A voltage controlled overcurrent function can be enabled on the first two stages of the main phase overcurrent elements. Voltage controlled overcurrent provides back-up protection for remote phase faults whilst remaining insensitive to load. The directionality of the ground fault elements is provided by either residual voltage or negative sequence voltage polarising.

> Negative Sequence Overcurrent Four independent stages are available and each stage may be selected as non-directional or directional (forward/reverse). All stages have definite time delayed characteristics and two of the stages may also be independently set to IDMT tripping characteristic. Directionality is achieved with negative sequence voltage polarising.

> Phase Overcurrent Four independent stages are available for each phase overcurrent element and the two ground fault elements. The first ground-fault element operates from measured quantities and the second element operates from derived quantities calculated from the three phase currents. Each stage may be selected as non-directional or directional (forward/reverse). All stages have definite time delayed characteristics and two of the stages may also be independently set to IDMT tripping characteristic. The IDMT stages have a programmable reset timer for grading electro-mechanical, to reduce autoreclose dead times and to reduce clearance times where intermittent faults occur.

> RMS Thermal Overload

> Check Synchronism

Thermal overload protection provides both alarm and trip stages. The thermal element may be set with either a single time constant characteristic for the protection of cables or dry transformers, or a dual time constant characteristic to protect oil filled transformers. In the event of loss of auxiliary supply, the thermal state is stored in non-volatile memory.

An adaptive two stage check synchronism function is available for use in conjunction with automatic or manual (re)closure. This function also provides advanced signal indication of system conditions and can for example be used in situations where slip frequency and phase angle for synchro check changes under certain system conditions.

> Under/Overvoltage

> Circuit Breaker Failure Protection

Under/overvoltage protection may be configured to operate from either phase-phase or phase-neutral quantities. Two independent stages with definite time elements are available and one of the stages can also be configured as an inverse characteristic.

Two stage circuit breaker failure protection may be used for tripping upstream circuit breakers and retripping of the local circuit breaker if required. The circuit breaker failure logic may also be initiated from a single pole condition from external devices if required.

> Residual Overvoltage

> Voltage Transformer Supervision

Residual overvoltage protection is available for detecting ground faults in high impedance grounded or isolated systems. The neutral voltage is derived from the three phase voltage inputs. Two independent measuring elements with definite time characteristics are available, one of the elements can also be configured to have an inverse characteristic.

Voltage transformer supervision is provided to detect loss of one, two or three VT signals, providing indication and inhibition of voltage dependent protection elements. An optically isolated input may also be configured to initiate the voltage transformer supervision alarm and blocking when used with MCBs or other external forms of voltage transformer supervision.

Negative sequence overvoltage protection provides either a tripping or an interlocking function, upon detection of unbalanced supply voltages

> Current Transformer Supervision

> Under/Over Frequency

Current transformer supervision is provided to detect loss of phase CT signals and inhibit the operation of current dependent protection elements.

Two independent definite time stages of over frequency and four of under frequency are provided. A time delayed rate of change of frequency element is provided and can be used to accelerate load shedding during severe system disturbances.

> Autoreclose
