Product Q&A
Q:What is the difference between this tap-changer and an OLTC?
A:
This is a no-load tap-changer that must operate only when the transformer is de-energized, unlike OLTCs which switch under full load.
Q:What is the maximum voltage for this model?
A:
The WST II is designed for medium voltage networks up to 10 kV.
Q:How many taps are available per phase?
A:
The Type II configuration features six taps per phase connected to the mid-point of the high-voltage winding.
Q:What safety protocols must be followed?
A:
Strict adherence is required to prohibit operation under load to prevent arcing and equipment damage.
Q:What testing is required after installation?
A:
Post-adjustment DC resistance testing is mandatory to confirm contact integrity.
