Voltage Transformers (VT/PT)

• Inductive Voltage Transformer (IVT)

• Capacitive Voltage Transformer (CVT)

Voltage Transformer Types

• IVTs work like regular transformers utilising the principle of electromagnetic induction and where energy is coupled from the primary coil to the secondary coil.

• A CVT is essentially an IVT with a capacitive voltage divider stack at the front-end together with a compensating reactor and is the preferred configuration at high voltages. Many CVTs also include a damping circuit.

Low Voltage Current Transformers

• Provide a scaled, isolated current signal for metering, protection, and PQ analysis, allowing safe instrumentation on LV feeders without interrupting the circuit.

• Iron core allows for tight coupling and high accuracy.

Medium Voltage Current Transformers

• Provide a scaled, isolated replica of primary current so meters can record load, demand, and energy consumption from MV feeders.

• Let you observe, meter, and protect MV feeders without ever exposing equipment or personnel to MV potential

• If you’re planning new switchgear, upgrading metering, or resolving protection issues, see how we can support you with the right LV or MV CTs
