Basler Electric 81001-451-62-R 1500A SGCT Matched Set – Solid-State Ground Current Transformer Series
When a ground fault current transformer fails or goes out of calibration in a high-voltage protection relay system, the consequences are immediate and severe: nuisance trips, undetected ground faults, generator damage, and potential catastrophic equipment failure. In mission-critical power generation and industrial distribution environments, every millisecond of undetected fault current matters. The Basler Electric 81001-451-62-R Matched Set of (2) 1500A Solid-State Ground Current Transformers (SGCT) is the precision-engineered solution that keeps your protection relay system operating with the accuracy and reliability your facility demands.
The 81001-451-62-R occupies a specialized position within Basler Electric’s SGCT product family. Designed specifically for use with Basler Electric’s BE1-GPS100 and compatible generator protection relay platforms, this matched pair configuration ensures balanced differential current sensing at 1500A rated primary current. As one of the most trusted names in power system protection since 1942, Basler Electric’s SGCT series is deployed across utilities, industrial plants, and power generation facilities worldwide — making genuine replacement parts like the 81001-451-62-R essential for maintaining OEM-level protection performance.

Frequently Asked Questions
Q: What does “Matched Set” mean for the 81001-451-62-R?
A: It means the two SGCT units in the set have been factory-calibrated and verified to have matched output characteristics. This is critical for differential protection schemes where both CTs must produce identical outputs for the same primary current to prevent false trips or missed faults.
Q: Is the 81001-451-62-R compatible with non-Basler Electric relays?
A: The SGCT is optimized for Basler Electric relay platforms. While the electrical output may be adaptable, we recommend consulting your relay manufacturer’s documentation or contacting our technical team before using it with third-party protection relays.
Q: Can I order a single SGCT unit instead of the matched set?
A: The 81001-451-62-R is sold as a matched pair only. If you require a single unit or a different current rating, please contact us — we can source alternative SGCT variants from the Basler Electric catalog.
Q: What is the lead time for international orders?
A: Standard lead time is 3–7 business days for in-stock inventory. For urgent requirements, express procurement is available — contact us with your timeline and we will confirm availability.
Q: Do you provide a certificate of conformance?
A: Yes. A certificate of conformance and full packing documentation are included with every shipment of the 81001-451-62-R.
