Product introduction
Insulation resistance in proportion to the pressing time during the testing of the large capacity power equipment, longer pressing time maks higher insulation resistance. This phenomenon called absorption phenomenon of insulation. To understand the insulation performance of the test product, firstly, must do its absorption ratio and polarization index test for the next leak , dielectric loss , partial discharge , etc., insulation performance tests to provide security. Nanao Electric Wuhan Electric Co., Ltd. in accordance with standardized protocols special launch NA501 Power Smart insulation resistance tester ( hereinafter referred to as NA501), for electrical equipment for insulation, absorption ratio, polarization index test, insulation test for the series provide an initial accurate judgments.
Also called name
Intelligent Insulation resistance tester, insulation resistance tester intelligent, insulation resistance tester, insulation resistance tester
The Characteristics of the products
1 This instrument uses advanced MCU control processes, human-machine interface dialogue, easy to carry, easy to operate; enclosed battery, AC-DC, and has under-voltage protection and battery overcharge protection. The instrument can automatically display the current time, save 8 group of historical test data and time for the trial to provide a great convenience.
2.NA501 short-circuit current is more than 3mA, to overcome the common type megger short circuit current is small, the test is not accurate, vulnerable to interference and other defects.
3.NA501 do division by sampling voltage and current timely, this way ensuring the accuracy of the resistance value not influence by the unstable voltage during the test process.
