Product Details

High Voltage Circuit Breaker Characteristic Tester Instrument Features

◆Strong anti-interference capability, fully adaptable to on-site testing at high-voltage substations.

◆High-grade safety case integrated chassis, preventing possible damage during transportation and use.

◆3x4 channels for time measurement, with independent channel timing and time resolution up to 0.05ms. 6 digital channels for measurement, and 6 digital/analog (with closing resistor) channels with automatic identification.

◆Full Chinese operation interface, wide-temperature semi-transmissive LCD display, real-time display of all contact states.

◆Patented dynamic key attribute design and interface layout, making human-machine interaction simple, clear, and efficient.

◆The instrument automatically identifies the target close/open state and selects the corresponding test mode, making operation simple and convenient.

◆The instrument comes with an adjustable operating power supply from 20A, 20V to 280V, with low ripple factor; only 220V AC is needed on-site for various tests.

◆The instrument provides energy storage function for the switch through its internal DC operating power supply.

◆Supports external power input; when the 20A power supply is insufficient for on-site needs, an external DC operating power supply can be connected, and the internal power supply automatically shuts off.

◆Fully automatic low-voltage test; only need to set the starting voltage value, and the test process can be completed without manual intervention.

◆High-speed thermal printer for quick storage of test results.

◆Real-time wiring error check function to prevent user wiring errors that could damage the instrument or the device under test.

◆Reclosing test can measure metal short-circuit and no-current time in one go.

◆Supports linear and angular velocity measurement, suitable for vacuum, low-oil, multi-oil, SF6, load, GIS, etc., from 6KV to 750KV.

◆Dynamic parameter testing of switches, with test results available for in-depth analysis.

◆Automatic identification and switching between internal and external synchronization, supporting time testing of AC load switches.

◆Stores 16 sets of measurement data and waveforms locally; unlimited storage when a USB drive is connected, with optional automatic USB storage function.

◆Provides LAN connection to PC; optional professional PC analysis software for precise analysis of test data.

◆Excellent electromagnetic compatibility design ensures stable operation in substations of 500kV and above; wiring short-circuit protection and robust output arc suppression design ensure equipment and personnel safety under abnormal conditions.
