Product Description

1000VA Transformer On Load Tap Changer AC/DC Parameter Tester For Substation

Introduction

 

    ZXYZ-JZ On Load Tap Changer AC Parameter Tester is mainly used to detect the excessive waveform of transformer on load tap changer at the substation site under the condition of switch with winding. The voltage level range of the switch is 10kV ~ 500kV. The test wiring is not limited by the wiring mode of transformer winding, and is suitable for three-phase and single-phase transformers of various wiring groups Test of over action waveform of on load tap changer such as reactor.

Features

1. AC/DC method to test the true transition waveform ( No Filtering processing), suitable for on site test of parameters like transition waveform, transition time, transient resistance and three-phase synchronization. 

2. It is easy to judge the on load tap changer when use AC test method. If the total transition waveform is continuous then the working condition is good

3. Can test 10kV~500kV voltage no matter what kind of winding wiring ways.

4. Built in power supply or external connecting power supply. Built in type can output three phase power with simple wire connection, external power supply can make high voltage test, zero sequence test

5. High speed sampling: over 200k/s/channel ( usually DC method speed is 10k/s). Large storage capacity, cache depth up to 8M byte FIFO.

6. With embedded computer and testing software, 10.4" color LCD, touch screen, printer, supporting U disk and USB keyboard and mouse

7. Meet the request of intelligent power grid operation and management system. The on-site operator can connect the sampler with tablet PC and transmit data via internet

8. Can transmit and export the data to office PC for further analysis or editing off line

9. Can work as a digital universal meter

10. Integrated structure, portable, simple wire connection
