Instrument Characteristics
| 1. | Due to the adoption of frequency conversion technology, accurate measurement can be ensured under strong electric field interference. |
| 2. | The instrument uses a Chinese menu operation, and the microcomputer automatically completes the entire measurement process. |
| 3、 | This instrument is also suitable for measuring the tgδ and capacitance of high-voltage electrical equipment in workshops, laboratories, and scientific research units; it is more convenient, simple, and accurate for testing the loss of insulating oil. |
| 4、 | This instrument can measure high-voltage electrical equipment that is ungrounded or directly grounded using the positive or reverse connection method. It can also measure the tgδ of capacitive voltage transformers and the capacitance of main capacitors C1 and C2. |
| 5、 | The instrument is equipped with a built-in high-voltage step-up transformer and incorporates safety protection measures such as zero-crossing closing and lightning protection. During the test, it outputs high voltages of different levels from 0.5KV to 10kV, making operation simple and safe. |
