HVHIPOT GD6300 Large Capacity 18kV Capacitance and Dissipation Factor Tester Tan Delta Tester for Power Transformer

Product Description

GD6300 Capacitance and Dissipation Factor Tester Tan Delta Tester

General Information
 
GD6300 Capacitance & Tan Delta Tester is a high precision testing instrument for measuring capacitance and dielectric loss factor (tgδ) of various high voltage power equipment. The instrument is integrated structure, built-in dielectric loss test bridge, variable frequency adjustable power supply, booster transformer and high stability SF6 standard capacitor. It can test grounded equipments, not-grounded equipments, and completely-sealed CVT (Capacitor Voltage Transformer). Testing high voltage source is produced by the instrument internal inverter, then is used for tested objects after boosting by transformer and the frequency is 45 to 55Hz (or 55 to 65Hz) to avoid the electromagnetic interference from power frequency, in order to ensure the measuring accuracy. The test is automatically completed by microcomputer.

 
 
Features
 
 

1. Large LCD screen, easy operation.

1. Mass data storage

With built-in calendar chip and large capacity memorizer, 200 groups test result can be stored in chronological order, can view the history record at any time, and the results can be printed and outputted.

1. Multiple test mode

The instrument can use positive connection method and oppositive connection method to test separately.

1. Data management

The instrument data can be exported via U disk, saved as a TXT file, and can be directly viewed and managed on any PC.

1. Measuring multiple voltages at once

The instrument can measure the capacitance and dielectric loss value under high pressure of 0.2 times, 0.4 times, 0.6 times, 0.8 times and 1.0 times at one time

1. High speed sampling signal

Inverter and sampling circuit inside the instruments are digitally controlled, output voltage can be adjusted continuously.

1. Multiple protection functions to guarantee safety

With input voltage fluctuation, output short-circuit, over-voltage, over-current, temperature, etc. multiple protection, to ensure safety and reliability of instrument. The instrument is customized products, in order to meet the requirement of high power output, the instrument adopts the isolated power supply, so the grounding protection is canceled, so before the measurement, the grounding terminal of the equipment must be reliable grounded.
