FAQ

Yes. Register for a scheduled paired course and/or for consecutive courses within 7 days of each other and save 10 percent.

High-voltage arcs can also produce considerable pressure waves by rapidly heating the air and creating a blast. This pressure burst can hit a worker with great force and send molten metal droplets from melted copper and aluminum electrical components great distances at extremely high velocities.

Yes, SEL encourages candidates to apply for each position for which you believe you are qualified. You will be considered for each position individually.

No. CBTs are highly interactive and rich in multimedia content. There is no way to capture the course within a PDF without removing that content first.

Yes. You will have one year from the date you purchased your CBT to access the material as often as you like. Once successfully completed, the course will open in Review Mode, which means that you can do everything except submit the final knowledge check score.

No, please be aware that each candidate must have a unique identifier (email address). Therefore, email addresses cannot be shared among applicants. If you do not have an email address, you can create one using one of the many free email accounts available online.

Arc-flash energy is proportional to V•I•t. Relays don't have any control over the voltage and current. The voltage across an arc is determined by the conductor gap; the arcing current is limited by the available fault current. What the relay can impact is time. By limiting the duration of the arc-flash event, the relay can dramatically reduce the amount of incident energy produced by an arc-flash event.  

The recent changes (i.e., servers hosted by CacheFly and how Compass detects the route to the Internet) may result in Compass reporting that it is not able to find the update file at the source location. Outlined below are known remedies for the aforementioned message.

If you know the proxy information, enter that data into the appropriate field in Compass. Enter the proxy information by selecting from the menu bar: Tools -> Options -> SEL User Account. At the bottom of the SEL User Account Logon Information form, you will see the space to enable and enter the settings for a proxy server.

Alternatively, your company’s IT/IS group can add exceptions to the routing tables, which will allow Compass access to needed sites. All the necessary links are listed below.

Besides being the list of sites to which Compass needs access, the list below is also the order used by Compass to download needed items. For Compass versions prior to v3.0.4.8, the following links apply:

1. https://customer.selinc.com/compass/proxy.php.
2. https://www.selinc.com/myaccount/compassProxy.aspx.

For Compass versions starting at v.3.0.4.8, the following links apply:

1. https://selinc.com/api/cms/login
2. https://selinc.com/api/cms/logintwofactor
3. After verifying Internet access and user credentials SEL Compass then redirects to a different location based on the package chosen to download.
   1. Software packages, like acSELerator QuickSet, get redirected to https://selinc.cachefly.net.
   2. Other packages would go to *.selinc.com.
4. Certificate resolution is done via crl.comodoca.com.

Items we have seen that will interfere with the process:

• The number of redirects allowed is too small.
• Compressed (*.ZIP) files from the above websites need to be allowed.
• While CacheFly does not use streaming, blocking of streaming may blacklist CacheFly sites. We believe this is because CacheFly can stream data, and the “blanket” block is stopping Compass from getting to CacheFly.

The standalone installation for the software is available for download from: https://www.selinc.com/SEL-5030.

No. Right now, all we need is your resumé. SEL does not require a formal application with work history and background-check authorization until later in the hiring process.

Yes, SEL offers complete metering solutions and engineering services. Visit the Metering Solutions page for more information.

The SEL-735 offers high-accuracy measurements with a ±0.06 percent Wh guarantee at unity power factor and a ±0.02 percent typical rating. It outperforms the requirements of ANSI C12.20 and IEC 62053-22 accuracy class 0.2.

The basic synchrophasor system building blocks are GPS satellite-synchronized clocks, phasor measurement units (PMUs), a phasor data concentrator (PDC), and visualization software. Multiple PMUs provide synchronized phasor measurements from across an interconnection to a PDC which collects and aligns the data for analysis. Synchrophasor systems have a wide variety of applications and are currently being used for real-time situational awareness, disturbance recording and analysis, wide-area monitoring and control, high-precision state estimation, system model verification, and island detection, just to name a few. The evolution of synchrophasor technology will enable innovations in smart grid technology.

In the terminal window, go to access Level 2 . Type in "FOR 5" to convert the meter to a Form 5 meter, or "FOR 9" to convert it to a Form 9 meter. Follow the prompt, and then confirm the change to change settings.

Consult our campus map or contact your recruiter, who will be happy to help provide directions.

SEL accepts payment by credit card, check, or purchase order. A copy of the PO must be provided for our records, as well as billing purposes, before the registration can be processed.

SEL can help you secure your communications paths through system design and by using secure communications devices. By using a PDC in your substation, all PMU communications go through the PDC, providing a layer between the PMU and the outgoing communications. Using the UDP_S protocol out of the PDC further secures the communications out of the substation because all inbound communications are ignored by UDP_S. Finally, SEL offers serial encryption devices, secure Ethernet gateways, etc., to secure communications into and out of your substation.

All course material can be accessed through your mySELU Training page, https://learn.selinc.com/accounts/profile/.

We ask all candidates to submit their resumés through our website:

1. Select Apply Now from the menu.
2. Click the Search button in the middle of the screen on the right (or if you would like to specify a job category or location, do so, then click Search).
3. Select the position title that interests you. Then select Submit Your Application.
4. Log into your existing account, or create a username (your email address) and password. After logging in, you can upload your resumé and cover letter to complete the application process.

Registrations from non-company-specific domains (Gmail, Hotmail, etc.) are granted limited access and are subject to review based on your need for resources. Most account reviews are processed within two business days. If you need an expedited review, please email web_account_review@selinc.com.

Since arc-flash energy is proportional to V•I•t, the protective relay acts to reduce the duration of the arc-flash event, or “t.” (Note: In an arc-flash event, this equals the time elapsed before the relay trips plus the breaker clearing time.)
