Quick and Easy Insulation Testing with the BM15 and MJ15 Megger Tester

  • Uncategorized

The constant weathering, electrical and thermal stress accelerates the degradation of insulators in various electrical components. Insulators are designed to withstand extreme stress and rough conditions. However, after a while of operation, insulators tend to develop defects and may eventually fail. It would be best to find defects that are just about to start because this reduces the hassle of service interruption due to unexpected failures. Preventive maintenance also allows you to schedule the replacement of electrical components efficiently. 

To help you test for insulation reliability, check out the insulation testers from Megger. These devices have an output test voltage of 5 kiloVolts. These Megger testers comply with the IEC1010 safety specification, EMC and CE. They also have a unique scale overlay that gives a pass or fail result. Here is a quick comparison of the features to help you decide which tester suits you best.

Megger BM15 Insulation Meter

The BM15 is a compact and simple to use tester that allows quick testing of insulation. It provides a pass or fail test which makes it suitable for less experienced technicians. This allows a quick decision to be made during diagnostics.

Features

  •        Rugged case to tolerate rough handling
  •        Resilient analog scale
  •        Single scale to reduce operator error
  •        Resistance range from 100 kΩ to 20 GΩ
  •        Variable test voltage of 500 V, 1000 V, 2500 V and 5000 V
  •        Maximum capacitance load of 5 μF
  •        Interference suppression at 1 mA rms at 50/60 Hz
  •        Discharge resistance of <500 kΩ
  •        Can measure voltage from 0 to 600 Volts
  •        720 V AC/DC overload rating
  •        CAT III 300 V phase to earth or CAT I 600 V rating
  •        Battery Powered

Megger MJ15 Insulation Meter

The MJ15 has almost identical features with the BM15 but has a dual power supply option. The device can be powered through batteries or through its built-in hand-cranked generator. This makes it suitable for long use on the field. Even if you run out of batteries or have no access to AC Mains, you can still carry out tests.
