  • Neta 2 exam prep

    Hey gents and ladies, I need help with my NETA 2 exam prep. I've taken it twice now and I made a 391 both times. I'm struggling trying to figure out what i should be focusing on. Yes, these tests are hard, but I feel like I am doing good then I just hit a wall towards the end of the exam. Any advice/tips is greatly appreciated.

  • How is X0 connected inside of a wye transformer configuration?

    Your response is in reference to symmetrical components. But the fault in your logic would be explaining it for Open Delta configuration or High-Leg Delta. These can still be visually and mathematically calculated using symmetrical components.

  • PI test show (OL) the tester reached the limits of reading 40G

    PI test is technically only viable if the 1 minute reading is below 5 gigohms and if required another form of insulation resistance is required: IEEE 43 12.2.2 Applicability of polarization index when IR1 is greater than 5000 MΩ When the insulation resistance reading obtained after the voltage has been applied for 1 min (IR1) is higher than 5000 MΩ, base...

  • FT Switches - Voltage on blade or not?

    Since Westinghouse made it's very first draw out relays (1940's), the standard has been that the blades go to the system and the jaws go to the relays. Failing to wire this way renders the factory designed test paddle useless and can create even greater safety hazards. The test switches are normally inaccessible due to the cover or relay case. If someone ...

  • PI test show (OL) the tester reached the limits of reading 40G

    Sounds like a pass. Document it. I've had to include pictures when my MEGGER maxes out because just putting a 3TOhm~ as a result for minutes 5 and up with a flat line graph doesn't really relate to non testers.

  • Difference between NETA ATS 2017 and 2021 for testing newly installed transformers

    Its always best to go with the most recent version of any standard however there are likely few if any major differences between ATS 2017 and the forthcoming 2025. It’s unlikely that every test is required in the standard. How much testing is done depends on the transformer’s intended duties, budget, and reliability requirements.

  • Difference between NETA ATS 2017 and 2021 for testing newly installed transformers

    "Are there any differences in the testing methods for newly installed transformers? The transformer in question is a 22.9kV transformer. (The voltage of transformers differs between the US and South Korea.) Our company currently possesses the ATS 2017, but we are considering purchasing the 2021 edition if there are significant differences. If there are no di...

  • Measuring Capacitance Across A-B Terminals

    Your answer is correct (1152). The reason why is: 1- Qtotal = 100KVAR. and each Capacitor in the bank will give you 33.33KVAR. 2- Now Q = V^2/Xc --> Xc = V^2/Q --> Xc= 277^2 / 33.33KVAR --> Xc = 2.3 Ohms Per Capacitor. 3- Xc = 1/2 * Pi * f * C --> C ~ 1152 MicroFarad.

  • PI test show (OL) the tester reached the limits of reading 40G

    Reducing the voltage to 500V is not a good method. Prepare the device manual indicating that the measurement device displays 'OL' when it exceeds '40G', and take a photo showing 'OL'. In the report, note it as 40G< and then calculate the PI as 40G.
