Kusam Electrical Industries Limited
• The KM 6213A IN is the KUSAM-MECO premium model of High Voltage Digital Insulation Resistance Testers.• The KM 6213A IN has new added features with a low consumption High Performance processor.• It displays results much faster and has more advanced features.• The KM 6213A IN has Automatic Polarization Index and Dielectric Absorption Ratio Calculations.• Results are displayed on the new High Contrast LCD. It’s mounting angle makes it more readable for all users, in different working conditions.• The user’s manual reflects the new features and added benefits of this instrument.• It has Auto-Off, Auto-Stop, EnerSave™ and is a non destructive tester.• Once you start the tester, it waits for your selection. You can go up and down in voltage to select the voltage at which you want to test the insulation. Once you have selected that voltage, you need to connect the test leads to the Insulation Tester to measure. Then it measures voltage to ensure there is no voltage present on the equipment under test. If there is a voltage present, it will warn you to disconnect the circuit before proceeding. If it’s free of any voltage, then you can proceed with the testing. This ensures that no damage is done to the Insulation Tester KM 6213AIN.• One of the new innovation on this tester is also the way the new unique calibration process works. It’s fully digital, has no moving parts and does not require expensive and complicated jigs or computers systems to be calibrated. It’s cheaper to maintain than any other Digital HV Insulation tester on the market today. The KM 6213AIN is supplied standard with our Premium test Leads Kit, the AL-50.

Single-Phase Transformer Winding Resistance Meters
RMO-TW Series
-
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test. Finally, a user can export all results in the form of a report.
