1 Introduction

The FTL Test Block

The FTL is a test block for interfacing substation devices (protection relays, fault

recorders, revenue meters, . . . ) to the voltage and current transformers and to other

equipment on the system side of a power grid.

The FTL Test Block uses Disconnect Pins to isolate the substation devices from the

system side equipment. Once isolated, secondary injection can be performed using

banana jacks on the front side of the Test Block.

Key Features

•Finger-safe Test Block and Disconnect Pins increase safety during testing.

•Disconnect Pins are keyed to the corresponding parts of the Test Blocks, pre-

venting mistakes and errors during test.

•Extremely low internal resistance (<2 mΩ) helps reduce heat inside cabinets

and panels.

•Available in 8, 10, 12, 14, 16, 18 or 20 pole conﬁgurations.

Applicable Models

Information in this document applies to all FTL Test Blocks manufactured after May

2011.

Unpacking

Unpack the product carefully and make sure that all pertinent parts like dust covers

and screws are put aside so they will not be lost.

Check the contents against the packing list. If any of the contents listed are missing,

please contact SECUCONTROL immediately (see contact information at the rear cover

of this manual).

1. INTRODUCTION

Examine the product for any shipping damage. If the product is damaged, notify

the shipping company without delay. Only the consignee (the person or company

receiving the unit) can ﬁle a claim against the carrier for shipping damage.

Part Number and Manufacturing Date Location

Part number and manufacturing date are stated on a label on the right side of the Test

Block.

Safety Symbols

The following symbols are located on different parts of the equipment and in this

manual:

Paragraphs marked with this symbol contain information which,

if not properly followed, may cause damage to the equipment

and/or installation.

Paragraphs marked with this symbol contain information which,

if not properly followed, may cause personal injury or even

death.

General Safety Instructions

Installation and operation of the products described in this manual is only to be per-

formed by personnel that has been trained or is knowledgeable in substation protec-

tion, automation and control.

This instruction manual is an integral part of the scope of delivery and provides basic

instructions for installation and operation of the equipment here described. Shall ad-

ditional information be needed, please contact SECUCONTROL at any of the addresses

provided on the rear cover of this document.

Do not disassemble the Test Block. Correct alignment of internal parts is critical in

order to provide insulation and arch-avoidance.

The warranty will be void if the Test Block is disassembled (or otherwise handled

inappropriately). SECUCONTROL does not assume responsibility for any damages

arising out of mishandling of our products, including test blocks that have been disas-

sembled by parties other than SecuControl.

2 Principle of Operation

Closed Circuit

In the resting state the contacts of the FTL Test Block are

closed. In this situation, the signals from the system side

of the installation (side A) are connected to the measuring

and protection devices (side B).

Open Circuit

To open the Test Block’s contacts, the disconnect pins are

moved from the parking position to the test position. In

this situation, the devices on the B-side are insulated from

the installation side.

Signal Injection

With the disconnect pins in the test position, signal injec-

tion can be performed using the banana jacks on the front

side of the Test Block.
