Introduction

6F2S1905 (0.41)

GRZ200 distance protection is designed to provide distance protection with control
applications. The GRZ200—intelligent electronic device (IED)—provides you with the
flexibility to meet their application and engineering requirements in addition to offering
excellent performance, the high quality and reliability.

1.1 Protection functions
The IED has a number of protection functions and these functions are being optimized for
transmission or distribution systems. The followings functions, which the IED incorporates
and for which you key their settings with human machine interface (HMI), operate well with
mutual linkage between functions.

[OC]

Directional/non-directional phase over current protection
This function includes four-stages of threshold for faults. This function includes inverse time
and definite time characteristics. Depending upon IED model is the characteristics are
relevant to current and voltage measurement quantities with directional or non-directional
characteristic provided for each stage.

[EF]

Directional/Non-directional phase earth fault protection
This function includes four-stages of threshold for fault protection. The choice of characteristic
is selectable between inverse time, and definite time. Note that the selection of a directional
characteristic is available when the IED model is relevant to both current and voltage
measurement quantities as with the OC function.

[SOTF-OC] Switch on to fault protection
In order to quickly remove a fault which may occur when a faulted line or bus-bar is energized,
the SOTF protection will be operational for a certain period after the circuit breaker closes.
[FS]

Fail-safe protection
The IED is provided with Fail-safe elements which function as a check relay and enhance
security against a fault a power system with week infeed, or prevent a false tripping due to a
signal failure in the protection system.

[VTF] VT failure detection function
When a fault occurs in the secondary circuit of a voltage transformer (VT), voltage dependent
measuring elements may operate incorrectly. The voltage transformer failure detection
function (VTF) avoids such as the incorrect operation. When the VTF detects a VT failure, it

blocks voltage dependent protections instantaneously.
[CTF] CT failure detection function
When there is a fault in the secondary circuit of a current transformer (CT), current
dependent measuring elements may operate incorrectly. The detection function for current
transformer failure (CTF) avoids the above incorrect operation. When the CTF detects a CT
failure, it blocks current dependent protections instantaneously.

6F2S1905 (0.41)

[FL] Single-end fault locator
When a fault is detected, fault locator can determine distance between the IED and the fault
point.
[ARC] Auto-re-close function
After the IED trips a circuit breaker (CB) due to a fault on the Line, the automatic re-close
function can close the CB so as to reenergize the power.
[VCHK] Voltage check for auto-re-close function
This function is used in corporation with the function of auto-re-close (ARC). The VCHK
checks voltage and frequency differences between a Bus-bar and Lines, and permits the ARC
the operation.

1.2 Control
The IED provides control functions for circuit breakers and isolators, other switchgear and
transformers. These functions, are operated via the HMI, or other functions, are also
available such as automatic sequence control, interlocking operation and manual override
operation.
[LRST] Trip LED reset function
When the LED is continuously illuminated following the completion of a trip operation, it can

be turned off using LRST.
[L/R]

Remote/Local control function
When control of the object device is required, this function allows the selection of the control
command for either local or remote, (dispatch site/control centre) operation.

[GCNT] General pulse counter function
This function can observe a signal, for example the output of a PLC function and counts the
number of pulses for the signal. The total number of pulses counted is recorded.
[MDCTRL] Mode control function
This function enables an interface for test function block (TSET-FB). With this interface, a
mode change command is made within the IED for the TEST-FB.

1.3 Monitoring and metering functions
The monitoring and metering functions, using the HMI, display status, settings, data and
others. The user can also see information on a PC with “GR-series Toshiba IED Engineering
and Monitoring Software (GR-TIEMS)” at local and remote end both.

Monitoring function:
This function supervises status of protection functions, and displays power system quantities.
It also shows failure information in the CT and VT.

Fault record function:
Such function records the state of a fault when the trip command is issued. It also memorizes

the fault data. The user can see, with the IED screen, these data with additional information:
date & time, fault phase, tripping phase, tripping mode, fault location, operating mode and
power system quantities.

Event record function:
Such function provides recording feature that memories any event occurred in the IED.

Disturbance record function:
Disturbance record is triggered by fault detection. The user can see the waveform recorded by
this function using GR-TIEMS.

1.4 Hardware overview
A human machine interface (HMI) consisting of a screen, indication lights, operation and
function keys, monitoring jacks and a USB connector are provided in the IED. The IED has
signal terminals at the rear. Input and output module circuits are provided for these signals.

HMI features:
