High voltage dielectric loss tester manufacturer

Product Introduction
TPJSC-D frequency conversion anti-interferenceHigh voltage dielectric loss tester manufacturerIt is a new type of dielectric loss tester successfully developed by Yangzhou Topu Electric Technology Co., Ltd. With the continuous deepening of urban and rural power grid renovation, there are more and more higher substations. The inversion method and phase shifting method can no longer meet the on-site testing needs. Different frequency measurement (frequency conversion) can eliminate interference by converting 50HZ to other frequencies. However, due to limitations in electronic technology, the frequency after frequency conversion is generally at a certain distance from 50Hz. The capacitance values cx and tg δ under 50Hz conditions are simulated and converted, which is at a certain distance from real power frequency testing. Especially for a few test samples, there are significant errors in the measured data. After comprehensive comparison, a new type of dielectric loss measuring instrument has been developed, which does not change the frequency principle and can obtain the capacitance values cx and tg δ under 50Hz conditions, improving measurement reliability and accuracy, * suppressing electric field interference, and meeting the requirements for use under electric fields.
TPJSC-D frequency conversion anti-interferenceHigh voltage dielectric loss tester manufacturer​bodySmall size, light weight, easy to carry. Flexible scalability, connected to computers through interfaces, using software attachments for instrument upgrades, user-friendly design, and fully automated operation. This instrument is suitable for on-site testing in power stations with interference of 500kV and below.

Product features
1. There are multiple measurement methods available, including positive/reverse wiring, internal/external standard capacitors, CVT, and internal/external test voltages for measurement. Positive wiring can measure high voltage dielectric loss.
2. When measuring a capacitive voltage transformer (CVT), no other external equipment is required.
3. Built in SF6 standard capacitor, tgδ<0.005%, Less affected by air humidity.
4. Good anti-interference effect, built-in automatic tracking variable frequency power supply, can effectively eliminate the influence of strong electric field interference on measurement, suitable for strong interference field testing in power stations below 500kV.
5. When there is a high voltage short circuit or sudden power outage, the instrument can quickly cut off the high voltage and issue a warning message.
6. Good measurement repeatability and good voltage linearity (measurement accuracy is not affected by voltage).
7. Large screen LCD display, easy to operate. Integrated structure, easy to carry.
8. The instrument comes with a printer that can print test data.
9. Connect the high-voltage cable to the test sample to ensure safety; The instrument is not grounded and the alarm is triggered. The safety measures are complete.
