Existing Electrical Conditions and Building Load Summary

This report provides a detailed explanation of the existing electrical system in Redifer Commons.The loads presently needing electric power are lighting equipment, receptacles, mechanical equipment, and food service equipment. The lighting loads were calculated using the General Loads by Occupancy in the 2002 National Electric Code, while the receptacle loads were calculated by careful analysisof the electrical power drawings and panelboards. Load schedules were provided to calculate the loads for the mechanical and food service equipment. Once these individual loads were found and proper demand factors from the NEC were applied, the load on each distribution panel was determined.

The next step was to determine whether the existing transformer, distribution panels, and feeders were sized accordingly. Using the total loads I calculated, I found that all components of the existing system were sized appropriately. The system also is extremely oversized for future growth purposes. This is often common practice in food service buildings.

Finally, a utility rate structure was determined. Since Redifer Commons is part of thePennsylvania State University, the utility rate is based on Pennsylvania Retail Tariff No.37 under Allegheny Power (formerly West Penn Power) which governs the entire University. The rates, terms and conditions of this plan can be found abbreviated within my report, and complete on my website following this report. The actual demand for the addition can not be done at this time because a submeter has not yet been installed. The submeter, owned by Penn State used to bill each section of the campus, reads demand only on the existing section of the building. A new submeter is expected to be installed very soon.

System Narrative

General Overview of Electric System Redifer Commons uses a radial system to supply electricity to the building. The transformer is internal and is located in the basement of the commons, powered by Allegheny Power. This transformer, which is liquid filled, with silicon oil to be exact, is connected in a delta-wye configuration, stepping down from 4160V supplied from the utility, to 208Y/120V which is then distributed throughout the building. The transformer is rated for 966 KV. The power from the transformer is then sent to two main distribution panels. The first distribution panel (SDP1) is rated for 1200A, while the second (SDP2) is rated at 600A. These two distribution panels circulate the power to many panelboards located throughout the building. The panelboards used are 208Y/120V, 3 phase, 4 wire or 240/120V, single phase, 3 wire and are rated at 125A or 225A. Emergency Power Systems Emergency power is provided by a generator and is controlled by a 260A, 220V, single phase, 3 wire Automatic transfer switch. This ATS is connected to Panelboard ‘NE1’ which runs on normal electric unless there is some sort of power outage. The generator comes on if it notices the normal electric is no longer running, forcing the switch to cross over to the emergency power which is distributed from an existing load center in the main electrical room. Overcurrent Protection Circuit breakers are used throughout the building as overcurrent protection, and specifically main lug only circuit breakers on the main distribution panels. These circuit breakers have been called out for the large components on the single line diagram. The panelboards contain mostly 20A circuit breakers with some 50A and 30A occurrences. Typical Lighting System Linear fluorescent fixtures and recessed compact fluorescent lighting fixtures are used most frequently throughout the building for general lighting applications. Many decorative low voltage halogen and compact fluorescent fixtures are used in the dining area as well. The exterior lighting is done mostly using ceramic metal halide. All lighting operates on 120 V. Power Factor Correction There are no capacitors used in Redifer Commons at this time to correct a poor power factor. Once submetering is installed to the addition, an analysis will occur to determine if there needs to be power factor correction.

Important Design Requirements There are a couple important design requirements that were taken into consideration with the electrical design of Redifer Commons. The first deals with the large capacity already present on the existing switchgear. There was very little spare capacity left on the switchboard and the University budget did not allow for a service upgrade, so there needed to be careful considerations when choosing the electrical, lighting and mechanical equipment. They needed to be sure that they did not exceed the available capacity. Besides this concern with the old switchgear, the reliability of the entire existing system was not an issue since the University underground distribution system has proved to be fairly reliable. The last issue concerns voltage drop. Voltage drop is always an issue, especially with 208/120V, 3 phase, 4 wire systems. Voltage drop calculations are required for panel feeders longer than 100 linear feet and branch circuit wiring greater than 60 linear feet. To be safe the electrical engineer on the job started calculating voltage drop at 60 feet just to be safe. Location of Equipment

Lighting Table In the table below you will find all the primary lamps and ballasts used in the Redifer Commons addition and renovation. Specific lamps and ballasts were not specified in the spec, so assumptions were made here based on the general requirements set forth in the electrical section of the spec. These requirements can be found in Tech Assignment 1. Also, since specific ballasts were not specified, a ballast factor of 1.0 was assumed for Tech Assignment 1. For the purpose of this technical assignment, I searched for compatible ballasts to find the appropriate power factors and input watts.

Receptacle Loads The demand factors used below for duplex and double duplex receptacles consider the first 10 KVA at 100% demand and the remaining at 50% demand. The two single phase receptacles on SDP1 supply power to kitchen equipment and serve 4 pieces of equipment which were not listed on the food service schedule (the remaining kitchen loads can be found in the food service loads table), so a demand factor from Table 220.20 in the 2002 National Electric Code was used.

Feeder Sizes to Main Distribution Panels SDP1-

The feeder for this main distribution panel is (4) 600 KCMIL & (1) 3/0 in 3-4” Conduit protected by a 1200A circuit breaker

Since there are 3 runs of conduit this feeder uses parallel circuits. 600 KCMIL has an allowable ampacity of 420 A, so with 3 runs you are allowed 1260A of current total on

this feeder With my calculations: I=VA/(√3(V))= (288,400VA) /(√3(208V))= 800.5A The existing breaker and feeder have been yet again oversized for future growth.

SDP2-

The feeder for this main distribution panel is (4) 600 KCMIL & (1) 4/0 in 4-4” Conduit protected by a 600A circuit breaker

Since there are 4 runs of conduit this feeder uses parallel circuits. 600 KCMIL has an allowable ampacity of 420 A, so with 4 runs you are allowed 1680A of current total on

this feeder With my calculations: I=VA/(√3(V))= (170,110VA) /(√3(208V))= 472.2A The existing breaker and feeder have been yet again oversized for future growth.

Transformer-

Rated at 966 KVA> 458.55 KVA so transformer provides sufficient protection Standard sizing in the field sizes a transformer to about 50% of its capacity, and the value I calculated is

48% of the capacity.

Utility Rate Structure The utility supplying energy to Redifer Commons is Allegheny Power (West Penn Power). The rate structure used is Pennsylvania Retail Tariff No.37 and is described below and was found at www.alleghenypower.com. With all charges and sales tax the total rate ends up being around $0.04/KWH. Metering can not be done at this time for the addition, but the existing meter on Redifer Commons read 115KW demand for the month of September. NOTE: THIS VALUE DOES NOT INCLUDE THE ADDITION. The demand only a year ago was 187KW, so it can easily be seen that many improvements were made in the electrical system as a whole. One huge change was bringing the entire chilled water system for the air conditioning out of the building. This entire file for the Pennsylvania Retail Tariff No.37 can be found following this report on my website.
