Tester 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 also has advantages of convenience, simplicity, and accuracy for insulation oil loss testing. |
| 4、 | This instrument can measure ungrounded or directly grounded high-voltage electrical equipment using positive or reverse connection methods. It can also measure the tgδ of capacitive voltage transformers and the capacitance of main capacitors C1 and C2. |
| 5、 | The instrument is internally equipped with a 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. |
