Transformer Protection  Demo Panel: (% Differential Protection):
Make: XEEPL, Model SGP-TX
It is also Called as Merz-Price Protection of Transformer .
  • Numerical Differential Protection Relay: It is designed using high-speed micro DSP, which sample all three-phase current through CT connection. The high-speed micro-controller samples this current through a 12-bit A/D converter. The micro-controller performs powerful Digital Algorithms to find out Amplitude of current signal, then this value is use for protection and metering function. All measurement is tuned to fundamental frequency. Each input current is also displayed on 20 x 4 LCD display for metering. This relay is provided with Triple slope characteristics for Protection i.e.
  1. Zero Bias Slope : Pickup range is from 10% to 100% in steps of 5%.
  2. Differential Bias Slope: Bias range is from 10% to 50% in steps of 5%.
  3. 2nd Bias Slope: The bias current value at which relay shift to 2nd Bias from 100% to 400% in steps of 100%.
