Digital Protective Relays: Problems and Solutions by Vladimir Gurevich
Other patents pending. The single-supply operation, on-chip filtering, and high input impedance eliminate the need for driver op amps and external bipolar supplies. The device contains analog input clamp protection, a dual, bit charge redistribution SAR analog-to-digital converter ADC , a flexible digital filter, a 2. The ADB is a bit, simultaneous sampling, analog-to-digital data acquisition system DAS with eight channels, each channel containing analog input clamp protection, a programable gain amplifier PGA , a low-pass filter, and a bit successive approximation register SAR , analog-to-digital converter ADC. The ADB also contains a flexible digital filter, low drift, 2. The single supply operation, on-chip filtering, and high input impedance eliminates the need for external driver op amps, which require bipolar supplies.

These devices play a vital role in power operations for fields ranging from manufacturing, transportation, and communication to banking and healthcare. Digital Protective Relays: Problems and Solutions offers a unique focus on the problems and disadvantages associated with their use, a crucial aspect that goes largely unexamined. While there is already a massive amount of literature documenting the benefits of using digital relays, devices as sophisticated as DPR obviously have faults and drawbacks that need to be understood. This book covers these, delving into the less familiar inner workings of DPR to fill a critical literary void and help decision makers and specialists in the field of protection relays find their way out of the informational vacuum.
