Capacitor voltage transformer TYD 126 - 550 kV Reliable and safe outdoor instrument transformer CVT oil-insulated capacitor voltage transformer with safe and stable ferro-resonance damping circuit. This makes CVTs more economical than the wound voltage transformers under high voltage (over 100 kV), as the latter one requires more winding and materials. The high quality, state of the art, automated manufacture of the capacitor elements provides consistent quality to ensure long term reliability and Coupling capacitor voltage transformers (CCVTs) commonly have double secondaries for both phase and 3V0 voltages (see Figure 2c). Capacitor voltage transformers Abstract: The paper describes in a general way that class of voltage transformer which the authors propose should be termed the "capacitor voltage transformer" as distinct from the conventional electromagnetic voltage transformer. It is of single-phase design and intended for connection between phase and ground in networks with insulated or direct-grounded neutral points. The calculator below can be used to calculate reactive power consumption in transformer at full load and rated voltage. A CVT or CCVT, Capacitor Coupled Voltage Transformer, is made with two capacitor sets acting as a voltage divider that brings the line, actually the phase, voltage down to around 12-20 kV then this voltage is fed to a relatively small transformer for the voltage signal to be processed. Capacitor Voltage Transformer TYD is designed for revenue metering and protection in high voltage networks. Capacitor Voltage Transformers convert transmission class voltages, 72.5 - 1100 kV, to standardized low and easily measurable values with high level of fidelity, used for metering, protection and control of the high voltage system. Three VTs or three CCVTs, such as shown in Figure 2a and 2c , pass positive-, negative-, and zero-sequence voltage . To calculate the reactive power due to just the shunt magnetizing impedance, use %load as ‘no load’. When the customer owns the transformer then the reactive power drawn by the power transformer will be metered by the utility. As the majority of the voltage drop is on C 1, this reduces the required insulation level of the voltage transformer.
