    What is the best PLC you recommend

    ABB has an upgraded version of the Procontrol P13 (formerly ALSTOM BlueLine), it's been controlling turbines for decades. You can see some information here at HTS-LLC.com

    Women in Engineering.

    Scenario: You own a small business, it pays your mortgage, puts food on the table, puts your kids through school. You need to hire an engineer. After hiring, you will spend 100K on training, benefits and pay before your new hire is billable. 2 candidates are more or less equal during the...

    governor droop control

    If this is in the, US all turbines above 10MW are required to operate in droop, no matter the mode. That being said they cannot make you do what cannot be done. But..you could take the speed setpoint - actual speed deviation and (with a suitable gain) add that to the back pressure measurement...

    Droop vs isochronous explained

    This is from NERC Training Document "Understand and Calculate Frequency Response" I think it pretty much says it all for Units >10MW in North America (an exception is the Maritimes where droop is 4%. As an interesting point NERC has been pushing a deadband of 0.018Hz now which pretty much...

    Droop vs isochronous explained

    The standard (FERC) for large utility units in the US is 5%. The simple definition is that % deviation in frequency that will result in a 100% change in load. In some definitions the 100% increase in load is replaced by 100% opening/closing of the main control valve.

    Australian looking into the US job market

    To be an expert in one specific engineering course/subject VS know all of them a little?

    Don't let the naysayers get you down. Yes you can make 200K or pretty close to it with 10 years experience. Specialize in gas turbine field service or commissioning, get a job with one of the big 3 (or soon to be big 2) put your life on hold, work all the hours you can until you are tired of...

    4-20mA Signal noise

    Agree, with IRstuff. Throw out the established 'norms". Try grounding at both ends, each end separately and even if you can get access to the shield elsewhere. play around with it, to get the best result.

    test oversped

    With respect to CCfowler's comment (and the comment by rotw) I would disagree. A lot of insurance companies require testing of overspeed once a year as part of regular maintenance. Many OEM require it after major overhauls with turbine/compressor blade replacement. Normally the mechanical...

    steam turbine siemens

    If you turn off the Voltage regulator - no generator voltage - no overfrequency

    steam turbine siemens

    Ok, then turn off the AVR either from HMI or locally, before doing the overspeed test.

    Health Insurance

    Kenat, My point is that if companies did not include health insurance as part of a compensation package but instead gave the cash, when you had to write the check every month, you might pay more attention to whether or not you have the correct insurance and whether or not you have the best...

    "Engineering" in business name

    So how does it work? Let's say my company tests widgets. I can pay my buddy who is a PE $50/week to be on my staff and I can call my company XYZ engineering as long as I don't actually do any "engineering"?

    Health Insurance

    Personally I think it should be illegal for an employer to provide health insurance. Make everybody write a check each month and see what happens. It will be similar to the change in attitude that is experienced when an individual leaves an employer and starts a small business and has to write...

    Synchronizing Checks

    I Didn't take a picture but I will next time. Think of 3 sF6 breaker poles on insulators supported by horizontal steel members. The plates can be actually further away than the closest grounded part mounted next to the insulators that support the bus on both sides of the breaker. The plates...

    Synchronizing Checks

    We did both methods, the method I described and also the backfeed. The backfeed method is takes way longer and more labor. So I'm trying to figure out if I should use the induced voltage measuring method instead. The only downside that I can come up with is perhaps safety. This is the part...

    Synchronizing Checks

    We tried this idea to verify synchronizing a 15KV 120 MVA generator across an SF6 Breaker. Note: we also did all the usual checks, backfeed etc. We constructed six metal plates with insulated backs and taped them to the breaker pole frame right next to the insulators on each pole, for each...

    options for compensation for travel

    I'm a service engineer, US based, salary plus OT. I have never, ever, ever traveled for work (billable job) without getting paid my hourly rate. Sometimes, rarely, it is limited to 8 to 12 hours, but I have charged 24 hours when I've traveled 24 hours. Don't sell yourself short, it's not that...

    Vector Group

    I don't get it, if you swap the primary you change the phase rotation on the secondary, the vector group will be the same. If you swap the primary and the secondary, you have effectively done nothing and the vector group will also be the same.

    Which DMM can you recommend?

    As far as warnings for blowing fuses while on the wrong setting, it's hard to beat my Dranetz. It has a shutter to prevent you from inserting a probe in the current jack when you are in voltage setting, and when the probe is in the voltage jack you can't move to current and vice versa. you...
