Product Overview
The Taiwan-style DC resistance tester is a specialized tool for measuring the DC resistance of transformer windings and high-power inductive equipment in the power industry. Designed based on the DL/T845.3-2004 standard, this instrument features a large storage capacity, capable of holding up to 255 sets of data. The unique four-wire measurement method effectively enhances the accuracy of low-resistance measurements.
Application Scenario
The measurement of direct current resistance is of great significance for the manufacturing, factory testing, installation, handover testing, and preventive testing of inductive coils like transformers, current transformers, and reactors. Desktop direct current resistance testers can quickly identify potential issues in materials selection, welding, and connection areas, ensuring the safe operation of electrical equipment.
