Megger  introduces the new 5 kV and 10 kV insulation resistance testers designed specifically for the testing and maintenance of high voltage electrical equipment.  

IEEE 43-2000 recommends the use of 10 kV for motor windings rated above 12 kV with the Megger S1-1052/2 insulation resistance testers facilitating this requirement.  

The insulation resistance testers feature a rugged construction. Made from tough polypropylene, the equipment is easy to carry and achieves an ingress protection rating of IP65.  

Key features of S1-552/2 and S1-1052/2 insulation resistance testers: 

  • Large easy-to-read backlit LCD display suitable for use in bright sunlight and poorly lit conditions
  • Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant
  • Elapsed time of the test is displayed constantly, removing the need for separate timers
  • Adjustable timers and limit alarms are included
  • Allows testing on mains power or internal rechargeable battery power
  • User-friendly controls with a quick start guide included in the lid of the instrument
  • Fitted with a guard terminal to enhance accuracy; guard test lead is included as standard
  • Increased flexibility with both models capable of setting the test voltage in steps from 50 V to the maximum output voltage
  • Designed to meet high safety standards and EN61010 requirements


  • CAT IV 600 V
  • Mains or battery powered
  • Digital/analogue backlit display
  • Variable test voltage from 50 to 5000 or 10,000 V
  • Automatic IR, PI, DAR, SV and DD tests
  • Measures to 15 TΩ (5 kV) and 35 TΩ (10 kV)
  • Charge current: 5 mA
  • RS232 and USB download of results to Megger Download Manager
  • On-board memory for results storage
