Unless your background is in ac power, it’s possible you haven’t run into the term triplen harmonic. Triplen harmonics have to do with the third harmonic. Even-numbered harmonics do not normally exist in power systems due to symmetry between the positive and negative halves of the ac cycle. It is the odd-numbered harmonics that engineers […]

Audio measurement software supports GRAS SysCheck2-capable mics
The latest update to APx500 audio measurement software, version 7.0, adds new enhancements suited to a wide range of audio test applications, whether analog, digital, or acoustic. Developed by GRAS Sound & Vibration, also part of Axiometrix Solutions, SysCheck2 is a system designed to actively verify whether the sensitivity of a microphone has drifted since […]
DC nanoammeter measures from 1 nA to 800 mA with 10-pA resolution
The NanoRanger NR-01 is an affordable, highly accurate 3.5-digit dc ammeter designed for accurately measuring low currents. With automatic dynamic ranging (9 ranges across 8.5 decades), NanoRanger measures currents from 1 nA up to 800 mA with a maximum resolution of 10 pA. Each instrument is supplied factory calibrated, eliminating the requirement for high-cost precision […]
Ethernet tester includes 5 GHz WLAN support
The NetXpert XG2 Ethernet tester offers many of the same benefits and capabilities as the flagship NetXpert XG with the addition of several new hardware features, including 5GHz wireless local-area network (WLAN) support. Like the NetXpert XG, the NetXpert XG2 performs Bit Error Rate Tests (BERT) from 100 megabytes (MB) to 10 Gb regardless of […]
Tester handles all-in-one LMR, PMR and LTE radio testing
The CX300 ComXpert is a comprehensive communications test and alignment solution in an easy-to-use, ruggedized form factor. The CX300 is the first LTE-ready radio test set equipped to test both radio and broadband network infrastructure, helping today’s radio technicians ensure complete communications coverage. As the global public safety radio market rapidly transitions from analog to […]
Don’t touch that! Things they don’t teach you in circuits lab
The domain of most electronics engineers these days is confined to voltage levels ranging from microvolts on up to a few hundred volts. But when electronic equipment fails or there’s a problem with facility wiring, these same engineers may, in a pinch, be called upon to do basic troubleshooting of power levels far beyond their […]
Grounding considerations for renewable power generation
It pays to know the difficulties that can arise when testing and evaluating ground systems for solar panel arrays and wind farms. Jeff Jowett, Megger Industrial wind turbines are typically 280 ft high and getting taller. Their height makes them prime targets for lightning strokes that peak in less than 10 µsec while producing tens […]
Looking for ghostly goings-on with a milligauss meter
Tune in to TV shows that are purportedly about ghost hunting and you’ll often see people wandering around in the dark with an instrument called a milligauss meter. A milligauss meter detects changing magnetic fields. (It won’t detect static fields as from a bar magnet.) When a milligauss meter shows a reading during a ghosting […]
