Subsurface Vault Feeder Monitoring—Use the SCT in conjunction with an SEL relay, like the SEL-787 Transformer Protection Relay, and an SEL-3060 Ethernet Radio to wirelessly send feeder data to a supervisory control and data acquisition (SCADA) system or distribution management system (DMS) or for engineering support. Build an economical system to monitor loads, detect overload conditions, and capture pre- and postevent data.
Load Current and Overcurrent Sensing—Apply SCTs to serve as an input for source transfer relays. Use SCTs to distinguish fault current from load current to prevent switching into a fault.
Wet Environment Submetering—Use SCTs to submeter equipment within wet environments, including water treatment plants, pulp and paper mills, and other environments subject to water and extreme humidity.
