The measurement of DC resistance is a test item in the manufacturing of inductive coils such as transformers, transformers, reactors, and electromagnetic operating mechanisms, which includes semi-finished and finished product factory testing, installation, handover testing, and preventive testing by power departments. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of inductive coils, and eliminate hidden dangers in device operation.
It can be used to check single-phase defects in transformers or in situations where there is no three-phase electricity on site. The instrument can record data from three single-phase measurements and calculate the transformer's no-load current, no-load loss, impedance voltage, and load loss based on different connection methods of the transformer
KDZD820 battery online monitor is an online monitoring system based on battery internal resistance, battery terminal voltage, battery total voltage, battery total current and the temperature of the environment where the battery is located, which monitors battery performance and status in real time, analyzes the development trend of battery performance and judges the service life of the battery.
