Siemens RC Voltage Dividers Air-insulated switchgear

Siemens RC Voltage Dividers : Resistive-Capacitive Voltage Dividers are designed for measurement and protection in HVDC transmission systems, and AC air insulated (AIS) or gas insulated (GIS) switchgear.

For DC: The measuring system consists of an RC voltage divider which provides inputs to a specially designed electronic power amplifier. The resulting system can accurately transform voltages within a defined burden range with linear frequency response. As such, the system is ideal for measurement for dynamic and transient phenomena and harmonics associated with HVDC systems.

In AC transmission systems: used for the measurement of Power Quality as harmonics, overvoltage’s, flicker, due an accurate representation of the voltage over a wide frequency band, and are not sensitive to the trapped charges phenomena. Furthermore the so-called RCVTs can be used for measurement and protection purposes in modern low burden applications, such as Digital Substations.

Siemens RC Voltage Dividers Main Features:

• Hermetically sealed construction
• Stainless steel expansion chamber
• High seismic withstand design available
• Provides an accurate and reliable image of the voltage on the HV line to measure and determine the origin of disturbances
• Accurate over a large frequency range
• Excellent transient characteristics
• As RCVTs do not have any saturable cores, they cannot get into ferroresonance
• Not affected by the discharge of the line: no risk for the unit
