11Kv and 33Kv Transformer Metering Unit Having CTR : 50-100-200 / 1 Amp.

A transformer metering unit with CTR (Current Transformer Ratio) of 50-100-200 / 1 Amp is a device used to measure electrical parameters (current, voltage, power, and energy) in high-voltage systems, utilizing current transformers (CTs) to step down high currents to a standard level (1 Amp) for metering.

Description
Function:
  • Current Measurement: CTs are used to step down high currents to a standard level (e.g., 1 Amp) for metering purposes. 
  • Voltage Measurement: VTs are used to step down high voltages to a standard level for metering purposes. 
  • Metering: The stepped-down values from the CTs and VTs are then fed to meters to measure current, voltage, power, and energy. 
  • CTR (Current Transformer Ratio):

    The CTR, in this case, 50-100-200 / 1 Amp, indicates the ratio of the primary current (50, 100, or 200 Amps) to the secondary current (1 Amp). 

  • Example: A CT with a CTR of 100/1 means that a primary current of 100 Amps will produce a secondary current of 1 Amp. 
  • Applications:
    • Power Distribution Systems: Used to monitor and measure electrical parameters in power distribution networks. 
  • High-Voltage Applications: Suitable for use in high-voltage systems where direct measurement of high currents and voltages is impractical. 
  • Types:
    • Pole-Mounted: Designed for installation on poles for outdoor applications. 
  • Indoor: Suitable for installation in substations or other indoor environments. 
  • Combined CT-VT Metering Units:

    These units combine both CTs and VTs in a single package for comprehensive metering.
