  • UltraVolt HVPS Output-Current Monitor
    UltraVolt's high-voltage power supplies (HVPSs) have an output-current monitor (Iout Monitor), which allows the total output current of the HV multiplier to be monitored. Note, since the sense circuit is in the return path to the transformer, the current-monitor signal has a sign opposite
  • Ergon Energy Optimizes its Asset Ultilization with Online Transformer Monitoring
    Energy is. increasing the use of online monitoring of their assets. Vaisala's MMT338 transmitters monitor online moisture of transformer oil. helping in maintenance planning and daily grid operations.
  • Monitoring Higher Voltages
    Some building electrical systems just will not cooperate when it comes time to monitor power. You search and search and cannot find a point to monitor power on the low voltage side of the transformer (below 600 volts). Now you must face the fact that only the high voltage side can be used for power
  • Flexible Solutions for Isolated AC Line Monitoring
    Isolated ADCs are essential for applications where the power drawn from the ac mains must be monitored. The most common solution for these applications today uses a current transformer coupled with discrete components and a data converter - a bulky approach that drives up the size and complexity
  • Factors in the Selection of MIL-STD-1553 Couplers, Connectors and Harnesses
    and straightforward, do not address variations from transformer to transformer within allowable parameters. Under normal conditions and usage most couplers are satisfactory and interchangeable, even with small variations in fault isolation resistor values, as long as they have the same nominal turns ratio. Some
  • Why Neutral Grounding Resistors Need Monitoring (.pdf)
    A resistance-grounded power system has a critical element that is often ignored-the neutral-grounding resistor. A resistance-grounded power system should have it's neutral-grounding resistor continuously monitored. During a single-phase-to-ground fault, current flows from the transformer
  • Using Current-Limiting Fuses to Increase SCCR of Industrial Control Panels (.pdf)
    A resistance-grounded power system has a critical element that is often ignored-the neutral-grounding resistor. A resistance-grounded power system should have it's neutral-grounding resistor continuously monitored. During a single-phase-to-ground fault, current flows from the transformer
