Product name: HCT3606 six-way differential protection wiring tester
Category: relay protection comprehensive test series

Detailed introduction

Product introduction

With the development of the power industry and the promotion and application of microcomputer integrated automation products, the correctness of the wiring of the protection circuit and the metering circuit directly affects two very important aspects of the power system. Since the wiring of the protection device and the high-voltage metering device is relatively large, it is easy to cause wrong wiring, but it is not easy to be detected (it is a complex wiring of differential protection. Sometimes the high and low sides are introduced at the same time, and there are different connection levels. It is very easy to connect wrongly, and it may not or refuse to operate during normal operation, which poses a great hidden danger). According to the needs of on-site testing, our company has developed a multi-functional vector analyzer in a timely manner.

Features

※ Three-way voltage and six-way current vectors are displayed on the same screen. For the test of differential protection devices, only one wiring is required to complete the drawing of the hexagonal vector diagram, which greatly improves work efficiency. In the case of small space and difficult wiring, the double clamp method can be used for multiple measurements to finally produce a complete hexagonal vector diagram in octal format;

※ Clamp-type current transformer wiring is used, and there is no need to disconnect the current loop, which is safe and convenient;

※ Vector analysis of complex protection devices can be performed to determine whether the wiring is correct, and the correct wiring diagram is given for comparison;

※ Conventional electrical parameter tests can be performed, and three-phase voltage, three-phase current, three-phase active power, three-phase apparent power, and three-phase phase angle can be displayed at the same time, and the voltage amplitude, current amplitude, and power values ​​converted to the primary side of the transformer can be directly read;

※ Three-phase three-wire high-voltage metering device error wiring inspection can be performed, and 48 types of three-phase three-wire wiring can be analyzed and judged, and the analysis results can be directly given to investigate and deal with malicious changes in metering wiring to steal electricity, effectively avoiding the loss of electricity bills;

※ It can perform harmonic analysis of the tested signal on site, analyze the contents of each harmonic from 2nd to 32nd order, and automatically calculate the total harmonic distortion;

※ Powered by large-capacity lithium battery, it can work continuously for up to 6 hours;

※ Users can save the test data in the form of records at any time for centralized management, filing, and review, and can store more than 2,000 sets of data;

※ The saved records can be uploaded to the background management computer for comprehensive analysis and review;

※ It has perpetual calendar and clock functions, and displays the date and time of the test work in real time;

※ A USB interface is reserved, and the instrument can be used to replace mobile storage devices such as USB flash drives.
