Product Description

MRT-20 20kV Insulation Resistance

Product Description

General Information
MRT-20 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-20 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

 

1. Covers IR/DAR/PI full-function test modes,  and realizes dual-mode calculation of DAR absorption ratio.
2. With simultaneous detection of leakage current Ix and absorption capacitance Cx,  and real-time acquisition and precise output of multi-dimensional parameters.
3. With wide measurement range and integrated automatic range switching function.
4. With short-circuit protection and residual voltage surge protection function.
5. Built-in high-voltage automatic discharge function, after the measurement is completed,  the object is automatically discharged to ensure safe operation.
6. With function for detecting whether the test object is energized before testing.Display the voltage in real time and provide audible and visual warnings to prevent accidental operation.
7. The high-voltage output can be continuously and smoothly adjusted from zero with high adjustment precision.
8. Integrate an automatic environmental parameter acquisition function,  which measures and records temperature,  humidity,  and test duration in real time.
9. Utilize digital signal processing technology,  it boasts outstanding anti-interference capabilities and is suitable for strong electromagnetic interference environment.
10. Support preset test duration; the system automatically stops the test after the set time is reached.
11. With intelligent timing function,  providing real-time updates on the testing process.
12. The system will automatically shut down after 5 minutes of inactivity.
13. Support historical data querying,  retrieval,  and management,  utilizing non-volatile storage technology.
14. With RS232 communication interface.
15. The human-machine interface that displays measurement results and data trends in real time with high accuracy.
16. With the shockproof,  moisture-proof,  and dustproof sealed design.
