Remove Residual Core Magnetism Before the Next Critical Test

The DEM60R provides fully automatic demagnetization for single- and three-phase transformers, helping establish a more reliable magnetic starting condition after DC testing or service events.

When Should a Transformer Be Demagnetized?

Residual magnetism can affect the next measurement or operating event. These are the most common reasons to add a controlled demagnetization step.

After Winding Resistance Testing

DC test current can leave the transformer core magnetized. Demagnetize before moving to tests that may be influenced by core remanence.

Before Energization or Diagnostics

Establish a more consistent starting condition before energization, excitation-current testing, frequency-response work or related diagnostics.

When Final Core Condition Matters

Use a dedicated process when the procedure requires automatic demagnetization plus information about initial and remaining magnetic flux.

Dedicated transformer demagnetizer

DV Power DEM60R

A fully automatic instrument for demagnetizing single- and three-phase power transformers using controlled current reversal and a progressively decreasing current sequence.

  • Demagnetization current up to 60 A DC
  • Primary- or secondary-side connection
  • Automatic discharge of stored energy
  • Initial and remanent-flux information

Dedicated DEM60R or a built-in function?

Choose a dedicated demagnetizer when three-phase automation, higher demagnetization current or remanent-flux evaluation is required. For combined winding-resistance and demagnetization workflows, ask RCCE whether another DV Power platform better fits the complete test procedure.

Confirm the Correct Demagnetization Approach

Send RCCE the transformer type and rating, winding configuration, primary and secondary voltages, available connection points, previous DC tests and whether remanent-flux documentation is required.

Final model suitability, accessories, pricing, availability and service scope must be confirmed by RCC Electronics.
