Industrial Frequency Line Parameter Tester

The Transmission Line Power Frequency Parameter Tester is a high-precision instrument developed and manufactured by our company, specifically designed for measuring power frequency parameters of transmission lines. It can perform precise measurements on a series of power frequency parameters for transmission lines of various voltage levels, including: positive sequence impedance, positive sequence capacitance, zero sequence impedance, zero sequence capacitance, mutual impedance, coupling capacitance, inter-phase impedance, inter-phase capacitance, line-to-ground impedance, and line-to-ground capacitance, etc. The instrument boasts advantages such as a small size, light weight, high measurement accuracy, good stability, and easy operation and learning.,This new method completely replaces the previous approach of using multiple tables to measure circuit parameters. It features simple wiring, convenient testing and recording, significantly enhancing work efficiency. With a large-screen LCD as the display window, it offers graphical menu operations and Chinese prompts, displaying multiple parameters on a single screen. The human-machine interface is user-friendly, with simple and quick operation, making it suitable for users at all levels.FirstSelectedProduct.

I. Features

1The system can measure various parameters of transmission lines, including positive and zero sequence values, voltage and current RMS values, active power, and reactive power.

2The company now permits the use of external voltage and current transformers for extended range measurements.

3Wide-range voltage and current measurement circuit: voltage up to 75 can be measured0VNo need to shift gears for precision. It will not damage the instrument itself due to incorrect voltage gear selection; the current can pass directly.100AWide-range current testing ensures testing for various length lines.

4Large screen, high-brightness LCD display, full Chinese menu and operation prompts for friendly human-machine interaction; adjustable LCD brightness to accommodate all seasons; long-life conductive silicone keys for easier operation and better tactile feel.

5Users can submit test data at any time.232The interface is compatible with an external mini printer for printing results (printer is optional).

6Reserved computer communication capabilities for users of high-voltage measuring vehicles.RS232Serial ports, with expandable verification data upload functions, enable centralized data management.
