Introduction - Raytech mini-ATOS Instruction Manual

3 Introduction

The Raytech precision mini–Automatic Transformer Observation System (mini-ATOS) is a
professional multifunctional power transformer and substation diagnosing test instrument
developed by Raytech engineers. It is designed for a high degree of accuracy and ease of use.
This compact and intelligent instrument can perform many routines and advanced tests such as
Winding Resistance (WR), Dynamic Resistance Measurement (DRM), Turns Ratio (TR),
Frequency Response of Stray Losses (FRSL), Magnetic Balance, and other diagnostic
parameters. With the built-in fully automatic multiplexer, only a one-time connection is required for
nearly all functions which saves a considerable amount of time. The portable, rugged case is
perfect for use anywhere onsite or in a laboratory. It is specially designed for fast and easy
measurements with the well-known high precision and quality of all Raytech instruments.
INFO:
The mini-ATOS field case is a waterproof design (IP67). A pressure
regulator activates when the case is opened to compensate for
atmospheric pressure changes.
