PPS has the experience and expertise needed to provide a variety of electrical protective relaying services. These include plant electrical system protection and device coordination, main generator protection, exciter protection and utility interface relaying for both AC and DC distribution systems. PPS can perform design and setting development that was historically provided by the electrical utility to these facilities but is no longer available due to deregulation. Services include modeling the distribution system, engineering analysis to develop settings, preparation of relaying programming to be uploaded to relays and third party reviews of relay and protection.
