Megger TRS1Plus Transformer Ratio Standard w/ NIST

Features

• Replaces PN 550050 and 550055
• High accuracy 0.01 %
• Rugged design for field use
• Versatile, step-down and step-up ratio
• Designed to be used with large test clips or banana jack inputs
• Four-terminal Kelvin - no lead compensation required
• Universal standard for use with all ratiometers
• Includes ratios from 1 to 2048 step down, and 1 to 32 step up

The Megger TRS1 transformer ratio standard is designed for use with ratio meters as a high‑accuracy reference standard. It operates over an input frequency range of 50 to 240 Hz, supports step‑down voltages below 275 V AC, and step‑up voltages below 8 V AC, and is compatible with single‑phase and three‑phase ratio meters. It may be used as a laboratory calibration standard or as a portable check standard for field ratio and phase verification of any ratio instrument in calibration environments where precise ratio transformation is required.

What's in the Box

• Step Up And Step Down Ratio Standard
• Certificate of Calibration traceable to NIST is included (CERT-NIST)
