2018 Kia Niro PHEV Review – A Spreadsheet Nerd’s Dream | Lrd12 Overload Relay

i built the rig that day. I put an ammeter with max hold on a circuit, plugged the circuit into a known 20 amp connection, and put a load on the circuit that simulated the instrument. Turn it on, 22 amps max hold, 13 amps nominal.

– Use isolated differential probes to measure high voltage. – Use current clamps or current transformers to measure current. – Put bleeding resistors in any big capacitor in your circuit. – Don’t change the position of the probes in the power circuit without power everything down. – Don’t work with high voltages alone. – If there’s more people involved in your experiment, block any circuit breaker, button or at least put some signs to prevent people from turning them on while you are messing with the circuit. Paranoids may even ground things while they are playing with the installation to direct the current to the ground in case someone makes a mistake.

I came here to post those two points! The corollaries to 1) are that should something go wrong, you have a chance if there is someone else there who knows CPR. I like mandatory CPR training for lab workers because of this. AEDs are good too. Rules against playing with things that can shock you while working alone are also good, but much harder to follow–I’ve spent decades working alone in research labs. CPR fails way more often than not, but electrical shocks are an important exception to that rule. And you almost got the extra credit for correctly spelling arrhythmia.

Translucent (pellicle) mirror. Undoubtedly the biggest story of the Sony SLT-series cameras is their use of a translucent mirror. Also known as pellicle mirror, this works by allowing most light to pass through to the imaging surface beneath, while a small portion is reflected for other purposes. Sony is not the first camera manufacturer to use a translucent mirror in an SLR-style camera, with the manual focus Canon Pellix film camera from 1965 taking that credit. The Pellix was followed by a handful of other pellicle mirror-based SLRs from Canon, Nikon, and Mamiya, largely designed for professional photographers, and manufactured in very limited production runs. It wasn’t until 1989′s Canon EOS RT that the first autofocus pellicle camera was released, followed by the EOS-1N RS in 1995. Fifteen years later, Sony has become the first company to resurrect the pellicle mirror for use in an interchangeable lens digital camera.

The best tip for buying a portable home generator: Don’t wait until the lights go out. Whether you live in a place at the mercy of snowstorms, hurricanes, heat waves or an outdated electric grid, a power outage can range from an annoyance to life-threatening.

From the Auris to this, haven’t Toyota learnt anything. It’s just a slightly bigger and slightlly less DULL than the car it replaces.

I would say however that relying on the relay coil is not reliable at all, and there are a variety of somewhat more accurate methods that I would prefer to rely upon.

All this stuff makes me think it might be time to get a Faraday cage installed around my heart. Or maybe a big shunt from shoulder to shoulder.

The real problem with mains voltages is that somewhere, some day, some bonehead will manage to fry himself – and the media will blame the maker movement for it. I’ve already seen far too many absolute beginners planning to wire up their home appliances to an Arduino as their first project…

Terminals 4 and 6 are used for capacitors and/or condenser fan connections and have no electrical significance to the starting relay itself, as shown in Figure 1. In fact, terminals 4 and 6 are sometimes referred to as “dummy” terminals and are simply used for wire connections.Figure 2 shows how a potential relay is wired to a capacitor-start/capacitor-run compressor motor. Notice that the relay coil is wired in parallel with the start winding and the start capacitor.

That said, 12A @ 240V is only a little less than the most our Volt will use even on a proper charger, so it’s still a good thing.

We first saw this feature in Sony’s DSC-TX1 and DSC-WX1 in mid-2009. Since then, it’s been mimicked by other manufacturers, but none seem to do it as well as Sony. In Handheld Twilight mode, the camera captures up to 6 shots in rapid succession, micro-aligns them with each other, and then adds them all together. The net result is that you can hand-hold ridiculously long exposures and still get sharp results, with very low image noise to boot. Combine this with Sony’s SteadyShot image stabilization and sharp handheld photos at half-second exposure times are feasible.
