MRT-10 Insulation Resistance
Product Description
General Information
MRT-10 Insulation Resistance Tester has perfect testing function of various insulation resistance parameters and excellent anti-interference ability, which can be used to test the insulation resistance of large capacity high voltage electrical equipment and transmission lines in strong inductive environment such as substation.
MRT-10 has a wide range, high resolution, convenient operation, sturdiness and durability, accuracy and reliability, stable performance, and strong anti-interference ability. The instrument has insulation resistance test (IR); polarization index test (PI); absorption ratio test (DAR); Dielectric discharge rate DD, step voltage SV test functions.
Features
- The fully isolated power supply design is adopted to achieve effective electrical isolation between high and low voltage circuits. The isolation voltage is as high as 25kV, which effectively ensures the safety of operators.
- The full touch 7-inch capacitive screen plus one-key shuttle function, the brightness reaches 400cd/m2, and the operation is more convenient.
- 7 voltage ranges: 100V, 250V, 500V, 1000V, 2500V, 5000V, 10000V. Custom voltage mode 50V~10000V continuously adjustable, step voltage 10V.
- Maximum output short-circuit current 6mA; and 1mA, 2mA, 3mA, 4mA, 5mA, 6mA adjustable.
- The maximum continuous output power is 55W.
- With an independent discharge circuit, which can quickly discharge the test product after the test is completed.
- With the function of test product breakdown protection and arc burning; it can continuously operate in the breakdown arc burning state to accurately locate the position of the insulation weak point.
- With the test functions of insulation resistance IR, absorption ratio DAR, polarization index PI, dielectric discharge rate DD, and step voltage SV.
- Supports two DAR absorption ratio calculation modes: R600s/R30s and R600s/R15s.
- With DC and AC voltmeter functions, automatically identifies DC voltage and AC voltage signals, and can measure the frequency of AC voltage signals.
- With the function of measuring cable length and is equipped with controllable hardware and software filters, which significantly improves the anti-interference performance.
- The curve display and recording of insulation resistance, voltage, and current over time help testers quickly evaluate the insulation condition of the test product.
- With USB storage function, which is convenient for batch export of test data to USB flash drive.
- It has various communication interfaces and supports RS232 (optional RS485) and Bluetooth communication.
- Built-in large-capacity lithium battery and fast charger, and the instrument panel and LCD screen display the charging status in real time.
