Veelgestelde vragen over producten:

Q: What maintenance practices are recommended for 11kv three phase metering potentiële transformatoren?

A: Regelmatige onderhoudspraktijken omvatten:

1.Visuele inspecties: Controleer op fysieke schade, corrosie of tekenen van oververhitting.

2.Cleaning: Remove dust and debris to prevent insulation breakdown.

3. Testen: voer periodiek isolatieweerstands- en verhoudingstests uit.

4.Calibration: Ensure accuracy by calibrating against known standards.

5. Goed onderhoud zorgt voor een lange levensduur en betrouwbare prestaties van PT's.

Q: What is the primary function of an 11kV three phase metering potential transformer?

A: An 11kV three phase metering potential transformer is designed to step down the primary voltage to a lower, standardized secondary voltage, typically 110V, for accurate measurement and monitoring of electrical parameters in primary voltage systems. The 11kV three phase metering potential transformer pt allows metering instruments and protection relays to operate safely and effectively.

Vraag: Wat zijn de typische nauwkeurigheidsklassen die beschikbaar zijn voor een 11kV driefasige meetpotentiaaltransformator pt?

A: Accuracy classes commonly include 0.2, 0.5, and 1.0 for metering, and 5P10 or 10P10 for protection, according to IEC 61869. The required accuracy depends on whether the PT is being used for revenue metering or for relay protection functions.
