Current transformers (CTs) and voltage transformers (VTs) feed your metering and protection systems — errors here undermine both. Controware tests instrument transformers for commissioning and troubleshooting across the UAE, KSA and Egypt.

Tests we perform

CT ratio, polarity and winding resistance.
Saturation / knee-point (excitation) curve.
Burden and secondary injection verification.
VT/PT ratio, polarity and insulation.

Results feed directly into protection relay testing and coordination studies. Back to the power testing division.
