HD-2678 Water Cooled Generator Insulation Tester
Features
1.1 It features of microcomputer control, menu operation, large-screen LCD dot matrix display, low-voltage shielded method used for measurement and stable performance, and it is the intelligent instrument.
1.2 Automatic measuring range: R15, R60 and R600, and it can automatically calculate the absorption ratio and polarization index.
1.3 Testing voltage range: 5kV and 2.5kV, and it has the strong loading capacity. Between the winding and water collecting pipe, when the resistance is 100kΩ, the drop of testing voltage is less than 10%.
1.4 Measuring range: 0 to 200GΩ, and it can switch the range automatically.
1.5 It can automatically compensate and eliminate the influence on testing results by the polarization potential of water. When the resistance between the water collecting pipe and engine base is 3kΩ, the measuring accuracy can be guaranteed still.
1.6 The combination of simulation bar pointer and digital display can show the change trend of data and accurate measuring results, and show the water resistance.
1.7 The testing time can be displayed at any time, and the buzzer will automatically tweet for reminder at every 15 seconds.
1.8 After the completion of measuring, it will discharge the high voltage automatically, and the discharging time of high voltage is no more than 5 seconds.
1.9 It can measure the ambient temperature, air humidity and the date and time of each testing automatically.
1.10 It can save 60 groups of measuring results, and the data will not be lost for 20 years.
1.11 It has RS232 interface, therefore it can communicate with the computer data; it has printer, and therefore the measuring results can be printed, relieving the meter reading work.
1.12 It has the comprehensive perfect protection function, therefore the operational reliability is high.
