Product Introduction
MOEORW-WBD21 is a high-precision short-circuit impedance tester designed for on-site rapid test. It can measure short-circuit impedance, short-circuit reactance, three-phase impedance voltage, inductance and other parameters, with automatic data collection, calculation, locking, printing and storage functions. The instrument uses large-screen LCD Chinese menu operation, simple wiring, high automation, stable data, and is widely used in power system, transformer production and maintenance units to quickly judge the health status of transformer windings.

FAQ
Q1: Does this instrument need an external regulator?
A: No, it can be directly powered by AC220V, with built-in test power supply, no external regulator is required.
Q2: Can three-winding transformers be tested?
A: Yes. Select high-low, high-medium, medium-low measurement positions, connect the test wire to the corresponding side, short the secondary side, and open other windings.
Q3: How to operate when using single-phase test for three-phase transformer?
A: Input 1/3 of the rated capacity, wiring and operation are the same as single-phase transformer test.
Q4: What is the basis for judging the test results?
A: Impedance error within ±2%: normal operation; ±2%–±5%: regular detection; >±5%: stop operation for maintenance.
Q5: How to save and export data?
A: Press SAVE to save to the instrument; return to the boot interface, insert U disk, press SAVE to export to U disk.
