A Control & Relay Panel (CRP) solution is designed to control several feeders, through medium voltage indoor and outdoor switchgear in a primary distribution substation.
It is typically deployed when associated switchgear does not have space to accommodate the protection, control, and monitoring needs of a substation.
The CRP solution can also be extended to incorporate substation HMI, time synchronization, metering and networking functionality in the substation and thereby avoid requirement of a separate control room.
By deploying CRP solutions also enhances the safety to the substation engineer, as exposure to a live switchgear is mitigated.
And therefore, it is designed and customized to fully suit requirements of a particular customer site.
Scope
- Used for protection, control. measurement & monitoring of electrical equipment such as transformers, generators, busbars, cable or line feeders, bus couplers, capacitor banks, voltage protection etc.
