Application for testing Self-powered relays SEG (Woodward) WIP1 and WIC1
Application Note
%20WIP1%20and%20WIC1%20SVERKER900.png)
Self-Powered-Relay (SPR) takes its supply from the CT-s connected and also the energy for tripping the breaker. SPR either has special CT made for the relay or is made to be used directly with standard CT-s.
There are differences in how to set Sverker 900 when testing SPR that must be noticed.
1. The level of pre-fault current and time needed for pre-fault.
2. The pickup level for trip signal if not dry contact is used.
Here secondary testing of SEG relay (formerly Woodward) WIP1 and WIC1 will be described.

Using Fixed Thermal Imaging to Identify Dangerous Hot Spots in Coal or Biomass
APPLICATION NOTE
Continuous coal and biomass monitoring is an important step in understanding the conditions leading to a fire. Hot spots can flare up devastating spontaneous combustion, potentially causing thousands of dollars in material loss, dangerous work conditions, and difficult extinguishing options. Prevention is becoming readily available with cost-effective continuous thermal image monitoring as a method for early warning.
