Your Megger TTR20 Doesn’t Need Guesswork.

It Needs Calibration — Without the Runaround.

Your organization trusts the Megger TTR20 TTR-20 Transformer Turns Ratio Test Set to tell you the truth.

Megger TTR20 TTR-20 Transformer Turns Ratio Test Set Calibration

Quick Overview

  • What it is: Portable digital transformer turns ratio tester
  • Typical use: Field or lab measurement of transformer turns ratios, phase angles, and excitation current
  • Status: Active (fully available and in production)

A Megger TTR20 TTR-20 Transformer Turns Ratio Test Set doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the TTR20, the specification limits, and the standards behind them.

FAQ

Typically, the Megger TTR-20 should be calibrated annually (every 12 months), or according to the company’s internal quality procedures and regulatory requirements.

You will know the TTR-20 needs to be calibrated if:
- The annual calibration period has elapsed.
- Measurement results are inconsistent, inaccurate, or outside expected tolerances.
- The device has experienced physical shock, damage, or exposure to adverse environmental conditions.
- Internal self-checks or calibration reminders (if available on the device) indicate calibration is due. Always follow manufacturer guidelines and internal calibration control systems for scheduling.
