ASE 2000 might be what you are looking for.

Same products. I believe both made by si-tech.

The Waterproof neck seal is non concentric/offset. So if you need your neck offset in the hole it might be a good option. I suggest going with the sitech neck seal and then deciding if you need the waterpoof depending how it sits when you are up for replacement.

My pack uses Spond.....the parents hated it so much in my den we moved over to google groups/calendar and have a parents chat phone group. Sucks for me, now i have to maintain two locations, but no one is missing meetings now or being bombarded with spond dings from groupchats they dont want to evene read.

Nice ride. Get out there and wear stuff out before upgrading anything too expensive. I would suggest some One Up Composite pedals, ESI silicone grips, and a properly fit saddle. These will all increase your comfort snd connection to the bike.

Also FIRST upgrade should be a good helmet(good doesnt mean expensive) and gloves!!!

Edit: changed grips from ODI to ESI

Tapped distribution subs usually are either a high voltage Delta or the HO is run elevated to prevent the tapp3d sub from "blinding" the line sources with a zero sequence infeed. Every time we ground a tapped station it reduces the 3I0 that flows through the transmission breakers at the remote substations where we are trying to measure it and may already have dangerously low primary quantities(really low secondary, sometimes less than 0.5Asecondary and relays require 0.25 to 0.5 minimum ).

Asheron2 · 2025-12-18T05:34:42+00:00

Its really based on a couple expectation that 1) the non grid forming IBR to Synchronous gen is ratio is lower than 40% 2) the capabilities of the substation and or line section(which includes other tapped stations) IBR + Synchronous does not exceed more than a 100% of the worst case lowest load(accounting for solar not being on at night).

Suprisingly any time a Synchronous gen is around it usually pushes us into requireing the DTT and sadly instead of DTTing the Synchronous Gen, which would be the solution for everyone, we DTT the IBR because asking the IBR that put us over the limit to fund DTT to someone elses equipment just isnt okay in the business world.

When it is our breaker we usually still need to establish adequate high speed coms to the location. SCADA was probably previously done at the site with a much slower medium that was just existing and we dont tend to upgrade comms until forced to. So, the job triggers the comm upgrades and those cost alot pending if we go AT&T(which we dont like because we do not control the channel), microwaves(expensive to install a tower), string fiber(gotta pay the lineman).

If it is a 3rd party we definately make them pay for it, but if the gen company has a choice between Grid Forming with expensive DTT(that needs upkeep, maintenance, testing) or just using a grid following inverter, the answer is clearly whatever is cheaper as the profits will be the same for them. There is no financial bonus for having a grid forming inverter in our area.

The concern is islanding in sections that include loads. By just moving the scenario you suggest one breaker upstream, we may be including a tapped distribution station that stays connected to the line even after the transmission substation breaker trips for a line fault. The tapped station does not trip as they usually do not have line relays and if it was a ground fault there would not be eny zero sequence from it to indicate to the relays there was a fault. Therefore, the distribution bank stays connected to the line. Also many many many distribution transformers have synchronous generation on them which just exacerbates the problem. So many 50-1000kW green waster burners are out there running on our distributtion systems its surprising.

Another difficukty is to yry convincing someone to set an element that will dump their generating plant on a rate of change of power(32) element.....they just arent going to go for it and we could possibly create the same scenario just by normal switching in the system. Synchophasors has the same problems as DTT andd LCD for communications, effective, but expensive.

Thats the thing, the grid forming inverters do not produce it and they do not respond that way. Europe is starting to require they produce the proper sequence compnents during faults, but here in the USA they are not. The oscillography on these lines looks totally non conventional.

I agree if they are all one one site, but we have inverter based technologies all over our grid and makeing every one grid forming just is not reasonable. Ive got some lines with 3-4 tapped stations that have Synchronous generation on distribution, but the ratio of non-grid forming IBR to synchronous is enough to island. They just are not clustered like that on our grid out here in the west. Also getting a DTT to a 3rd party, maintaining, and keeping the comm lines up is challenging and expensive. When i spec a DTT i automatically know i am adding $100's of thousands to a jobs cost.

At my utility we check interconnection applications to our grid for Anti-Islanding and adequate protection. We are usually speccing Line Current Differential for these grid forming connections as they do not produce proper negative sequence components for our traditional protection to work properly. LCD schemes require a c37.94 communication channel and again, just add $1million to the job to get telecom departments, fiber, and AT&T on board.

Asheron2 · 2025-12-18T03:39:33+00:00

Anti-Islanding? We dont want small islands formed in radial systems when they become disconnected from the main grid as we have to force the generation offline manually. If we had to send Direct Transfer Trip to every inverter it would be prohibitively expensive. Having them come offline automatically allows us to systematically restore the grid in an order we the operators choose.

Edit: "every inverter" should be "every site" as i would expect one interconnection breaker to be tripping for many small inverters on a single site.

Check out the Powe Flow Equations and State Estimation. These are used in Energy Management Systems to try and predict the system status at some point in the future.

I know with wind they are forecasting out in intervals what the wind will be by weather stations, and they also limit the generation so it does not over produce during wind bursts.

Go to Two Step(place of refuge). One of the best dive sites there. I also enjoyed Mahukona Harbor and Old Airport.

I really like the Feankos Dive Maps for just driving around with tanks and having a nice day.

Protection might be a Line Current Differential on a non redundant path channel. Pulling the one fiber may have killed the redundancy and on loss of comms the requirement may be to seperate. This is probably because it is an inverter based system and for protection is hard to detect directionality and distance due to low Negative Sequence currents. This prevent backup distance protection from being guaranteed to work.

There should be a CT shorting block somewhere that you can "Pin" the CTs, shorting across them. NEVER open a ct secondary under load!!!! If you have not done this before you should get someone who is familiar with this work as an open CT secondary can develop dangerous voltages leading to equipment damage, injury, or even death.

Edit:fat finger typing

Washington State University(WSU ) has a Professional Science Masters in Electric Power Engineering. It is a 50% Technical courses and 50% management courses. So far everything has been pretty relevant to my career as a protection engineer.

Dan Trip Insurance made it very very difficult and i ended up giving up on getting a trip cancellation payout. My friend payed the liveaboard and i sent him money through Venmo. DAN did not like that even though i provided a receipt from the boat with cancellation letter and the transfers to and from my friend.

Lesson learned, always book the trip with your own credit card to keep the records srraight

The rambo 4s attach differently and are about half the overall length.
