Transformer Ratio Meter

• Usage: Industrial
• Readings: 0.8000:1 to 1500.0:1
• Display: 6 Digit

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 reliable measurements.
