High-Precision Testing Solution for Power Equipment Maintenance
Date: April 28, 2026Source: Official Manufacturer Release
Overview
With the continuous upgrading of global power systems and standardized preventive maintenance, accurate and efficient insulating oil testing has become critical to ensuring the safe, stable operation of transformers, reactors and other high-voltage equipment.
We are pleased to launch the MOEORW-WBJ83 Fully Automatic Insulating Oil Dielectric Loss Factor and Volume Resistivity Tester, developed strictly in accordance with GB/T 5654-2007 and IEC 60247-2004. It provides a reliable, high-precision testing solution for power grids, industrial laboratories and engineering services worldwide.
Core Advantages*
-
Fully Automatic & Intelligent Operation
Adopting high-precision digital measurement technology, the tester supports one-key fully automatic testing. It independently completes heating, temperature control, data collection, calculation, display, storage and fast printing, greatly reducing manual operation and human error. The large color touch screen delivers intuitive human-machine interaction for clear parameter setup and result reading.
-
Superior Structure & Stable Measurement
Equipped with a standard three-electrode oil cup (2mm gap), it effectively eliminates interference from stray capacitance and leakage current, ensuring high repeatability and reliability. The built-in standard capacitor maintains stable capacitance and loss values unaffected by ambient temperature and humidity, enabling long-term high-precision testing.
-
Efficient & Safe Heating System
Using medium-frequency induction heating, the instrument provides non-contact, uniform and rapid heating with precise control up to 120℃. Multiple safety protections - including high-voltage cut-off when the cover is opened and electrode short-circuit alerts - fully protect operators and equipment.
