DTT – Direct Transfer Trip
Automated Direct Transfer Trip solution is implemented to control the Utility Connection to a Distributed Energy Site (solar farm, wind mill etc.). Connecting/Disconnecting DG site is very critical to the stability of the distribution grid. Really impacts the power reliability to the end customers and utilities are always challenged by the irregular generating/consuming patterns of a DG. DTT automated solution aims at
  • Maintaining DG connection during temporary loss of communication
  • Providing Anomaly Detection Protection
  • Providing true redundant communication capability
  • Providing Event and Fault Reports to operators
ASTS – Automatic Source Transfer System

Automatic Source Transfer solution protects the load from a loss of power supply by automatically disconnecting the load from the faulted primary power source and reconnecting to the backup feed. Source transfer is accomplished by (IEDs) automation controllers. Each controller governs the operation of switchgear (switch/recloser/circuit breaker) situated on both sides of the critical load using IEC61850 communication protocol over a communication network. When a loss-of-source is detected, the recloser on the faulted side opens while the other closes to maintain power to the load. The system operates autonomously in a peer-to-peer fashion with no need for master control. Incoming data to the controllers is checked periodically and any unexpected delays will cause a communication fault to be issued. For the loss of source detection, either internal or external PTs to the switchgear are installed on the source side of the feeder. Once an undervoltage condition is detected, the controllers immediately initiate the source power transfer.
