OVERHEAD TRANSFORMER METER Quick two unit installation Self powered User initiates dowload via radio Communicates with secure radio protocols SINGLE PHASE TRANSFORMER METER The TMS provides utility groups with precise information to quickly identify inefficient transformer loading without the requirement of advance metering infrastructure. The Transformer Meter System easily installs onto the secondary of a pole mounted Transformer. The open core CT allows installation while the transformer is energized. The meters employ an insulation piercing connector that securely attaches the sensor to the conductor. This voltage connection supplies the voltage measurement and power to operate the TMS. The innovative design allows the user to quickly install at any point between the transformer and the meter. This low-profile unit is discreet and difficult to visually detect from distance. Approximately 330 days of interval data stores on the system. Using secure radio protocol, this stored data is downloaded while the meters are still deployed on the line. The following parameters are recorded: - Accumulated Kilowatt Hours - Average Volts - Average Amps - Interval Kilowatt Hours The secure point-to-point radio communication is a standards based, non-licensed wireless network solution that supports low power consumption, security, and reliability. The radio communicates to a USB radio dongle on the user's laptop. SensorLink's Steelhead Software is a customized user interface for the setup, download, and review of the recorded data. Data may also be saved to a .csv file for uploading and review in other data management programs. Ampstik WJ, Padmount Conductor Ampstik XT, Overhead Conductor
