Musktool-DTR1002P-Transformer Comprehensive Test System（DC Resistance+Turn Ratio）Integrated Tester
Functional Characteristics
1)Supports one-time wiring to complete the direct resistance test and ratio test, convenient and efficient operation. 2)The direct resistance test function is suitable for Yn-type, Y-type and △-type windings, and it can test and calculate the three-phase unbalance rate through the three-phase automatic method; the maximum output current is up to 20A, which can satisfy the demand for the test of low-voltage coils of transformers in the distribution network with very low resistance value. 3)The ratio test function covers three-phase, single-phase and Z-type transformer test, with PT/CT ratio and polarity test capability, while supporting blind test function. 4)Equipped with embedded Linux operating system, high security, smooth operation and easy to operate. 5)Built-in high-capacity lithium battery and equipped with a charger, power supply time lasting. 6)Adopting A7+M4 dual-core architecture, taking into account the real-time measurement and smooth operation. 7)Equipped with an industrial-grade 7-inch large screen, the display style is fresh and simple,bringing a comfortable and convenient human-computer interaction experience. 8)Equipped with a variety of wired and wireless communication interfaces, easy to expand the instrument function |
Technical Indicators
Panel Description
1)Terminals used for direct resistance and ratio testing: high-voltage to the high-voltage side of the transformer; low-voltage to the low-voltage side of the transformer. 2)Capacitive touch screen: display size 7 inches; resolution 1024 × 600. 3)Lithium battery charging socket: Insert the matching three-core power cord into the instrument and charge the instrument after connecting to 220VAC mains power; the fuse holder is integrated with the socket, and the specification of the fuse is 250V/2A, with the size of φ5mm×20mm, and the same specification of the fuse should be used. 4)Power on/off button: short press for 2 seconds to turn on the instrument; long press for 3 seconds to turn off the instrument. 5)Grounding terminal: the instrument must be reliably grounded; the site grounding point may be painted or rusted and must be cleaned. 6)Charging indicator: red light, indicating that the instrument is charging. Green light indicates that the charging of the instrument is completed. 7) U disk interface: external U disk, used to store test data; in the storage process, it is strictly prohibited to dial out the U disk. 8)External communication port: can be used to connect to external PC2 for data communication and transmission or external specialized module for function expansion. 9)Printer: Prints test results. |
