SCHLUMBERGER ST-Q220 RELAY DIGITAL With DISPLAY READ

Description:

The SCHLUMBERGER ST-Q220 Digital Relay with Display is used in three-phase power monitoring and protection systems to measure electrical parameters and provide relay-based control and indication functions. Commonly installed in industrial power distribution panels, substations, motor control centers, and utility metering systems requiring digital monitoring of 3-phase electrical networks. Maintenance teams, OEMs, and system integrators use this relay for replacement, retrofit, and power system upgrades to improve electrical monitoring, protection, and operational visibility.

Applications:

The SCHLUMBERGER ST-Q220 Digital Relay with Display is used to monitor and protect three-phase electrical systems in industrial and utility environments. It is commonly found in switchgear assemblies, motor control centers, substations, power generation facilities, and industrial control panels where real-time measurement, relay outputs, and digital display of electrical parameters are required. SCHLUMBERGER digital relays are designed to improve system reliability by detecting abnormal operating conditions and providing local indication and control functions.
