Phase current unbalance (ANSI 60P, IEC PVCB/PTOC) _ Element settings & highlights _ GU8081

Posted on by Firoozeh

Overview

The “Phase current unbalance” element responds to a differential current signal measured via window-type CTs as a vectorial current difference between two parallel banks. With the two capacitors in the same phase identical, the said differential current is zero. Small differences between the capacitors of a given phase result in a small circulating current.

For more detailed information on “Phase current unbalance” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.

Overview

The “Neutral current unbalance” element responds to a differential current signal measured as a vectorial current difference between neutral currents of parallel banks. In case of ungrounded banks, regular, preferably low-ratio CT can be used. In case of grounded banks, a window or core-balance CT shall be used for increased accuracy/sensitivity.

Overview

The “Capacitor control” element gathers on/off commands from various sources and executes them, while maintaining remote/local and auto/manual control rights. Local control refers to control from the front panel of the relay. Remote control refers to control via communications from outside of the relay, an on-site interface, and/or from an off-site control center.

For more detailed information on “Capacitor control” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.

Overview

The “Trip output” element is primarily used to collect trip requests from protection elements and other inputs to generate output operands to initiate trip operations. Three pole trips only initiate reclosure if programmed to do so, whereas single pole trips always automatically initiate reclosure.

Setting groups _ Element settings & highlights _ GU8243

Posted on by Firoozeh

Overview

The “Setting groups” menu controls the activation and deactivation of up to six groups of settings in the GROUPED ELEMENTS settings menu. On a setting group change, protection elements are blocked temporarily to allow the relay to re-initialize with the new settings. The duration of the block depends on relay configuration and can last up to four cycles.

For more detailed information on “Setting groups”, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.

Trip bus _ Element settings & highlights _ GU8242

Posted on by Firoozeh

Overview

The “Trip bus” element allows aggregating outputs of protection and control elements without using FlexLogic and assigning them a simple and effective manner. Each trip bus can be assigned for either trip or alarm actions. Simple trip conditioning such as latch, delay, and seal-in delay are available.

For more detailed information on “Trip bus” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
