Product Overview

Currently, conventional methods are widely used in power systems for measuring contact resistance.QJ44Type double-armed DC bridge, and the test current for such bridges is onlymAIt is challenging to detect defects in the reduced cross-sectional area of circuit conductors. When measuring the contact resistance of high-voltage switch conductive circuits, the measured values are several times larger due to the influence of oil films and oxidation layers between the contacts, failing to accurately reflect the actual contact resistance values. In response, the Ministry of Power has established standards.SD301—88"Communication"500KVThe "Procedures for Power Equipment Handover and Preventive Testing" and the new edition of the "Procedures for Preventive Testing of Power Equipment" specify that the measuring current for the contact resistance of circuit breakers and disconnecting switches shall not be less than direct current.100ARegulations are in place to ensure the accuracy of the test results.

ED0303AThe circuit resistance tester is in compliance with the new electrical execution standards.DL/T845.4-2004Combining high-frequency switching power supply technology with digital circuit technology.

ED0303AThe circuit resistance tester is suitable for measuring the circuit resistance of switch control equipment.

ED0303AThe circuit resistance tester uses the DC current recommended by the national standard.100APlease provide the Chinese content to be translated.100ADirectly measured the loop resistance and displayed it numerically.

ED0303AThe circuit resistance tester offers precise measurement and stable performance, meeting the requirements of on-site high-voltage switch maintenance for power and supply departments and circuit resistance testing in high-voltage switch factories.
