1 Functions and Applications

1.1 Overview
PCS-902S protect overhead and underground lines, feeders and cables on all voltage levels with
highest selectivity possible. The large number of protective and automatic functions available
permits their utilization in all areas of line protection. The devices contain all important auxiliary
functions that are necessary today for safe network operation. This includes control, measurement
and monitoring functions. The large number of communication interfaces and communication
protocols satisfies the requirements of communication-based selective protection and of
automated operation. Their modular structure permits line protection devices always to be adapted
flexibly to the individual requirements.
The functional overview of the device is shown in Figure 1.1-1.

Figure 1.1-1 Functional overview of PCS-902S

PCS-902S is a high-speed transmission line distance relay featuring single-pole and three-pole
tripping and reclosing with synchronism check. The device features extensive metering and data
recording including high-resolution data capture and reporting. PCS-902S features expanded

control equation programming for easy and flexible implementation of custom protection and
control schemes.
A simple and robust hardware design features efficient digital signal processing. Combined with
extensive self-testing, these features provide device reliability and enhance relay availability.
PCS-902S can be configured to support single circuit breaker application or double circuit
breakers application by PCS-Studio. If the device is applied to double circuit breakers mode, all

2.2 Selection Information
A MOT serial code consists of several bits, and the specific meaning of each bit is as below.

2.2.1 Device Type
For a specific device, the device type is fixed, such as PCS-902S, so it is not need to be chosen.

2.2.2 Application Scenario (U Field)
The corresponding application scenarios are selected according to the actual protected objects by
the device. Only one kind of application is available, so it is chosen as "2 terminal line" fixedly.

2.2.4 Firmware Version (R Field)
The firmware version is used to select required program version. If there is no special version
requirement, the latest version can be chosen, i.e., “Latest version”. Otherwise, the specified
version can be chosen.

2.2.5 Software Functions (S Field)
The software functions are determined by four parts: "Software", "Language", "Protocol" and
"Sampling mode".
1.

Software

The option is used to select the required protection functions, which is used in conjunction with the
