Product Function
Suitable for insulation resistance testing of large-scale electrical equipment and transmission lines in large-capacity, high-voltage, and strong-inductive environments. The tester provides comprehensive measurement functions including insulation resistance test (IR), polarization index test (PI), dielectric absorption ratio test (DAR), step test (STEP), ramp test (RAMP), dielectric discharge index test (DD), AC/DC voltage test (V), and distributed capacitance test (CAP).
Product Features
1.Touch color screen: all test data displayed on the same screen. Test operation and historical record viewing are very convenient.
2.Unique strong anti-interference technology ensures stable testing capability in large distributed capacitance sites (e.g., long cables) and strong electromagnetic interference environments (e.g., substations).
3.Comprehensive measurement functions: insulation resistance (IR), polarization index (PI), dielectric absorption ratio (DAR), step (STEP), ramp (RAMP), dielectric discharge index (DD), distributed capacitance (CAP), AC/DC voltage (V).
4.Customizable measurement mode: selectable PI and DAR calculation formulas, adjustable test voltage and test duration, providing multiple options for special site requirements.
5.Voltage monitor: automatically monitors the live voltage of the tested object. If the voltage exceeds 36V, the test is automatically prohibited to protect the instrument and the operator.
6.Current monitor: automatically displays the test circuit current.
7.Temperature monitor: automatically displays the temperature and humidity inside the tester.
8.Automatic discharge function: automatically and quickly releases the charge of the tested object after the test, no external discharge circuit required.
9.Large capacity test record memory: automatically stores up to 1000 sets of real time test data with test date and time.
10.USB communication: uploads recorded data to a computer for storage and statistical analysis.
11.Bluetooth communication: uploads test results to a mobile phone.
