Areva KVGC 202 - Voltage Regulating Control Relay. Short technical description

Description

KVGC 202 - реле регулирования напряжения.Краткое техническое описание.Areva. Electronic Edition, 2004. — 8 pages.The KVGC relay provides regulation of the supply voltage within finite limits by controlling transformer tap changing.The KVGC202 relay can be used to maintain a regulated voltage supply to electrical equipment designed to operate within finite limits of its designed rated voltage. Failure to maintain a regulated voltage supply within these defined limits may cause extensive damage. Regulation is achieved by the operation of voltage regulating transformers of various types, the most common being the on-load tap changing transformer which maintains a stable secondary voltage by selecting appropriate tappings on the primary winding.Table of Contents:Key Features.Control Functions.Transformer Tap Change Control.Inter Tap Time Delay.Line Drop Compensation.Parallel Transformer Applications.Load Shedding & Boosting.Supervision & Monitoring Functions.Runaway Protection.Under/Over Voltage Detection & Blocking.Overcurrent Detection.Tap Position Indication.Tap Changer Maintenance.Tap Changer Failure Mechanism.Configuration.Password Protection.Ancillary Functions.Measurements.Default Displays.Records.Test Features.Hardware.Front Panel User Interface.Serial Communication.Technical Data.Input Ratings.Output Rating.Burdens.Thermal Withstand.Measurement Accuracy.Current Transformer Requirements.Opto-isolated (Digital) Inputs.Relay Output Contacts.Contact Durability.Electrical Environment.Product Safety.Additional Information.Cases.Information Required with Order.
