Description
Performs electrical tests and repairs concerned with maintenance and performance evaluation of in-service relays to prevent and Remedy abnormal behavior or failure of transmission and distribution lines and equipment: Connects test apparatus to troubled circuit.
Analyzes test results and interprets electrical diagrams to locate defective relay. Opens and closes Switches to isolate defective relay and makes adjustments or removes relay for repair. Tests circuit and equipment to evaluate such factors as insulation quality, which affect function of relays. Analyzes test data to determine performance characteristics of relays and effect of system modifications on relay performance. Prepares reports of work performed. Will be working with SEL S; ABB DPU 2000R Relays (Below for standards)
On SEL 351 or SEL 351S relays, using AcSELerator software to download the installed settings to techs laptop before any testing is begun. When testing is completed the settings will be compared to the original settings that were saved to techs laptop. The tech shall already have the most recent version of the program installed on his laptop when he arrives, and be proficient in using the software and testing SEL 351 and 351S relays.
On ABB DPU 2000R relays, the same as above except using Win ECP, which is ABBs relay interface program. The tech shall already have the most recent version of the program installed on his laptop when he arrives, and be proficient in using the software and testing ABB DPU 2000R relays.
All testing shall be in accordance with the NETA ATS-2009, Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems, Paragraph 7.9.2 testing procedures.
