Line differential protection (L4CPDIF) _ Setting & highlights _ AB2123


Overview

High speed “Line differential protection” for 4 CT sets, 2-3 line ends (L4CPDIF) is a unit type protection system with typical operate time less than one cycle. These types of systems are suitable for the protection of complex transmission network configurations because they exhibit good performance during evolving, inter-circuit, and cross-country faults.

For more detailed information on “Line differential protection”, refer to ABB, Relion 670 Series manuals.

Self adaptive differential protection for two-winding power transformers (PSTPDIF) _ Setting & highlights _ AB2121


Overview

The “Self adaptive differential protection for two-winding power transformers” function can be used as a differential protection for any two-winding three-phase power transformers. It is especially suitable for the differential protection of phase-shifting transformers (PST), which is also called phase-angle regulating transformers (PAR). This function is similar to the standard transformer differential protection function T2WPDIF (or 87T), but it can be applied to any type and construction of PST.

For more detailed information on “Self adaptive differential protection for two-winding power transformers” function, refer to ABB, Relion 670 Series manuals.

Low impedance restricted earth fault protection (REFPDIF) _ Setting & highlights _ AB2120


Overview

The “Low impedance restricted earth fault protection” function can be used on all directly or low-impedance earthed windings. The REFPDIF function provides high sensitivity and high speed tripping as it protects each winding separately and thus does not need inrush stabilization. It is a percentage biased function with an additional zero sequence current directional comparison criterion.

For more detailed information on “Low impedance restricted earth fault protection” function, refer to ABB, Relion 670 Series manuals.

Phase preference logic (PPL2PHIZ) _ Setting & highlights _ AB2032


Overview

The “Phase preference logic (PPL2PHIZ)” function is used with the high speed distance protection, quad and mho characteristic (ZMFPDIS). It is intended to be used in isolated or high impedance earthed networks where there is a requirement to operate on only one of the faulty lines during a cross-country fault. It can be used without preference to restrain operation for single earth faults with a delayed zero-sequence current release.

For more detailed information on “Phase preference logic (PPL2PHIZ)” function, refer to ABB, Relion 670 Series manuals.

Pole slip protection (PSPPPAM) _ Setting & highlights _ AB2029


Overview

Sudden events in an electric power system such as large changes in load, fault occurrence or fault clearance, can cause power oscillations referred to as power swings. In a non-recoverable situation, the power swings become so severe that the synchronism is lost, a condition referred to as pole slipping. The main purpose of the “Pole slip protection (PSPPPAM)” is to
detect, evaluate, and take the required action for pole slipping occurrences in the power system.

For more detailed information on “Pole slip protection (PSPPPAM)” function, refer to ABB, Relion 670 Series manuals.

High speed distance protection for series compensated lines (ZMFCPDIS) _ Setting & highlights _ AB2025


Overview

“High speed distance protection (ZMFCPDIS)” function is fundamentally the same function as ZMFPDIS but provides more flexibility in zone settings to suit more complex applications, such as series compensated lines. In operation for series compensated networks, the parameters of the directional function are altered to handle voltage reversal.

For more detailed information on “High speed distance protection for series compensated lines” function, refer to ABB, Relion 670 Series manuals.
