Discover high-precision testing instruments designed for reliable performance, safety, and compliance across power generation, transmission, and distribution applications.

TRM Series

TRM Series

Transformer Winding Resistance Meter

TRM 25+ and TRM 50+ are advanced precision Winding Resistance Meters from SCOPE, designed for both field and factory testing of power transformers up to 500 MVA. These instruments provide accurate resistance measurements of transformer and rotating machine windings, with results displayed on a clear 5.7-inch TFT screen. Built for reliable operation in live EHV switchyard environments, they offer simultaneous measurement of multiple windings, automated tap-change testing, and demagnetization functions to significantly reduce testing time. With enhanced safety features and protection against back-EMF from large inductive windings, the TRM series ensures accurate, efficient, and dependable transformer testing.

TTRM Series

Transformer Turns Ratio Meter

TTRM 302 & TTRM 102 is a state-of-the-art Three-Phase Transformer Turns Ratio Meter from SCOPE, designed for field and factory testing of power, instrument, and distribution transformers. The instrument accurately measures turns ratio, ratio deviation, phase angle deviation, and magnetizing current while also detecting tap positions under charged switchyard conditions. It automatically identifies transformer vector groups and provides highly accurate measurements using selectable AC test voltages. Equipped with a touch-screen TFT display, thermal printer, and internal memory, TTRM enables easy data storage, analysis, and report generation through PC connectivity, making transformer testing faster, simpler, and more reliable.

MagD Series

MagD Series

Step Up Transformer

MagD is an advanced Step-Up Transformer from SCOPE, specially designed for testing and evaluation of instrument transformers. It is used to verify transformer performance during commissioning, maintenance, or after fault conditions, ensuring accurate outputs to protective relays. The unit enables easy plotting of excitation curves with its built-in voltmeter and ammeter, eliminating the need for external measuring devices. MagD also supports transformer core demagnetization and turns ratio testing, making it a versatile and essential tool for comprehensive instrument transformer testing and maintenance.
