Digital Transformer Ratiometer TR8703
The Transformer Ratiometer TR8703 is a lightweight, rugged, portable instrument designed for onsite testing of power, potential and current transformers. No user calibration, range selection, hand cranking or tedious balancing is required. During each test cycle, the TR8703 automatically checks for H/X lead reversal, continuity of tested circuits/windings (if configured) and short circuit conditions (high current).
Features:
- Measures power transformers, VT/PTs and current transformer CT turns ratios.
- Two internal NiMH batteries provide up to 10 hours of continuous operation.
- Direct reading LCD alphanumeric display.
- Display warns of incorrect lead connection, reverse polarity, open and short circuits.
- USB port facilitates configuring the instrument and downloading test results.
- Stores up to 10,000 test results in internal memory.
