OEM Best Contact Resistance Tester Manufacturers – GDSL-A Automatic 3-phase Primary Current Injection Test Set with Temperature Test – HV Hipot

Features

● Built-in high configuration industrial control computer, the programmable logic controller (PLC) as the central processor, real-time scan of AC signal, to achieve comprehensive monitoring and closed-loop control, and design password settings management, only the personnel who gets corresponding operation authority, can carry out operation of certain functions.
● Color LCD touch screen. Using intelligent sensor based on field bus technology and realize the full digital data transmission, display operation unit is touch type color LCD screen, full English menu, the interface is clear and intuitive, the operation is simple and convenient. Test without any auxiliary equipment, automatic control, fast, simple and convenient.
● Automatic and manual test mode, with automatic constant-current system.
● No need manual monitoring, only need to set test, current and step length, save tedious labor such as manual voltage regulator, artificial records and curve sketching, etc.. to reduce labor intensity, improve work efficiency, read data to a computer for checking after work.
● Automatic alarm function when exceeding the limit value, self protection function of over heating, over current, over voltage and short circuit. The protection of AC voltage regulator uses the dual protection of microcomputer automatic protection control and mechanical micro motion limit switch, to ensure the normal operation of the constant current power supply, and improve the safety and reliability of the products.
● Humanized interface, friendly interface, full English operation interface, control software have a variety of practical functions, such as data record, current & temperature waveform storage, data management, reports, printing and so on; parameter setting is completed in the software. A more intuitive analysis of the relationship between current and temperature. During the test, automatic tracking of the target current, automatic stable output current, automatic adjusting of the three-phase current; after the test is completed, it will return to zero position automatically.
● Automatically adjust the AC constant current source to meet the temperature rise test of LV and medium switchgear (Control cabinet with multiple outputs, such as GCK, MNS, etc.)
● With a three-phase automatic balance system to ensure that the three-phase balanced output, the output current sampling using 0.2% level high precision current transformer.
● With precision adjustment menu, the user can adjust the error value by self. Programmable AC constant current power supply can realize intelligent calibration, automatic generation of multi segment calibration coefficients in the adjustable range of equipment, to ensure the stabilized current accuracy of constant current power supply.
● Three phase full current curve and 16 path temperature curve can be displayed.
● Test module can be customized according to the user requirements, software lifetime free upgrades.

Functions

● It has zero protection function to prevent the impact of large current from causing damage to the sample. It cannot be started when it is not at zero position.
● Impact selection function, when the circuit breaker quick-break test is performed, the zero protection function can be cut off and the required current value can be directly output.
● Output current mode: The true RMS value is continuously adjustable.
● The output current is a standard sine wave, and the waveform distortion rate is less than 5%.
● Voltage and current display adopts new high-precision LED digital display
● Switchable size current range to improve display fineness for more accurate readings.
● The power supply voltage and regulator output voltage can be switched to display for easy viewing.
● The equipment capacity is designed for short-term, intermittent work in 5 minutes.
● For batch testing, close for 10 minutes after 2.5 minutes of continuous operation.
● It can measure the current action time of the tested component and record the lock action time synchronously. (optional)
● Measured time range: 0.001S～999.999S Resolution 1ms, measurement error: 0.005% range ± 2digs. (optional)
● The test value of primary current and secondary current can be directly displayed to facilitate the transformer ratio test. (optional)
● Secondary current range 0~5A resolution 1mA (optional)
● If the temperature rise (30 minutes – 24 hours) should be customized according to the long-term work temperature rise. (optional)
● Can be customized three-phase with balance adjustment riser (optional)
● Can be customized AC and DC riser (optional
