Product Introduction

Three-phase dc resistance test instrument (hereinafter referred to as direct resistance instrument) is the latest generation product of transformer dc resistance measurement, and is designed to optimize the large-capacity transformerthree-phase dc resistance around the group. Transformer three-phase dc resistance around the group can be tested simultaneously. For transformer with load regulating voltage, discharge can be eliminated and straight pick up switch can be adopted. Measurement time is one third of that of traditional Single phasemeasurement standard, which can greatly reduce working time and labor intensity. The direct resistance meter adopts large screen liquid crystal display, with a clear and intuitive graphical interface in Chinese, and operation is very simple. Equipped with panel printer and large capacity non-volatile memory, measurement results can be easily stored and printed. Testdata is stable, fast and repeatable, making it a standard choice for dc resistance in scenemeasurement transformer.
