Megger Baker Instruments

Megger Baker Instruments is a division of global electrical test equipment company Megger. Baker Instruments has a long legacy as a manufacturer of electrical test equipment for motors and generators, ranging from portable devices which test insulation and circuit condition to permanently-installed solutions for monitoring many motors in a facility. Baker’s products fall into two categories: static (off-line testing) and dynamic (on-line testing). Our static testers provide a comprehensive range of standards-compliant tests, including low voltage and high voltage testing, which can expose weaknesses in winding insulation long before an actual failure, leading to predictive maintenance support as well as troubleshooting and QC in a motor repair/rewind context. Dynamic testers monitor the motor’s electrical parameters in real time, allowing users to identify issues with the power supply, the motor itself or its loading conditions. Baker Instruments also offers QC systems for motor OEMs in a production environment, and systems for testing DC traction motors. Sales and training are based in Fort Collins, Colorado, USA.

Application list: 

  • Cable testing
  • Circuit breaker testing
  • PAT testing
  • Relay and protection testing

What You Didn’t Know About Surge Testing

Scott Lebruska from Megger explains why unless a surge test is implemented, this critical winding insulation problem can’t be detected until it reaches the groundwall insulation due to extreme heat advanced by shorted turns: too late!  Find out how the surge test works, why megohm or hipot testing will not detect winding insulation problems, and why this fantastic nondestructive test has standards that your predictive maintenance program needs to employ.
