The Art of Rubblizing
Unlike other methods, including drop hammer methods, our resonant beam rubblizing fractures the slab at a low amplitude and high frequency on a shear plane 45 degree angle. Striking the pavement 44 times per second, at 2,000 lbs of pressure the concrete will be fractured throughout the entire slab including debonding the reinforcing steel while ...

Finite Element Analysis of High Frequency Breaker Vibrator
High-frequency breaker vibrator mainly includes three major components of the structure: the vibration box, knife row and bucket teeth. Due to the periodic impact load of the high-frequency breaker, there is a risk of failure if the structure of the exciter is not designed properly, which will seriously affect the working efficiency and service life of the breaker.

One of the most common high frequency applications is at 400 Hz. Figure 2 indicates the thermal rerating multiplier to be used with each circuit breaker family when applied on 400 Hz systems. At frequencies above 60 Hz, tests indicate that it takes more current to magnetically trip a circuit breaker than is required at 60 Hz. Figure 3 shows

These breakers can be tripped by noise, such as voltages induced by radio-frequency interference. Triac-based dimmers abruptly turn power on and off 120 times a second, causing switching noise which has high frequency components. "Mystery trippings" of GFCI's are not uncommon. To get to the root cause, you would need special equipment ...

Using VFDs on GFCI Devices
As a result, the Variable Frequency Drives (VFDs) industry is finding more instances of VFDs being powered from GFCIs. VFDs introduce high frequency harmonic content which may cause nuisance tripping on some GFCI devices. This paper is intended to assist anyone that needs to use a VFD on a circuit with GFCI protection.
