PT Test Companion (P02-0803)
TESCO’s Potential Transformer Test Companion (Catalog No. P02-0803) is a two-piece, True RMS voltage measurement system that enables safe measurement of primary distribution voltages up to 40kV. Using a fiber-optic link, a high-voltage sensor mounted on a hot stick (hot stick not included) communicates measured voltage information to a receiver unit at ground potential, providing complete electrical isolation for enhanced operator safety.
Description
Integrated with the Meter Site Analyzer (Catalog No. 6330), the system delivers primary voltage measurements for in-service PT/VT ratio verification, waveform capture and recording. The 6330 uses the primary voltage measured by the PT Test Companion and the secondary voltage measured by the analyzer to automatically calculate and compare the PT/VT ratio against the transformer’s nominal ratio, enabling rapid assessment of PT/VT performance without removing the transformer from service.
Components included in kit: 40 kV Volt LiteWire, fiber optic linked sensor, analog output , hook, 7-047 insulated electrode, P00-RA-BNC 6330 probe adapter cable (calibrated by TESCO for usage with the 6330) and Pelican case. Hot stick not included.
