This course focuses on what to do, when to do it and how to interpret the results from testing and maintenance. Systems Engineering has registered Professional Engineers experienced with the design, fabrication, programming, and testing of substation protection panels. We are a leading company that designs, manufactures and market a range of electronic products and solutions for electrical testing, mainly in protection relay field and in general, tests and measurement equipment related to the commissioning and maintenance in substations, power plants and energy systems. Secondary and primary testing; The SVERKER 900 relay and substation test system is the engineer's ultimate testbox that addresses the increasing need for three-phase testing capability in electrical distribution substations, renewable power generation stations and industrial applications. *High end multi-phase relay test sets, DRTS series from ISA, available in 4 configurations (6I-6V, 6I-4V, 3I-4V and 3I-3V) and can provide up to 430VA per current output for each of 6I outputs (see input power supply spec) and all 6I at up to 32Amps per channel. Substation, Switchgear and Equipment Maintenance and Testing. Analog or digital filtering techniques are applied to obtain the fundamental components of current. Much like bridges on the highway, they are very critical and the weakest link. that are self-powered via current sensors or with auxiliary supply protection relays (VIP410 relays). Powerhouse, Substation, and Relay Electrical and Electronics Repairers. 1 Connect the voltage injector’s output as shown in fig. Engineering / Design service for Power plants, Substation Engineering / Design service for Low Voltage System, MV, HV Voltage System Annual Maintains Services (AMC). CANUS Corporation provides experienced personnel to test either electro-mechanical protective relays, solid state protective relays or microprocessor based relays. Substation Commissioning • Relay Testing – Testing the relay is managed in different ways, but the goal is to prove the relay settings, relay logic, and relay functions are all working to “as set” settings – Element testing can be accomplished via manual or automatic testing. Key Considerations for Utility Substation Testing. For PG&E to provide the Load Entity or Transmission Entity with timely service it is important that all time requirements be met. e PTR , CTs ,PTs ,LA 2- Testing of all electrical equipment i. Visit PayScale to research substation technician hourly pay by city, experience, skill, employer and more. Testing & Commissioning of 22 KV Substation at RAILWAYS. Our reputation has been built on providing testing services that ensure entirely functional equipment and precise as-built drawings and documentation of the completed project. Single-phase AC/DC Relay Test Set. Product Description. Introduction to Relays. The ARFD-200 is a rugged test set suitable for testing a variety of protection relays operated in both indoor and outdoor environments. We Offer Full Service NETA Certified High Voltage Testing For Power Transformers, Protective Relays, Switchgears, SF6 Breakers and All Other Hi Voltage Equipment. This permits using a test set to check the relay calibration. Commissioning tools compliant for IEC 61850 environments, high burden electromechanical relays, GPS and IRIG-B can be completed by all-in-one test sets. CANUS tests using state of the art relay test sets including Omicron, Doble and Manta. Schedule and supervise the construction and testing of special devices and the implementation of unique monitoring or control systems. Secondary and primary testing; The SVERKER 900 Relay and Substation Test System is the engineer's ultimate toolbox that addresses the increasing need for three-phase testing capability in electrical distribution substations, renewable power generation stations and industrial applications. 00 SCOPE: 1.
