I. XHRM-10KK Strong anti-jamming Insulation resistance tester is a compact, high voltage output, battery powered testing instrument, can be used to measure the absorption ratio, polarization index insulation resistance test items.
This insulation resistance tester is designed and developed to solve the electrical insulation quality evaluation of large-scale high-voltage transformers, motors, generators, long-distance power cables, tubular busbars, etc. under the strong interference of high-voltage substations and power plants. With multi-level output voltage, large short-circuit current, real-time voltage monitoring, leakage current display, automatic timing, automatic discharge and other functions, it is especially suitable for large capacitive test products and test sites with large power frequency induced voltage. Large-screen digital Type/analog display, can automatically measure and memorize R15S, R60S, R10min values, and automatically display polarization index (PI), absorption ratio (DAR) test values and test time.
The instrument cooperates with the electrostatic induction voltage suppressor to solve the problem of insulation resistance test and phase verification on both sides of the line when the power frequency induced voltage on the line under test is not greater than 20kV and below in the high-voltage transmission line parameter test work.
II.Main Features
2.1 Large screen display, output voltage 0.5kV, 1kV, 2.5kV, 5kV, 10kV can be
Setting, the instrument will not be burned out under short-circuit state, the short-circuit current is ≥10mA, the actual output test voltage, and the real-time leakage current are displayed on the same screen in real time.
2.2 The analog pointer and the digital display are displayed on the same screen. The digital reflects the accuracy of the insulation resistance of the tested product, and the analog pointer can reflect the dynamic change of the insulation resistance during the test.
2.3 It has the functions of actual test product applied voltage measurement, leakage current measurement, automatic discharge, etc., through the actual test product applied voltage measurement function, it can intuitively display the load after the test
Whether the meter drop voltage meets the standard requirements.
2.4 It can automatically measure and memorize the values of R15S, R60S and R10min, and automatically display the test values and test time of polarization index (PI), absorption ratio (DAR).
2.5 Automatic discharge: Use advanced high-voltage discharge technology to quickly discharge the capacitive test product, and measure the discharge voltage in real time during discharge (the test voltage of the test product reaches 0V). For large capacitive test products, due to the presence of dielectric absorption charges, manual discharge is required to ensure Personnel safety.
2.6 Intelligent battery charging management, which can effectively prevent battery life shortening or damage caused by battery overcharging, digital display of battery power and undervoltage alarm protection, internal rechargeable lithium battery or external AC power supply, true AC and DC dual use does not affect test accuracy.
2.7 Alarm function when boosting voltage, when the device has a high-voltage output, the buzzer has a warning function, indicating that there is a high-voltage output at this time.
2.8 Automatic shutdown function: The instrument has an automatic shutdown function, and it will automatically shut down after 5 minutes after the measurement.
