The ZC-201A transformer power analyzer developed by our company can measure the no-load current, no-load loss, short-circuit voltage and short-circuit (load) loss of the transformer, and can also carry out harmonic test to analyze 31 harmonics. The instrument can automatically switch the measuring range inside, allowing a wide range of measuring voltage and current, and simple wiring. In the no-load and load test of three-phase transformer, the instrument can automatically judge whether the wiring is correct and display the vector diagram of three-phase voltage and current.
Zc-201a single transformer can also complete the measurement of load test under the full current of distribution transformer below 1000KVA; the measurement of load test of distribution transformer below 3150kva can be completed under the third rated current (under the third rated current, the instrument can be converted to the load loss parameter under the rated current). All test results are automatically corrected.
In addition, the instrument can automatically carry out a variety of corrections, such as: waveform correction, temperature correction, non rated voltage correction, non rated current correction, etc., so that the accuracy of the test results is higher.
Zc-201a transformer power analyzer has powerful functions, simple operation and few faults. However, it doesn't rule out the failure due to improper use, so here are some simple troubleshooting methods:
Startup without display: first shut down, open the fuse box of AC 220V socket on the backplane, check whether the fuse is burnt out, and replace the fuse.
The screen suddenly goes black: press the reset key to start the measurement again.
Incorrect measurement and calculation results: check whether the external wiring is operated according to the instructions, whether there is poor contact or wrong connection; the relevant parameters are set incorrectly.
If the measured voltage is normal and the current display is zero, please check whether the current guard fuse is broken.
When wiring with double meter method, it prompts wiring error. Please check the field wiring carefully according to the instruction manual. If the wiring is correct, please change the A / C two-phase of the voltage regulator and try again, so as to determine whether the field three-phase power phase sequence is wrong.
The result of no-load test has a large jump, please note that the test power supply needs to be separated from the power supply used by high-power impact equipment such as workshop traveling crane.
The above is the troubleshooting method of zc-201a transformer power analyzer. If you don't understand anything when you use it, you can consult our online customer service at any time~
