Power system protection software applications

Network protection is key to mitigate the risks in an interconnected power system and enhance the reliability of the power supply while contributing to the resilience of the system itself. Proper protection equipment modeling is an essential task for the power engineer. 

Risk mitigation
Evaluate & design protection schemes
Arc hazard level evaluation
Safeguard personnel from arc flash hazards
Reliability assessment
Reduce power outages & improve SAIFI & SAIDI

Core features

  • Protection analyses covering device coordination, loading, reach, minimum fault protection and sequence of operation
  • Overcurrent protection with time-current curve plots from a curve library hosting more than 100,000 curves from manufacturers
  • Arc flash hazard studies compliant with industry standards to calculate incident energy level
  • Reduction in protective reach, sympathetic tripping and minimum fault protection verification for DER hosting and impact studies
  • One-line diagram color-coding schemes to pinpoint the protection issue at hand

Validate network protection scheme

Proper selection and sizing of protective devices are key to reducing the impact caused by network faults and minimizing equipment failures.

Improving risk management

Risk management and prevention have always been important aspects of safety programs within the electric industry. Proper assessment of arc flash risk level according to industry-recognized standards is necessary to ensure a safer work environment and minimize operational downtime.

DER impact on network protection

The installation of distributed energy resources can cause two-way flows and have an impact on traditional protection schemes. Identify potential sympathetic tripping, reduction of protective reach and minimum fault clearance issues caused by DER on the system.

Protective device analysis

Arc flash hazards analysis

Properly assess the arc flash risk level to ensure a safer work environment by computing the necessary parameters required to determine risk level and adopt adequate safety procedures. This includes a new method that factors in backup protection, multiple contribution and duration.

Distance protection analysis

Analyze the operation of distance protection relays under normal and fault conditions. Helps in the design and verification of protection schemes and to address different coordination issues in any power system network

Reliability assessment


Reliability assessment has become more important for utility planners in recent years. Improved service reliability might be motivated by government regulation or by market competition, but providing superior service at an attractive price is in the interest of both the utility and the customer.

Protective device coordination

Engineers are often called upon to visualize the protection of their networks quickly and easily.
