Category: DC Resistance Tester

Product Description

The DC resistance test of transformer windings is an essential test item after transformer handover, major repair, and tap changer adjustment. The regulations stipulate that during transformer handover, major repair, minor repair, tap position change, fault inspection, and preventive tests, the DC resistance of transformer windings must be measured. The purposes are:

　　1.To check the welding quality of internal conductors and leads in the windings;

　　2.To check whether the contacts at each position of the tap changer are good;

　　3.To check for any broken wires in the windings or leads;

　　4.To check the correctness of parallel branches, whether there is a situation where one or more breaks occur in a winding made of several parallel wires;

　　5.To check for short circuits between layers and turns.

　　The YTC316-10 DC Resistance Rapid Tester adopts power supply technology and features fast measurement, compact size, convenient use, and high measurement accuracy. It is a device for measuring the DC resistance of transformer windings and high-power inductive equipment.

　　The YTC316-10 DC Resistance Rapid Tester complies with the national standards GB6587-86 "General Outline of Environmental Testing for Electronic Measuring Instruments" and GB6593-86 "Quality Verification Rules for Electronic Instruments".

Product Features:

1.Fast measurement speed: This instrument outputs a constant current of 10A. During measurement, it can effectively compensate for the current inertia of large inductive equipment, accelerate core saturation, thereby shortening charging time and improving measurement speed. It is hundreds of times faster than traditional single-arm and double-arm bridges.

2. High accuracy: This resistance tester uses advanced microcontroller-based high-power, high-precision programmable constant voltage and constant current technology, maintaining a relatively stable charging current for inductive loads, with stable anti-inductance capability and strong anti-interference ability, thereby ensuring measurement accuracy.

3、This instrument has a high degree of intelligence, compact structure, and novel and reasonable layout. In addition to adopting the advanced four-terminal measurement method, it also uses dual-channel programmable comparison analysis, automatic zero calibration, and is equipped with anti-arcing and data analysis circuits. It automatically outputs and prints measurement data, with menu operation and human-machine dialogue, making operation and reading very convenient.
