1.6 SYSTEM DESCRIPTION

1.6.1 System Requirements

The metering and reading system, consisting of LonWorks WNC WattNode Electric Meter and ILON 600 IP/Server will be used to record the electricity consumption and other values as described in the sections that follow and as shown on the drawings.

1.6.2 Selection Criteria

Metering components are part of a system that includes the physical meter data recorder function and communications (modern) method. Every building site identified shall include sufficient metering components to measure the electrical parameters identified and to store and communicate the values as required in the following sections. Contractor shall verify that the metering system installed on any building site is compatible with the facility-wide communication and meter-reading protocol system.

a. The purpose of the following specifications is to achieve meter equipment compatibility with the

Army metering program pursuant to Public Law 109-58, Section 103 of the Energy Policy Act of

2005. The intent is for all advanced meters to report their data to an installation-centric energy reporting and management system such as a utility monitoring and control system (UMCS). The advanced meters must provide data at least daily and measure at least hourly consumption of electricity. The means for meter data transmission using open-protocols such as ANSUCEA

709.1 b (LonTalk) and over low cost transport media (ILAN). These specifications provide the needed support of data transmission system alternatives in addition to meeting the minimum standards for energy consumption data recording and reporting. The meters will be capable of integrating with the Army’s communication networks supported by Network Enterprise Command

(NEC).

PART 2 PRODUCTS

2.1 Current Transformers (CT)

Shall have an output of 333mv as required for the Wattnode of Model # type WNC-XX-XXX-FT10-L and sized as follows. Unless otherwise indicated, bar, wound, or window-type transformers are acceptable;

and except for window-type units installed over insulated buses, transformers shall have a BIL rating consistent with the rated BIL of the associated switchgear or electric power apparatus bushings, buses or conductors.

Current transformers shall have the indicated ratios. The continuous thermal-current rating factor (TCR) shall not be less than 2.0. Other thermal and mechanical ratings of current transformers and their primary leads shall be coordinated with the design of the circuit breaker and shall be not less than the momentary rating of the associated circuit breaker.

Circuit protectors shall be provided across secondary leads when a form meter is used of the current transformers to prevent the accident open-circuiting of the transformers while energized.

Each terminal of each current transformer when form meters or used shall be connected to a short-circuiting terminal block in the circuit interrupting mechanism cabinet, power transformer terminal cabinet, and in the associated instrument and relay cabinets. CT used with the Advanced Wattnode meter does not require TCR or CT shorting circuit terminal blocks. The output for the Wattnode CT’s is a standard 333mv.

CT Selection has two main criterions:

1. CT shall be sized so that 10-percent of the rated CT is equal to or less than the minimum load of the load being metered. While 10-11 percent is for electromagnetic metering equipment, 5-percent is for electronic metering equipment.

2. CT shall be sized so that the rated CT (with TCR) is slightly above the maximum load being metered.

3. Selection examples (all using TRF of 2.0, 3 phase configuration):

Provide butyl-molded, window-type current transformers mounted on the transformer low-voltage bushings. Route current transformer leads in a location as remote as possible from the power transformer secondary cables to permit current measurements to be taken with hook-on-ammeters.

NOTE: See TM 5-811-I/AF AFJMAN 32-1080 for guidance regarding voltage transformers. Minimum standard potential transformer accuracies for metal-clad switchgear are not listed in ANSI C37.20.2.

Accuracy classes as listed in IEEE C57.13 are 0.3, 0.6, and 1.2. Standard burdens for each accuracy class are W, X, Y, ZZ, and M. The designer should check the burdens connected to determine the actual accuracy class and burden required. In general, ANSI C12.11 requires 0.3 accuracy class for up to Y burdens, except for voltages of 5 kV and below. Where metering potential transformers are provided, a

0.3 accuracy class should be specified, if available for the voltage rating and burden needed. Voltage transformers shall have indicated ratios. Units shall have an accuracy class rating of 0.3. Voltage transformers shall be of the draw out type having current-limiting fuses in both primary and secondary circuits.
