Power System Protection & Analysis

PPE engineers are experts in power system protection from generation through transmission and distribution.  Our years of utility system protection experience, teaching, and IEEE participation give us the experience base from which to help our customers with practical solutions.  We can help your organization with relay setting calculations as well as teaching/mentoring newer protection engineers.  We can help evaluate your existing protection to satisfy NERC requirements and meet or exceed industry standards.   Using available oscillographic data from DFRs and digital relays we can analyze system events to provide details of operations leading to improvements in protection and coordination and finding incipient problems with equipment - all leading to an improvement in system reliability.  We are frequently called upon to provide independent, expert 3rd party engineering review of protection systems or root cause analysis of misoperations.

Power System Studies

Our primary expertise is protection and analysis but we can perform other system studies as well including load flow, voltage studies and transient analysis such as TRV studies for breaker applications and equipment specification studies.

Power system protection and analysis at all levels of generation, transmission, and distribution.

Third party expert engineering review of existing protection including those required to meet NERC requirements (PRC).
