Protective Circuit Vector Analyzer

Product Overview

As the power industry evolves and microcomputer integrated automation products are widely adopted, the correctness of the wiring in protective and metering circuits directly impacts the stability of the power system and the accuracy of electricity billing, both of which are crucial aspects of the power system.

Due to the numerous connections involved in protective devices and high-voltage measuring equipment, incorrect wiring is prone to occur and often goes unnoticed. This is especially true for the complex wiring of differential protection, where both high and low sides may be simultaneously introduced, and different connection groups are involved.Extreme.Our company, in response to the need for on-site testing, has timely developed a multi-functional vector analyzer to address potential issues of misalignment that may not trigger or fail to activate during routine operation, thus eliminating significant hidden dangers.

The Protection Circuit Vector Analyzer is a multifunctional device, featuring various measurement capabilities, with its primary measurement functions including:

Phase Meter Function— Verify the correctness of the main transformer differential protection and busbar differential protection.

Electrical Parameter Tester Features—Test the necessary parameters for the power system.

Metering Wiring Tester Features—Testing the three-phase three-wire electrical energy metering wiring connection;

Harmonic Content Test Function—Field-test the harmonic content of voltage and current.

Oscilloscope Functionality—Displaying a histogram as a simple oscilloscope to observe the waveform of test signals.
