상품 상세보기 : 저항측정기 Ohm Meters - MG817004 5KV Insulation Resistance Tester

The Megger BM11D and BM21 5 kV Insulation Resistance Testers are portable, battery-powered

The Megger BM11D and BM21 5 kV Insulation Resistance Testers are portable, battery-powered, high-voltage instruments that use the latest electronic design and technology. The instruments have user-friendly keypads with push-buttons to select test voltages of 500, 1000, 2500, and 5000 V dc. In addition to the standard test voltages, a variable voltage feature on the BM21 selects test voltages between 25 and 5000 V dc in 25-V steps.

Features

Analog/digital display
Multiple test voltages
Integral timer
Automatic discharge of equipment under test
Comprehensive battery state indicator

Applications

High-voltage power cables
Large motor/generator windings
Line and substation transformers
High-voltage buses
