The Megger® BM11 series of 5 kV Insulation Testers provides a choice
of features to suit all applications and budgets.
The traditional BM11 instrument became the industry-standard 5 kV tester. It is battery-powered, housed in a rugged case and has a large, simple white-on-black scale. The series has been extended with three analog/digital instruments; the BM11D, BM21 and BM25. These instruments show results and test options on a large, clear analog/digital scale for both practicality and precision. A built-in timer makes both spot tests and PI testing easier to carry out. They are powered by a built-in rechargeable lead-acid battery which can be charged directly from any supply from 95 V to 265 V. All testers incorporate a guard terminal to allow surface leakage to be removed. Pre-set standard test voltages at 500 V, 1000 V, 2500 V and 5000 V are supplemented on the BM21 and BM25 unit switch a variable test voltage in 25 V steps. These top of the range units also allow measurement of resistance to 5 TΩ,leakage current to 0,01 nA and can display capacitance at the end of a test to 10 µF. The BM25 extends the diagnostic testing capability of the range by performing automatic Polarization Index, Step-Voltage and Dielectric Discharge tests as well as providing an optically isolated RS232 port for downloading results during a test. |
