Product Introduction:
Developed by Hubei YitianchengThe YTC6450 transmission line parameter tester is a fully functional upgraded product based on our company's original high-power line frequency parameter abnormal frequency testing system (split type device). According to the "DL/T 1119-2010 General Technical Conditions for Transmission Line Frequency Parameter Testers" and the "DL/T 1179-2012-1000kV AC Overhead Transmission Line Frequency Parameter Measurement Guidelines", the abnormal frequency power supply and testing host are integrated into a meter source integrated testing device. That is, functions such as inter frequency power supply and its output control, isolation transformer and its gear switching, test wiring transformation, grounding switching operation, signal measurement and acquisition, data analysis and calculation are all centralized in the same chassis.
The achievable testing items (maximum configuration) of this device cover all the required content for parameter measurement and power frequency parameter measurement of various types of power transmission lines before parameter measurement.

Product features:
1. Suspended at the beginning and end of the tested line - measurement of static induced voltage and grounding current of the line;
2. Short circuit grounding at the end of the tested line - measurement of electromagnetic induction voltage and electromagnetic interference current of the line;
3. Phase verification of three-phase lines under high induced voltage - the end of the line is a bridge busbar or GIS composite electrical device;
4. Test the insulation resistance of each phase of the line, verify the phase, and measure the DC resistance of the line;
5. Positive sequence impedance, zero sequence impedance, positive sequence capacitance, zero sequence capacitance, and equivalent capacitance of three-phase transmission lines;
6. Zero sequence mutual impedance and zero sequence coupling capacitance between multiple circuits on the same pole or parallel lines;
7. Analysis of the impact of imbalance and asymmetry between multiple circuits on the same pole or parallel lines;
8. Positive sequence impedance, zero sequence impedance, positive sequence capacitance, and zero sequence capacitance of two-phase transmission lines;
9. Zero sequence mutual impedance and zero sequence coupling capacitance between circuits of parallel two-phase transmission lines on the same pole;
10. The built-in program controls the transformation of test wiring, the output of isolation transformers, data sampling, and automatic calculation and analysis in sequence.
11. The external dimensions of the equipment comply with ergonomic principles for transportation, on-site loading and unloading, and movement. The weight of the entire testing device is controlled within 60-85kg according to the model specifications.
