DOE-HDBK-1132-99

distribution system is a single-point impedance grounded system, installation of a

static wire system with multiple grounding and surge arresters on all three

phases at prescribed intervals should be considered. Surge arresters should

also be installed on pad-mounted distribution transformers at their primary

terminals.

When open wire lines supplying power to high-reliability loads are extended

outside process areas that require high reliability, installation of automatic

reclosers should be considered outside the high reliability areas and properly

coordinated to limit supply interruptions.

2.3

Emergency Preparedness Facilities . Reliability, flexibility for operations, and safety of

personnel should be considered in the design of electrical distribution systems for

emergency preparedness facilities. Standby power sources capable of supporting full

operation of emergency loads for a minimum of 24 hours or for a period specified by the

design authority should be included in the design basis. Special-purpose receptacles

used to power equipment should have permanent labels to mark voltage, amperage,

number of phases, power source, etc.

Telecommunication Facilities . Design of power distribution to essential equipment

should consider uninterruptible power sources or emergency backup power sources.

Design coordination with equipment system specialists and DOE security personnel is

essential to determine the load demand. A plug-in connection to a portable generator

should be considered.

Automated Data Processing (ADP) Centers . Guidelines on electrical power for ADP

installations are provided in Federal Information Processing Standards Publication, FIPS

PUB 94.

Radio Control Centers . In determining power supply requirements, it is reasonable to

assume that all the transmitters are keyed simultaneously while associated receivers

and other equipment and building services are in operation.
