Need a three-phase workflow? Start with TWA Advanced or TWA Standard for coordinated transformer connections and automated testing.

Need a simpler portable winding path? Compare RMO-TD and RMO-TT, or view RMO-TW for winding resistance and OLTC verification.

Build the Right Transformer Test Configuration

Send RCCE the transformer phase and winding configuration, desired test current, OLTC design, number of tap positions, and any motor-current, vibration, temperature, heat-run or turns-ratio requirements.

Final model, cable, accessory, pricing, availability and compatibility must be confirmed by RCC Electronics.
