- Commodity name: ZEC-702C three-phase relay protection tester
The standard 4-phase voltage 3-phase current output has a 4-phase voltage 3-phase current output, which can be easily combined for various types of protection tests. Each phase voltage can output 120V, current three can output 120A, the fourth phase voltage Ux is a multi-function voltage item, which can be set to 4 kinds of 3U0 or check the same period voltage, or any certain voltage value.

1. main features:

• The standard 4-phase voltage 3-phase current output has a 4-phase voltage 3-phase current output, which can be easily combined for various types of protection tests. Each phase voltage can output 120V, current three can output 120A, the fourth phase voltage Ux is a multi-function voltage item, which can be set to 4 kinds of 3U0 or check the same period voltage, or any certain voltage value.

• stand-alone convenient operation stand-alone by a convenient and flexible rotating mouse through the large LCD screen operation, all Chinese display. Can complete most of the field test verification work, can be a variety of relay and microcomputer protection verification, and can simulate a variety of complex transient, permanent, conversion fault for the whole group of tests. Boot can be used, easy to operate.

Dual operation mode, connecting the computer to run through the full set of Chinese operation software on the Windows platform, can carry out various large-scale complex and more automated verification work, can easily test and scan various protection setting values, can store test data in real time, display vector diagrams, draw fault waveforms, print reports online, etc.

The software has powerful functions and can complete various large-scale and complex verification work with high degree of automation, such as three-phase differential test, quick switching of auxiliary power supply, automatic switching test for standby, reclosing of line protection inspection at the same time, etc. It can conveniently test and scan various protection fixed values, replay faults, store test data in real time, display vector diagrams, print reports online, etc.

The switch contact rich relay protection tester has 8 contact inputs and 4 pairs of empty contact outputs. The input contact is compatible with the empty contact and the potential contact of 0~250V, and can be recognized automatically and intelligently. Input and output contacts can be expanded according to user needs.

Large-screen LCD display This machine adopts 320 × 240 dot matrix large-screen high-resolution graphic LCD display. All operation processes are set on the display screen. The operation interface and test results are displayed in Chinese, and the display is intuitive and clear.

• Self-protection adopts a reasonably designed heat dissipation structure, and has a variety of reliable and perfect protection measures and power soft start, and certain fault self-diagnosis and locking functions.

• With independent dedicated DC power output device with a 110V and 220V dedicated adjustable DC power output.

• High cost performance is a cross-professional joint design products, integrated multi-professional advanced scientific and technological achievements. Both the performance of a large tester, and the price of a small tester, with a high performance-price ratio.
