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.

Dry Arc Resistance Tester
-
Dry Arc Resistance Tester is designed to conduct high voltage,low current Arc Resistance test on solid electrical insulation material as per:ASTM standard D495-99 (2004) and UL 746A. Why Arc Resistance Test? Many Cases of insulator failure are due to deterioration of its surface because of sustained electrical discharge or Arc. This test method is intended to test the resistance of insulating material when a high -Voltage low -current Arc close to the surface of insulation, intending to form a conducting path therein or in causing the material to become conducting due to decomposition and erosion.AdvantagesThis Test ensures that your products meet high standards of quality & safety. This product is meant for all Switchgears/ insulator/ Polymer/ electro plastic manufacturers and manufacturers who use insulators in their products e.g. Wiring Accessories, Appliances, HT/LT line insulators etc.

MULTI MEASURING INSTRUMENTS Co., Ltd.
The model MIS-PV1 is an insulation resistance tester for the exclusive use in photovoltaic systems. The ordinary insulation resistance testers cannot make measurement properly during generation of PV systems. This instrument, however, can measure the insulation resistance simply by touching probe to the live line whether making generation or not. There are two ranges of PVH and PVL. PVH is for high voltage generation system (more than 500V and less than 1000V) and PVL is for the system less than 500V.
