditions.

• Reduces your electric bill by determining the location and size of power factor correction capacitors

• Demonstrates how the electrical system will perform during normal and emergency conditions

• Determines the proper transformer tap settings to ensure correct voltage during full load and no-load conditions

• Identifies under-utilized equipment that can accommodate future load growth

• Determines the optimum operating configuration

 

• Motor Starting

This study creates a model that simulates motors starting on your distribution system.

• Reduces voltage drop or flicker problems

• Increases facility reliability

 

• Harmonic Study

This study identifies monitors and measures harmonics generated by non-linear equipment.

• Identifies the source of harmonics (internal or external to your facility)

• Evaluates the impact of harmonic sources on the system

• Evaluates compliance with IEEE 519

• Determines proper size and placement of capacitors and/or filters when harmonic sources are present

 

• Power Factor Study

This study determines the size and location of capacitors to improve power system efficiency and eliminate penalty charges.

• Improves voltage profile

• Ensures proper sizing and placing of capacitors

• Verifies that there will be no abnormal interaction between harmonic sources and the capacitors

 

• Transient Analysis Study

This study locates the cause of damaging transients and identifies solutions to minimize or eliminate them.

• Increases equipment protection and reliability

• Ensures protective devices and switching equipment operate correctly
