HM5003 Transformer Capacity Tester Setting Introduction Video
Product Overview & Application Scenarios
The HM5003 Transformer Capacity Load No Load Tester is a new instrument developed by our company's R&D team specifically to address issues of non-compliant power users evading basic electricity charges and illegally increasing capacity. It is a high-precision instrument designed for measuring transformer capacity and characteristic parameters. This product features a large color LCD display with English interface, offering simple and efficient menu-driven operation with a user-friendly human-machine interface. The instrument incorporates a high-efficiency rechargeable battery, enabling operation without an external power source.
Application Scenarios
1. Electricity Auditing (Anti-Theft): Verify the actual capacity of user transformers to prevent electricity theft through the installation of under-rated transformers below actual demand.
2. Transformer Acceptance and Quality Inspection: Validate the capacity of newly purchased or repaired transformers to prevent suppliers from substituting inferior products or falsely reporting capacity.
3. Capacity Expansion and Asset Management: Verify the accuracy of nameplate capacities on aging transformers to inform decisions on capacity upgrades or asset retirement.
4. Failure Analysis: After transformer failures, validate whether rated capacity met operational requirements and determine if damage resulted from prolonged overloading.

Functional characteristics
1.Measure the transformer load current, load loss, short-circuit voltage, short circuit (load) losses, capability.
2.Three measurement Methods.
3.Do three-phase transformer no-load, load test, the instrument can automatically determine the wiring is correct, and shows three-phase voltage and current vector map.
4.Single machine can do the following 100KVA distribution transformer full load current experiment; in one third of the rated current, complete 250KVA distribution transformer load the following test (in one third of the rated current, the instrument can be converted to load loss under rated current parameters, the machine is mainly used in the test bed
with integrated supporting the use of transformers.
5.All the related test results are automatically corrected. Instrument can automatically such as: the waveform correction, temperature correction, non-rated voltage correction, calibration, and other non-rated current correction, so that more accurate test results.
6.320x240 large screen, high brightness LCD display, full Chinese menu and operations to achieve prompt and friendly man-machine dialogue, touch buttons make the operation more convenient, wide LCD with brightness adjustment, can be adapted to the various summer and winter season.
7.Comes with real-time clock, automatically recording test date, time, the preservation of favorable results, management.
8.Panel-type thermal printer, the scene quickly print test results.
9.Data (test sample set, the measurement results, the test of time, etc.) with power-down storage and browsing features, you can store 500 set of experimental results with computer on-line data transfer.
10.Allows an external voltage transformer and current transformer for extended range of measurement, any measurable parameter is the test product.
