Transformer Capacity Tester

Product Overview

The Transformer Capacity Tester is a specialized field testing device that enables rapid and accurate measurement of a transformer's rated capacity without applying high currents to the transformer. This product use wide-screen color LCD , English display, simple and quick menu operation, human-machine interface is very friendly. There is a built -in rechargeable battery inside the instrument and it can work without external power source. A fully charged battery can be continuously measured more than 100 sets of transformer. This is a multi-functional measuring instrument, which is equivalent to two common meters: such as active transformer capacity tester plus transformer parameter tester. It can be used for test transformer capacity, type, no-load current, no-load loss, load loss, impedance voltage and so on.

Application Scenarios

1. Electricity Audit (Anti-Theft): Verify the actual capacity of user transformers to combat electricity theft where users install transformers with lower capacity than their actual demand.

2. Transformer Acceptance and Quality Inspection: Conduct capacity verification on newly purchased or repaired transformers to prevent suppliers from substituting inferior products or falsely labeling capacities.

3. Capacity Expansion & Asset Management: Verify the accuracy of nameplate capacities on aging transformers to inform decisions on capacity upgrades or asset retirement.

4. Failure Analysis: Following transformer failures, validate whether the rated capacity matched operational requirements and analyze whether damage resulted from prolonged overloading.

Main Features:

• We can measure a variety of distribution transformer, power transformer capacity instead of the additional extra power. It is more convenient and efficient.
• Combined with the external power source, voltage, current regulator equipment etc, it can measures various transformer parameter such as no-load current, no-load loss, impedance voltage, load loss and so on.
• Characteristic test of transformer, test range is wide,flexible configured.only through the simple connection to current transformer and voltage transformer, test scope can be enlarged to high-grade power transformer.
• Short-circuit the terminals of cable,humanization design,with lock,easy connected to fasten units of transformation.
• Measure the transformer load current, load loss, short-circuit voltage, short circuit (load)losses, capability.
• Three measurement Methods.
• 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.
• 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.
• 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.
• 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.
• Comes with real-time clock, automatically recording test date, time, the preservation of favorable results, management.
• Panel-type thermal printer, the scene quickly print test results.
• 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.
• Allows an external voltage transformer and current transformer for extended range of measurement, any measurable parameter is the test product.
