Description click to view larger image AEMC 6550 10 kV and 6555 15 kV Megohmmeters The Megohmmeter Models 6550 and 6555 are expert tools for testing insulation safely and accurately and ideal for use on rotating equipment and machinery operating at 10kV or higher. They are the only fully automated 10,000V and 15,000V graphical insulation testers. They provide insulation measurements up to 30,000GΩ (30TΩ). Test results include DAR, PI, DD, ΔR, Capacitance, Leakage Current, as well as programmable temperature correction of resistance readings. Models 6550 & 6555 also offer the ability to program up to three step voltage profiles (from 40 to 10,000 or 15,000V – model dependent), each containing up to ten steps. They also include three ramp profiles and three programmable test voltages in addition to the standard fixed voltages of 500, 1000, 2500, 5000, 10,000 and 15,000V. These units have a USB interface and a data storage function, which permits the storage of test results in files specific to the device under test. The included DataView® software configures and runs tests directly from a PC and creates data analysis reports. Features Detection and measurement of input voltage, frequency, and current prior to running a test Measurements at a fixed test voltage of 500, 1000, 2500, 5000, 10,000VDC (15,000VDC model 5655) Ramp voltage measurements with a ramp from 40 to 1100V (500 to 15,000V model 5655) Non-destructive (Early break) test, test stopped at a preset current (Break at I-limit) or Burn mode with no predefined stop point Digital filtering of insulation measurements Live measurement of the voltage to warn the operator of potential unsafe conditions Programmable thresholds to trigger audible Timed measurement duration checks Fuse protection with display indication of defective fuse condition Stores up to 80,000 measurements Optically-isolated USB communication for transfer onto PC and and report generation with the included DataView® software Applications Acceptance testing and preventive maintenance Test motors, pumps, valves, cables, switchgears and electrical wiring installations Continuity checks High resistance or absorption tests Spot reading tests Timed resistance measurements Dielectric Absorption Ratio (DAR) and Polarization Index (PI) tests Multi-layer insulation testing (DD) Test old or water damaged installations over long time periods Motor insulation resistance measurement AEMC-6550-6555-DataSheet
