Modern relay protection can be extremely complex or relatively simple, depending on the relay model and design engineer. It is possible to use some testing techniques from previous relay generations, but these techniques only test individual elements, which does not guarantee the relay is set correctly or will operate when required.
Most modern relay problems have nothing to do with the actual relay as supplied by the manufacturer. Today’s relay problems occur when the relay has been incorrectly connected to the power system or was set incorrectly by the design engineer. Unfortunately, these problems cannot be detected by traditional relay testing techniques that reprogram the relay in order to get the right test value for the test sheet. Traditional techniques don’t ask the right questions to find the problems that prevent the relay from operating.
Modern relay testers must apply several different skill sets to effectively test digital relays so that they can get the test results they need for their reports, and make sure the relay is properly applied. This class will provide the basic knowledge every modern relay tester should have including:
Anyone who wants to learn more about relay testing, but doesn’t know where to start; or an inexperienced relay tester who has been thrown to the wolves on projects and is tired of winging it.
Don’t have enough personnel to make it cost effective to bring our instructor to you? Contact us to see if we can minimize your costs by creating an open-registration, regional training class near your location.
Prospective students should have a basic understanding of the power system such as Watts, VARs, Ohm’s Law, etc.
Classes at your location range from $5,000 to $7,500 USD depending on the number of workstations required.
The Introduction to Modern Relay Protection Testing class is eligible for 24 NETA Continuing Technical Development Credits (CTDs). NETA Certified Technicians (Level III and Level IV) are required to earn a minimum of 48 CTDs every three years to maintain their certification. For more information about the CTD program and requirements, please contact the NETA office at [email protected] or 888-300-6382.
