1.4 An Bambanta Abubuwan Fanni?

Toki bayan hakan, VTs biyu suna iya kasance da hakan, amma abubuwan fanni suna iya kasance da ƙarin wahalar.

Misali:

• Akwai model na ABB wanda suka da built-in protection features;

• Model na Siemens yana iya da communication protocol ko user interface mai tsari.

Idan za a kawo karfi, bar da adadin da ABB VT ya fi kawo karfi da abin da ake amfani da shi — musamman babban abubuwa kamar protection logic da metering accuracy.

2.Ziyartar - Abubuwan Muhimmanci Suna Yawan Ziyarta
2.1 Idan Za Ka Yi Ziyarta, Bar Da Adadin Da Ake Amfani Da Shu!

Ba a karkasha wannan halin — akwai mutane wanda suka tabbatar da su suna so kuɗi bayan an kawo karfi.

Wannan ne ina yi daga cikin zaman:

• Bar da hoto da ake amfani da shi idan za a yi ziyarta;

• Label terminal blocks and connections carefully;

• Yi koyarwa don abincin da zaka iya amfani da shi a cikin zamani;

• Plan out each step of the installation process.

Idan ka koyarwa, za a iya yi ziyarta da ƙarin kowa.

2.2 Grounding Ba Wani Abu Da A Kan Karkasha!

Grounding yana da muhimmanci a kan ƙarfin — ba a kasa ba!

• Bar da adadin da grounding na ABB VT ya fi kawo karfi;

• Amfani da wires mai tsari;

• Test the grounding resistance to ensure it meets standards;

• Apply anti-corrosion treatment to prevent rust and poor contact over time.

Equipment na gida yana da zan iya neman harsuna, saboda haka, ƙarfin grounding yana da tasiri mai yawa a kan tsari da ƙarfin.

2.3 Ba A Karkasha Polarity Testing!

Akwai mutane wanda suka sonka polarity testing ba ya fi muhimmanci — yana da al'amun!

• Idan polarity yana ƙasance, yana iya haifar da alamun matsala a cikin differential protection circuits.

• Perform a polarity test after installation to confirm that the primary and secondary terminals are correctly aligned.

Idan za a iya ziyarta, za a iya zaba wani abu mai yawa, amma yana da muhimmanci a kan ƙarfin da ƙarfi.

2.4 Ba A Power It Up Immediately After Installation — Test First!

Ba a kasa a yi power — wanda yana da al'amun!

At minimum, run these tests:

• Insulation resistance test: Check for insulation integrity;

• Power frequency withstand voltage test: Verify it can handle rated voltage;

• Ratio test: Confirm actual ratio matches nameplate;

• Error test (for metering-grade VTs): Ensure measurement accuracy.

Proceed only once all tests pass.

2.5 Finally, Do a Full System Integration Test!

Remember, the VT doesn’t work alone — it’s part of a larger system.

• Connect it to the protection relay, monitoring system, and check if data acquisition is normal;

• Run it under load for a while and observe its performance;

• If any issues pop up, fix them right away — don’t wait until full operation starts.

3.Wrap-Up Thoughts

As someone who’s spent 10 years in the outdoor VT game, here’s my takeaway:

“Replacing a device isn’t just swapping out the shell — it’s about making sure the new one truly integrates into the system.”

If you're still struggling with selection or worried about potential installation issues, remember these key points:

• Consistent technical parameters;

• Compatible installation dimensions;

• Environmental adaptability;

• Functional compatibility;

• Thorough pre-installation preparation;

• Correct grounding practices;

• Strict electrical testing procedures.

These will not only save you time, but also significantly reduce the risk of equipment failure.

If you run into any problems during the replacement — whether it’s installation difficulties, failed tests, or system incompatibility — feel free to reach out anytime. I’d love to help you troubleshoot and offer real-world advice.

Here’s hoping every outdoor voltage transformer runs safely, stably, and efficiently — quietly guarding the power grid like a true unsung hero.

4.Frequently Asked Questions (FAQ)

Q1: Can the original protection settings still be used after switching to ABB voltage transformers?

A1:Not necessarily. The output characteristics of different brands may have slight differences, especially regarding secondary-side voltage waveforms, internal resistance, response times, etc.

After replacement, it’s recommended to recheck the protection settings and, if necessary, perform a load test to ensure that the protection logic remains effective.

Q2: Will the wiring method change? Can the terminal block from Siemens be directly connected to ABB’s?

A2:Most of the time, the wiring methods are compatible, but it depends on the model.Some ABB models might have different terminal arrangements or labeling conventions. It’s advisable to carefully compare the wiring diagrams of both old and new equipment before installation to avoid miswiring which could lead to failures.

Q3: Could the replacement affect data acquisition in the backend monitoring system?

A3:It’s possible! Especially if your original system was specifically configured for Siemens equipment.For instance, communication protocols (like IEC61850), data formats, and range mapping might differ, requiring adjustments or reconfiguration in the backend SCADA system.
