Product Overview

Currently, conventional methods are widely used in the power system.QJ44The type double-arm DC bridge measures contact resistance, while the test current of such a bridge is onlymAIt is difficult to detect defects in the reduction of the cross-sectional area of the circuit conductors. When measuring the contact resistance of a high-voltage switch's conductive circuit, the measured value is several times larger due to the influence of the oil film and oxidation layer between the contacts, failing to accurately reflect the actual contact resistance.

For this, the new Ministry of Power standardsDL/T845.4—2004"General Technical Conditions for Resistance Measurement Devices: Circuit Resistance Meters" and the new verification regulationJJG1052-2009Regulation for Calibration of Circuit Resistance Meters and Direct Resistance Meters specifies that the measuring current for contact resistances of switches (isolated), circuit breakers, etc. shall not be less than direct current.100AInsufficient Chinese content provided.60SRegulations are in place to ensure the accuracy of test results.

ED0303B-100The ergonomic design of the contact resistance tester's operation panel aligns with operational habits. It utilizes high-frequency switching power supplies and digital circuit technology, making it suitable for measuring the circuit resistance of switching control devices.

Test current is conducted using the recommended DC standard by the national standards authority.100AAvailable in DC100AIn the case, the loop resistance was directly measured, with the test results displayed on a large LCD screen.LCDThe product showcases, featuring functions such as data storage, output printing, and time setting, among others.50AGear options available for users; customizable test time, with extended set time599S,Significantly greater than the standard requirements60S; is domesticPlease provide the content of the company news you would like to be translated.Achievable0.01μΩ resolution and highly stable contact resistance tester, outperforming imported high current micro-ohmmeters.
