What are the precautions for using a transformer volt-ampere characteristic tester?

发布时间：2022-10-10

The use of a transformer volt‑ampere characteristic tester must comply with the technical requirements for electrical safety and test‑procedure protocols stipulated in the applicable national standards. It is strongly recommended that users consult this manual; however, it does not supersede the relevant national standards governing electrical testing procedures. Users should also be aware that, when conducting tests with a transformer tester under high‑voltage conditions, all personnel involved must hold appropriate electrical‑testing qualifications.

When using a transformer voltage‑current characteristic tester, please note that the instrument should only be operated when all its parameters are within normal limits. If any abnormalities are detected, contact the manufacturer for repair immediately. When operating in special environments, adhere to the relevant national safety standards. In addition, always take care to prevent direct damage to the equipment caused by high voltage or large currents, and perform tests strictly in accordance with the user manual. Do not open the transformer tester; doing so will void the warranty. Any modifications, extensions, or improvements to the transformer tester are prohibited. We also recommend using only original manufacturer‑supplied accessories. Before completing the test, never disconnect the test leads; the power output indicator may be turned off only after the test connections have been disconnected. When using the transformer tester outside of a laboratory setting, ensure it is securely grounded with a grounding cable. Furthermore, during testing, one terminal of the high‑voltage section must remain grounded, while the secondary winding of the current transformer should not have a grounding point. The bushing in the transformer voltage‑current characteristic tester… CT After the test, restore the original wiring. The regulator switch and the output switch can be… OFF Connection and disconnection of the position, direction, and wiring. Before testing, the equipment must be reliably grounded.

Please inspect the transformer VA characteristic tester for any obvious external damage. Do not use the transformer tester in rainy or extremely humid conditions. In addition, ensure that all terminals connected to the transformer tester are at zero potential, and that all potentials are supplied by the transformer tester itself. Furthermore, when performing a turns-ratio test, make sure that the voltage is applied to… CT the secondary winding or PT on the primary winding; otherwise, the instrument‑transformer tester may be damaged. The instrument‑transformer volt‑ampere characteristic tester is applicable only to electromagnetic voltage transformers. Ratio and phase‑angle tests are performed. In particular, it is essential to reset the device to zero immediately after testing, and prolonged exposure under high voltage and large current is strictly prohibited. External step‑up voltage and current‑boosting equipment, as well as external… 380V When powering on, an appropriate protective system should be provided to ensure the safety of personnel and equipment. Of course, if the LCD screen does not display and the printer cannot operate normally, do not press any buttons on the control panel. During maintenance, first turn off the power switch; if the LCD still shows no display, the issue may be that the power input cable is not properly connected. The solution is to verify that the power cord is securely plugged in. If the mutual‑inductor VA characteristic tester fails to produce voltage or current during testing, check whether the voltage‑regulating switch (overcurrent protection) is engaged. If no current is output during ratio testing, verify that the test leads are connected correctly. If the voltage‑regulating switch trips upon startup, investigate the cause.
