— CASE STUDY Hi-Tech ® fuse PT protection Industry: Electric utility Challenge: Protection for potential transformer Product: Hi-Tech Trans-Guard TM FX fuses Abstract Today’s utilities benefit greatly from advances in supervisory control and data acquisition (SCADA) that allow system information and equipment to be monitored remotely. Historically, overhead capacitor banks have not been well monitored and may only be subject to once-a-year, ride-by inspection to ensure that they are in service and working properly. However, SCADA has provided an alternative. When applying SCADA to overhead capacitors, a potential transformer (PT) is used to power the electronics. A large utility deployed SCADA and connected to the source side of a capacitor bank for power. Once deploy
