Product Details

High Voltage Switch Characteristic Tester Instrument Features

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

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

◆3x4 channels for time measurement, independent channel timing, time resolution up to 0.05ms. 6 digital channels for measurement, 6 digital/analog (with closing resistor) channels auto-detected for testing.

◆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, efficient, and quick.

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

◆Built-in 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 via 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 completes without manual intervention.

◆High-speed thermal printer, test results quickly stored.

◆Real-time wiring error detection function to prevent user misconnection from damaging 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, test results can be deeply analyzed.

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

◆Stores 16 sets of measurement data and waveforms internally; unlimited storage when USB is connected, optional USB auto-save function.

◆Provides LAN connection to PC; optional PC professional analysis software can precisely analyze test data.

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