The new MRCT software (PowerDB 10.5.4) and firmware (v1.253) includes the following key improvements:
• The nominal and operational burden at various current levels are now taken into consideration when measuring CT ratio and phase angle accuracy
• Test reports can now be configured to show tables and graphs of ratio and phase angle accuracy at various calculated burdens
• Improved amplifier circuitry protection
The new software and firmware will be installed on all production units effective immediately. They are backward compatible on all fielded systems. We recommend all customers download the latest version to take advantage of these enhancements.
