Pontenital transformer


Voltage and potential transformers are used to measure voltage (potential). The secondary voltage is substantially proportional to the primary voltage and differs from it in phase by an angle that is approximately zero. Voltage and potential transformers that are designed for monitoring single-phase and three-phase line voltages in power-metering applications are used mainly as step-down devices. They are designed for connecting line-to-line or line-to-neutral in the same way as ordinary voltmeters.

The secondary voltage has a fixed relationship to the primary voltage so that a change in potential within the primary circuit is monitored accurately by meters connected across the secondary terminals. monitoring single-phase and three-phase line voltages in power-metering applications are used mainly as step-down devices.
