Transformer Ratio Meter
The Transformer Ratio Meter is a portable digital
transformer ratio meter designed for on-site testing of power, potential and
current transformers. When connected to a non-energized transformer, it
accurately measures primary to secondary turns ratio, while simultaneously
displaying polarity and excitation current.
Transformer Ratio Meter is fully automatic and uses an ANSI/IEEE complaint
test method. No user calibration, range selection, hand cracking or tedious
balancing is required. Measurements are displayed quickly and accurately.
This type of ratio meter is designed with operator safety in mind. Tests
are performed at low voltage and, unlike other ratio meters, step-down
excitation is employed.
These transformer ratio meters provide the user with years of accurate and
