ELECTRICAL TESTING
For 14KV 240KV GENERATORS
TECHNICAL SPECIFICATIONS

SCOPE

Electrical Testing. To perform Testing as required
and as requested by Seattle City Light, to include providing highly skilled Relay Technicians to perform
final programming and setpoint modifications to new protective relay
installations along with performing quality control (QC) checks of the
associated circitry. Perform routine testing procedures on 3-phase 14KV
240KV main generator step-up transformers and 240KV power circuit
breakers including power fractor (Doble), timing and turn-to-turn ratio
testing and ductor and relay maintenance and testings on a periodic
basis.

The following Section Four is an excerpt from Boundary Generators/Lines
51-54 Microprocessor Relays Manual. It is included here for the purposes
of identifying the testing and commissioning procedures required of
the successful proposer upon issuance of a vendor contract. Each proposer
is required by this specification to acknowledge receipt of Section
Four and acknowledgement that they know and understand the procedures
required by the City of Seattle for Electrical Testing.

Test and Commissioning Procedures

This test procedure is intended for use by trained
electrical workers and protective relay test personnel.

It is assumed herein that journey level qualified
persons will read and use this test procedure.

It is not intended that this document be used as
a training guide for those inexperienced in the work. The terminology
and information presented is not sufficiently detailed for that purpose.

Table of Drawings

The table below lists all drawings required for performing
testing and commissioning of the relay system. These drawings will be
referred to by item number from the table
in the text.

The drawings listed are for Generators and Lines 51-54. Other than
