A power system study is an analysis of an electrical power system to evaluate its performance and ensure its safe and reliable operation. It involves using computer simulations and specialized equipment to study the behavior of the power system under different conditions such as varying loads, faults, and switching operations.  Our team of experienced engineers can perform a variety of power systems studies, including:

• Short-circuit studies: These studies determine the maximum fault current that can flow on a system.
• Arc flash studies: These studies determine the potential for arc flash hazards and the appropriate protective measures.
• Coordination studies: These studies ensure that protective devices, such as circuit breakers and fuses, are properly coordinated to protect equipment and personnel from electrical hazards.
• Fault current studies: These studies determine the maximum fault current that can flow on a system. This information is important for the design and sizing of protective devices, such as circuit breakers and transformers.

A comprehensive power system study can help identify potential problems, optimize system performance, and prevent costly downtime.

We can also provide you with recommendations for improving the safety, reliability, and efficiency of your power system. With the ever-increasing complexity of modern power systems, it's more important than ever to have a thorough understanding of the behavior of the system under normal and abnormal conditions.

 

FAQ:

Q:  Who is doing these power system studies?

A:  We collaborate with a network of engineers across several states to complete and stamp your power system study.  

Q:  How long does the power system study take?

A:  Normally, we get them back in approximately two weeks after we gather all the data needed to finish the study.  Depending on their complexity, smaller projects can often be finished in a shorter period of time. 

Q:  What all do you need to complete a study?

A:  For initial quoting we will need the Latest/current one-line diagram and possibly details for the power distribution equipment used for the project.  We will send out a request for information as soon as we have an order, this will included the following items:  Latest/current one-line diagram, project specification for the study, all cable lengths for feeds shown on the one-line complete with type, size, number of runs per circuit and conduit type for each feed, a current bill of material (and possibly drawings) for the power distribution equipment used for the project, and nameplate data from the utility transformer feeding the building.  If the study is for a new addition or change to an existing building, we may request the original study provided if it is available.

Q:  Why would I work with I-Pro Martin Services & Solutions on a study instead of a traditional gear manufacturer team?  

A:  Our engineer teams are faster, easier to work with, and will get you the information and reports you need to satisfy your project requirements.

 

Arc Flash Studies

Arc flash is a serious hazard that can cause serious injury or death to electrical workers. Our team of experienced engineers can perform arc flash studies to determine the potential for arc flash hazards and the appropriate protective measures. We can provide you with a detailed report that includes:

• The estimated incident energy (cal/cm²)
• The arc flash boundary
• The required personal protective equipment (PPE)
• Recommended safe work practices

We can also help you implement the recommendations of our arc flash study to protect your workers from arc flash hazards.

An arc flash study is a comprehensive evaluation of electrical systems to determine the potential risk of arc flash hazards, which can occur when electrical energy is released through the air in an uncontrolled manner.

 

Coordination Studies

Coordination studies are essential for ensuring the safe and reliable operation of your electrical system. They help you ensure that your protective devices, such as circuit breakers and fuses, are properly coordinated to protect your equipment and personnel from electrical hazards. Our coordination studies are conducted by experienced engineers who use the latest software and methods. We can provide you with a detailed report that includes recommendations for protective device settings.

A coordination study is an analysis of the protective devices in an electrical power system, such as fuses, circuit breakers, and relays, to ensure they work together properly in the event of an electrical fault.

In an electrical power system, protective devices are used to detect and isolate faults, or abnormal conditions that can damage equipment or create safety hazards. When a fault occurs, the protective devices must work together in a coordinated manner to isolate the faulted equipment and minimize the impact on the rest of the power system.

 

Selective Coordination

Selective coordination is a type of coordination study that ensures that protective devices only trip the circuit that is experiencing the fault. This helps to prevent nuisance tripping and maintain the reliability of your electrical system. Our selective coordination studies are conducted by experienced engineers who use the latest software and methods. We can provide you with a detailed report that includes recommendations for protective device settings.

Selective coordination is a type of protective device coordination that ensures that only the protective device closest to the fault condition operates to isolate the fault, while allowing all other devices further away to remain in service.

In an electrical power system, protective devices such as circuit breakers, fuses, and relays are installed at various points along the power distribution path to detect and isolate faults. However, if these devices are not coordinated properly, a fault in one part of the system can cause multiple devices to trip, leading to an unnecessary and potentially widespread power outage.

Selective coordination prevents this by ensuring that the protective device closest to the fault operates first, while all other devices further away remain in service. This allows power to continue flowing to unaffected parts of the system and minimizes the impact of the fault.

 

Fault Current Studies

Fault current studies are used to determine the maximum fault current that can flow on a power system. This information is important for the design and sizing of protective devices, such as circuit breakers and transformers. Our fault current studies are conducted by experienced engineers who use the latest software and methods. We can provide you with a detailed report that includes the maximum fault current for each circuit in your system.

A fault current study is an analysis of an electrical power system to determine the level of current that would flow through the system in the event of an electrical fault.

In an electrical power system, faults can occur when there is a break or short circuit in the wiring or equipment, which can lead to high levels of current flowing through the system. A fault current study helps to determine the maximum amount of current that could flow in such an event, which is important for selecting the appropriate protective devices and equipment.
