General information about AD4006B intelligent insulation resistance tester
AD4006B intelligent insulation resistance tester is newly designed based on AD4006B. It can conduct digital insulation test, and its highest testing voltage can be up to 10kv. It is widely applied for the maintenance of substation and power station. AD4006B is suitable to measure IR(insulation resistance), AR(absorption ratio) and PI(polarity index) of various HV equipment, such as switchgear, transformer, reactor, capacitor, generator and cable.
Features:
Adopt digital process technology, with strong anti-interference ability and can do measurement under strong electromagnetic interference condition
Large volume, can meet the requirements of HV, high resistance and big load testing;
With quake-proof, damp-proof and dust-proof structure, can adjust to bad working condition;
Friendly and beautiful interface, testing results and data variation trend can be displayed accurately.
Perfect protection functions, can withstand short circuit and the surge of tested capacitor residual voltage.
Max. measuring range can be up to 10TΩ, and range can be converted automatically;
HV at each gear is adjustable from zero continuously;
Measure R15、R60、R600, and calculate absorption ratio & polarity index automatically’
Measure environment temperature, air humidity and time automatically;
Display testing time, buzz every 15s, and will prompt to turn off without operation for 5mins.
After testing, it can leak HV automatically, and leakage time is less than 30S
Store 60 sets of testing results, and data can be kept for 20 years.
With RS232 serial interface, can communicate with computer;
