The SCADA Technician Apprentice under direct supervision will assist to design, install, maintain and document all Remote Terminal Units (RTU), metering and communication equipment required for the control and data acquisition from various Member Cooperative’s end devices to the System Control and Data Acquisition (SCADA) master stations. In a safe and efficient manner as prescribed by GSEC or member coops safety guidelines and policies.
Works closely under supervision to develop these skillsets listed below.
Equipment Design, Installation, and Maintenance:
Reviews maintenance and outage reports periodically for problem identification and /or trends. Takes appropriate corrective action. Diagnose and repair communications equipment used to poll meters for real time data.
Design, install, order, configure, program, troubleshoot, maintain and repair the following:
Spread Spectrum Radio network equipment and associated antennas and feed lines
Remote Terminal Units (RTU), including latest firmware upgrades. (Various models)
Electric Revenue Meters (MTR) including latest firmware upgrades. (Various models)
Leased Telco lines including modems, DSU/CSU and associated wiring
Terminal servers, routers, VPN firewalls, switches, including firmware upgrades
Operate and maintain a variety of test equipment including a multi-meter, antenna analyzer, protocol analyzer and Optical Time Domain Reflectometer (OTDR)
Install, test and maintain a substation fiber network for Member Cooperatives
Develop and maintain detailed documentation on each site, such as:
Schematics and wiring diagrams
Member Coop maps and system configuration drawings
Equipment layout and site inventory
RTU & IED DNP point mapping
Establish and maintain a master library for database files and programs for RTUs and meters
Provide technical assistance and guidance to Member Cooperative technical staff, as needed
Follow safety rules and regulations of OSHA and the Cooperative and observe safe working habits.
Attending four-member cooperative safety training a year
Must be able to work safely with low voltages in electrical substation environments.
Complexity of Problems
Basic troubleshooting skills will apply to most all situations.
The SCADA Tech must be able to identify the problem and then safely search for the cause. For instance, a common problem found is a blown fuse. Simply replacing the fuse with a larger amperage fuse may cause further damage to the equipment or flashover to personnel.
Safety procedures must be followed at all times, especially when working alone.
Problems that are not so easily solved, such as RF interference and intermittent outages for no apparent reason. Some problems are beyond our control, such as lightning surges, storm damage and other equipment failures.
Some problems will require a coordinated effort among various Member Cooperatives, Power Suppliers, and telephone companies in order to perform certain testing and commissioning.
Education, Knowledge, and Experience Required
Associates degree from an accredited engineering or technical school in electronics or telecommunications or an equivalent combination of experience and/or education.
1 to 3 years of experience in the installation, repair and maintenance of computer, telecommunications, or electronic equipment associated with electrical power utility and substation equipment.
Proficiency with electronics as it relates to trouble shooting and repair of radio systems, SCADA RTUs, electric revenue meters, serial servers, and ethernet switches
Possess the ability to analyze and solve problems encountered in the field. Proficiency with problem isolation and ability to reduce system problems to discrete components.
Must be able to lift 50 lbs.
Must be able to work independently with minimal supervision.
Have a valid state driver’s license.
