Our company is in accordance with the Standard Specification of electric power. Special launch of large capacity, high anti-interference, stable performance intelligent insulation resistance double display tester, the power equipment insulation, absorption ratio, polarization index test, provide accurate judgment of prophase series insulation test. Because the charge current will affect a large capacitive testing products for tested value, so we need large charging current. The charge ability is better, absorption ratio test value is more close to the true value. This instrument is short circuit current is greater than 3mA, to overcome the ordinary megger short-circuit current small, the test is not accurate, Susceptible to interference problems. The instrument adopts the real-time voltage and current sampling to do division, so in the process of testing, even if the voltage change, resistance of value calculated from Ohm's law is accurate. The instrument adopts the principle of combining digital and pointer, the multi gear output voltage, convenient use for old and new customers. Easy to carry, simple operation; with large capacity lithium ion rechargeable battery, AC-DC dual-use, and an undervoltage tip and the battery overcharge protection. The instrument can automatically display the current time, save 200 sets of test data and Storage time, for the test personnel's work provide a great convenience . This instrument is a new type of intelligent instrument, is the best choice for power test insulation detection.
1.a variety of voltage output options (2500V/5000V), (500V, 1000V, 2500V, 5000V), measuring resistance range up to 0 ~ 200GΩ, the resistance range can be automatically converted, and there is a corresponding indication. 2. The insulation resistance value is displayed synchronously in two ways. The mechanical pointer is made of ultra-thin wire structure and has strong seismic resistance. The use of the mechanical pointer makes it easy to observe the range of variation of the insulation resistance. The use of a dot-matrix liquid crystal screen can guide the user to operate the meter and accurately obtain the measurement result. 3. The mechanical head and the LCD screen are combined into one. Double scale display, automatic range conversion. Color scales are easy to read and have LEDs that display the corresponding colors. 4. Adopt embedded industrial single-chip microcomputer and real-time operating software system. With high degree of automation and strong anti-interference ability, the instrument can automatically calculate the absorption ratio and polarization index without manual intervention. 5. friendly operation interface, various measurement results have anti-power-down function, can continuously store 20 measurements. 6. When the meter generates high voltage, there is a prompt tone output. 7. Built-in residual high-voltage discharge circuit, the test can be completed to automatically discharge the residual high voltage on the device under test. 8. AC and DC, with rechargeable battery and AC adapter. 9. The instrument is portable and easy to operate in the field. 10.high-voltage short-circuit current ≥ 3mA, is an ideal test instrument for measuring insulation resistance of large transformers, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
