marked with essential operating data, including PCB classification.
Nameplate shall meet ANSI standard C57.15.
4.4.14.2 The nameplate shall show the type of material in coils.
4.4.15 Oil Preservation
4.4.15.1 A sealed tank system shall be standard on all regulators.
4.4.15.2 A sealed tank system is one in which the interior of the regulator will be
sealed from the atmosphere throughout its top oil temperature range, and in
which the gas plus the oil volume remain constant. The regulator will

Page 18
remain effectively sealed throughout a top oil temperature range from minus
5C to plus 105 C provided the initial level has been properly adjusted.
4.4.16 Motor Capacitor
The voltage regulator shall have the tap changer motor capacitor mounted inside the
control enclosure for ease of replacement.
4.5.0
Quality Program Requirements
4.5.1 General Requirements
Regulators addressed by this specification are subject to a quality program which
establishes requirements to assure that the regulators provided by the vendor will
comply with Industry Standards or this specification.
4.6.1
Regulator Bid Evaluation
4.6.1 Bids submitted for all schedules shall be evaluated for ACost of Ownership@utilizing
initial cost, regulator losses, and the cost of financing. The formula is as follows:
ACost of Ownership@ = (Unit Cost) + (Core Losses x A) + (Winding Losses x B)
The cost of losses will be evaluated using the following watt charge:
A. Core Loss (N.L) = $7.80 / watt
B. Winding Loss (L.L.) = $2.10 / watt
4.6.2 Loss values utilized in evaluation of regulators will be the average of the
respective losses at the 15 raise and the 16 raise position.
4.6.3 The City reserves the right to change at any time the no-load loss and winding loss
charge given above insofar as these values are used to evaluate bids.
4.6.4 Failure to meet guaranteed losses shall result in an adjustment of the purchase
price difference in guaranteed and the actual values multiplied by a penalty factor
of three (3) times the cost of losses. If one type of loss exceeds guaranteed values
and the other is less than guaranteed values, then the evaluation of both may
determine the amount of the adjustment. However, IN NO CASE, shall the
adjustment factor under this provision result in the net price increase to the City.
4.7.0 Other
4.7.1 All exterior nuts, bolts and hardware shall be of a corrosive resistive material.
4.7.2 The liquid supplied in these regulators shall be ANSI type II non-PCB type, as
defined by ASTM-D-3487 Federal Regulation 40 CFR Part 761, latest revision. The
liquid contained in these regulators shall be identified as a non-PCB type containing
FB # PS-ELSS-08-18-2015
Page 19
less than 1 ppm. The data shall be on the nameplate on the regulator and on a
separate ANon-PCB@ label, no larger than 3 inches by 3 inches, affixed to the regulator
tank directly below the inside nameplate. A copy of the oil test report or oil
certificate shall be furnished with each regulator delivered and shall include the
regulator serial number listed.
4.7.3 All regulators shall be delivered in a flat bed or open top transport. Regulators
arriving in a closed top trailer will not be accepted.
