Multi-Frequency Induced Voltage Withstand Tester

The MOEORW-WGM11 Multi-Frequency Induced Voltage Withstand Tester (also referred to as Frequency Multiplier Power Supply Unit, Induced Voltage Test Device, or Variable-Frequency Multiplier Generator) is a new-generation electronic frequency-multiplier test instrument developed in strict accordance with DL/T 848.4-2004 "General Technical Specifications for High-Voltage Test Devices." Employing power electronic frequency conversion technology with an embedded computer and a 7-inch color LCD touchscreen, this unit delivers test voltages at 50Hz, 100Hz, 150Hz, 200Hz, or user-defined frequencies. It is specifically designed for induced voltage withstand testing of transformer windings - including turn-to-turn, layer-to-layer, section-to-section, and phase-to-phase longitudinal insulation - as well as for induced voltage testing of instrument transformers.

As a variable-frequency multiplier generator, it completely abandons the traditional three-phase five-limb iron-core structure, reducing overall volume by over 60% and significantly decreasing weight. It can be carried and operated by a single person, making it especially suitable for power engineering units that require frequent site-to-site relocation.
