A permanently installed absence of voltage tester (AVT) may include a connectivity verification system for verifying the connectivity of system cable leads to the main power lines in electrical equipment. An installed AVT may indicate whether the electrical equipment is in an electrically safe state without first requiring direct access to the equipment. One step in the AVT test procedure may include connectivity verification by the connectivity verification system, which may include a sub-procedure to confirm that the installed AVT is directly coupled as intended with direct connection to the equipment being monitored. The connectivity verification system may validate that the AVT is measuring the actual voltage on the power lines of the electrical equipment and has not registered a no-voltage condition due to an unknown disconnection error or installation failure.

Connectivity verification for an absence of voltage tester system

An absence of voltage indicator has an isolation circuit, an FM modulator attached to the isolation circuit, a reference oscillator, and a mixer attached to the reference oscillator and the FM modulator, wherein the output of the mixer is the difference of the two signals. In one embodiment, the FM modulator includes a variable capacitor which varies in response to a voltage in parallel to a fixed capacitor and an inductor in parallel to the capacitors.

Absence of voltage detector

A high voltage pulse power delivery system is provided that includes dedicated safety features including fault detection and fault management. Alongside normal communications cabling, the pulse power delivery system provides remote power over standard multi-conductor cabling without dedicated conduit or separation. This simplifies installation of equipment, increases overall speed of deployment, and significantly reduces cost for deployment. The pulse power delivery system is further configured to transport power through a pulse current waveform.

Systems, apparatuses, and methods for pulse shaping in high voltage power systems

A method of detecting a fault in a power distribution system includes placing a signal on the system at a frequency Fand then detecting a change in the signal due to a change in the impedence of the system as a result of a fault wherein the change is one of a change in phase, a change in signal tone, or a change in voltage level at the load. In one embodiment, band reject filters can be used to diminish the signal at the load or source. In another embodiment, the power source can be a periodic pulsed power source and the signal can be placed on the system during an idle phase of the periodic pulsed power.

Method of detecting a fault in a pulsed power distribution system

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

Communication cable including a mosaic tape

A system for the verification of the absence of voltage has a first series of resistors and a first voltage limiter connected between a power line and a first voltage sensor and such as to limit a sensed voltage to a set amount above a threshold set by a standard and a first series of LC resonance filters connected between the power line and a RF signal generator. The system also has a second series of resistors and a second voltage limiter connected between the power line and a second voltage sensor and a second series of LC resonance filters connected between the power line and an RF signal detector. The system is configured to detect continuity to the voltage line by sending an RF signal generated by the RF signal generator through the first lead line and detecting it at the RF signal detector via the second lead line.

Absence of voltage detection device for medium voltage application

A system and method for detecting the connectivity of an absence of voltage detector to the source of power to be detected has a first terminal wire connected to a first terminal and a second terminal wire also connected to the first terminal. An RF signal is placed on the first terminal and then its presence is detected on the second signal wire. This method and system can also be placed on each phase of a three phase system.

Absence of voltage detection device

In one embodiment, a power supply circuit has a power source, an inductor in series with a switching transistor connected to the power source, a pair of isolation capacitors connected across the switching transistor, a load connected to the isolation capacitors such that they isolate the load from low frequency energy from the power source, and a resonance circuit configured to amplify resonant ringing connected at least one of in parallel to the inductor or in parallel to the switching transistor.

DC voltage detector isolation circuit

Disclosed herein are various implementations of communications connectors. In some implementations, a communications plug may include a housing and a body positioned in the housing. A flexible printed circuit board (PCB) may be wrapped at least partially around the body, a and a plurality of metal contact pads may be positioned on the flexible PCB to mate with plug interface contacts (PICs) of a communications jack when the communications plug is inserted into the communications jack.
