Section 1 Introduction

1.1 This manual

GUID-AB423A30-13C2-46AF-B7FE-A73BB425EB5F v18

The application manual contains application descriptions and setting guidelines

sorted per function. The manual can be used to find out when and for what purpose

a typical protection function can be used. The manual can also provide assistance

for calculating settings.

1.2 Intended audience

GUID-C9B8127F-5748-4BEA-9E4F-CC762FE28A3A v11

This manual addresses the protection and control engineer responsible for

planning, pre-engineering and engineering.

The protection and control engineer must be experienced in electrical power

engineering and have knowledge of related technology, such as protection schemes

and communication principles.

Figure 1: The intended use of manuals throughout the product lifecycle

The engineering manual contains instructions on how to engineer the IEDs using

the various tools available within the PCM600 software. The manual provides

instructions on how to set up a PCM600 project and insert IEDs to the project

structure. The manual also recommends a sequence for the engineering of

protection and control functions, LHMI functions as well as communication

engineering for IEC 60870-5-103, IEC 61850, DNP3, LON and SPA.

The installation manual contains instructions on how to install the IED. The

manual provides procedures for mechanical and electrical installation. The chapters

are organized in the chronological order in which the IED should be installed.

The commissioning manual contains instructions on how to commission the IED.

The manual can also be used by system engineers and maintenance personnel for

assistance during the testing phase. The manual provides procedures for the

checking of external circuitry and energizing the IED, parameter setting and

configuration as well as verifying settings by secondary injection. The manual
