10KV HV Withstand Insulation Resistance Tester

Overview:

  Goldhome is a high-tech company specializing in the production of high-voltage insulation resistance testers, adhering to the principle of putting customers first.

  The HM2306 is an advanced portable instrument designed specifically for accurate and reliable measurement of the insulation resistance of high-voltage electrical equipment. It serves as an important tool in power supply systems for predictive maintenance, commissioning, and troubleshooting.

  Application Areas: The insulation resistance tester addresses the assessment and design of electrical insulation quality for large high-voltage transformers, electric motors, generators, long power cables, tubular busbars, and other equipment in high-voltage substations and power plant sites with strong interference. Featuring high power output, real-time voltage measurement (actual charged voltage), leakage current measurement, and automatic discharge (discharge voltage measurement). It is particularly suitable for testing large capacitive equipment and in 110kV power interference test sites.

●Designed in strict compliance with safety standards, output voltage: 500V, 1000V, 2500V, 5000V, 10kV, 12kV, 15kV.
●AC 2000V, 50mA induction current capable of withstanding harsh testing environments.
●5.7" large screen display showing actual test voltage and leakage current.
●Capacitance measurement function.
●Short circuit current ≥10mA.
●Automatic calibration function ensures instrument accuracy prior to testing.
●This instrument features live voltage measurement, leakage current measurement, and automatic discharge for actual samples. Its live voltage measurement function allows direct verification of whether the sag voltage of the loaded test instrument meets national standards. Additionally, the insulation condition of the sample can be directly assessed through its live voltage and leakage current measurement functions.
● It automatically measures and stores R15S, R60S, and R10min values, displaying polarization index (PI), diurnal absorption ratio (DAR) test results, and test duration.
● Exceptional anti-interference performance, particularly suited for 110kV and higher voltage power systems with large-capacity transformers and long-distance power cables.
Internal rechargeable lithium battery power supply or ac power supply, real ac and dc dual-use does not affect the test accuracy.
●The analog pointer coexists with the digital display, and the number reflects the accuracy of the insulation resistance of the tested product, and the analog pointer can reflect the dynamic change of insulation resistance during the test process.
●Alarm function during voltage boost. The buzzer has alarm function when the device has high voltage output, indicating that there is high voltage output.
●Battery quantity digital display and under voltage alarm protection function.
●Intelligent battery charging management can effectively prevent battery life shortening or damage caused by overcharging.
●Automatic shutdown function: this instrument has automatic shutdown function. It will shut down automatically 10 minutes after the End of measurement.

III.Function Description: 

 

1.voltage selection interface

Voltage selection interface, in the rated voltage selection interface. Voltage gears are 500V, 1kV, 2.5kv, 5kV,10kV ,12kVand 15kV respectively. Select the rated voltage with the "Voltage choose"key.

 

2.interface before test

For the pre-test interface. Battery status and measurement status "WAIT" are displayed in the system information. In the test main interface, "Voltage choose" represents the voltage selected according to the requirements of the test subject, "Vt" represents the real-time voltage of the port, and "It" represents the real-time leakage current of the test subject. R15s represents the resistance value at 15s, R1m represents the resistance value at 1 minute, and R10m represents the resistance value at 10 minutes. At this time, it is in the state of waiting for measurement, and the appropriate voltage can be selected as required.

3.shows the interface under test.

The system indicates that the high voltage is on, the instrument starts to measure the insulation resistance, and the measurement status shows "START". Start timing (00 mins: 00 seconds). A timing cycle is 10 minutes 00 seconds. When the cycle meter is full, it will automatically flip and start timing again from 00 minutes, 00 seconds. Testing, insulation resistance, real-time clock, R15s resistance, R1m (1 minute) resistance, and R10m (10 minutes) resistance shown in testing main interface left half, set voltage, port, battery voltage, the measured voltage, temperature and humidity absorption ratio, polarization index, real-time leakage current and the instrument work status display to the testing main interface right half, See figure 3..

When the high voltage measurement is started, the buzzer will sound an alarm. The characteristic parameters in the measurement process, such as R15s, R1m, R10m, absorption ratio K (K=R60s/R15s) and polarization index PI (PI=R10m/R1m), will be displayed in the main interface of the test in sequence. Press "Start up/stop"to End measurement. (press one time to start high voltage measurement and then press another time to stop measurement in default setting)
