Integrated, electric-racking system

Type SIERS

Siemens Integrated Electric-Racking System (SIERS) provides additional personnel protection against arc-flash exposure for operators by providing a means of remotely racking the drawout circuit breaker for Siemens types GM-SG non-arcresistant 5 kV-15 kV, GM-SG-AR arc-resistant 5 kV-15 kV and

GM38 non-arc-resistant 38 kV switchgear.

SIERS delivers a safe, easy-to-use, cost-effective, reliable and flexible way to remotely rack a drawout circuit breaker while standing outside of the arc-flash zone. This reduces the need for personal protective equipment (PPE) per the NFPA-70E® standard.

Safety

Maintain all of the safety interlocks as required by IEEE

Std. C37.20.2

If interference is experienced while racking, the circuit breaker will attempt to return to the DISCONNECTED position

The control pendant (hand-held controller) provides clear light-emitting diode indication of the location of the circuit breaker in the CONNECTED, DISCONNECTED, and

TEST positions

When plugged into a specific circuit breaker compartment, the control pendant will override any electronic control system (HMI, SCADA or similar).

Easy to use and operate

User-friendly control pendant with easy to read display and controls

Provisions for energizing the SIERS with an external

120 Vac power supply with an extension cord (optional)

High-torque, fixed-mounted motor in the circuit breaker compartment provides smooth and efficient motion of the circuit breaker from CONNECTED position to the TEST position, or to the DISCONNECT position.

Reliable

Logic to sense interference issue during racking

Operation is smooth and consistent

Control pendant is industrial class

Factory installed and tested as a complete racking system.

Flexible

Powered from a control power transformer located in the switchgear at 120 Vac, or by an external supply (either

120 Vac or 125 Vdc)

Controls can be integrated into the switchgear secondary control circuits interface with the protection relay to provide interface with SCADA systems, local HMI or discrete wiring

Type SIERS device is available in three configurations: basic version, local HMI version (Smart-Gear® power distribution solution), and custom version, e.g.,SCADA or other systems

Available as a field retrofit for existing Siemens types

GM-SG, GM-SG-AR and GM38 switchgear.

Description

Each circuit breaker cell is equipped with an integrated, electric-racking system, which includes a fixed-mounted, hightorque motor and logic control module, control-pendant connector powered by control power in the switchgear or an external supply (either 120 Vac or 125 Vdc) when necessary. Typically, one control pendant is supplied per lineup.

Type SIERS integrated, electric-racking system - one per circuit breaker cell

Control pendant – one per lineup.

Basic type plus local HMI panel PC interface with GM-SG, GM-SG-AR or GM38 lineup(s) in the electrical room:
