Raytech mini-ATOS

Raytech mini-ATOS is a winding resistance and turns ratio test set offered for rental, equipped with a built-in fully automatic multiplexer. It supports excitation current, phase displacement, transformer winding connection and vector group detection, demagnetization via SPP, DRM, core magnetic balance, leakage reactance, FRSL, and tap changer motor current measurements.

Product Overview

• Winding resistance and turns ratio testing with dual power supply for transformers.
• Built-in automatic multiplexer and demagnetization using Raytech SPP method.
• Measures excitation current, phase displacement, and vector group detection measurement.
• Supports DRM, core balance, leakage reactance, and FRSL measurements.

Raytech mini-ATOS delivers comprehensive transformer diagnostics, combining winding resistance and turns ratio verification with a built-in fully automatic multiplexer. It measures excitation current, phase displacement, and performs vector group detection, demagnetization via SPP, DRM, core magnetic balance, leakage reactance, and FRSL, supporting precise assessments for maintenance and commissioning and testing.

Target Market

Used by utility substation teams, industrial maintenance departments, transformer service companies, and commissioning engineers for transformer diagnostics, condition assessment, and tap changer evaluation in field and shop environments where accurate winding resistance, turns ratio, and related measurements are required.
