Section 6: SPDU Guide Specifications

62 SPDU Technical Handbook

l. K Factor

m. Crest Factor

n. Discrete Input and Output Status

o. Analog Input Reading

p. Custom: User programmable display of any combination of

up to seven metered values

2. All three phases of three-phase parameters must be displayed simultaneously. All voltage

and current parameters must be monitored using true RMS measurements.

E. Premium-level Alarm Annunciation

1. The Premium-level monitoring system must also supervise and annunciate the following:

a. Output Over Voltage: Line-to-line for all three phases

b. Output Over Voltage: Line-to-neutral for all three phases

c. Output Under Voltage: Line-to-line for all three phases

d. Output Under Voltage: Line-to-neutral for all three phases

e. Maximum Thresholds:

1.) Current: All three phases, neutral and ground

2.) Voltage: Neutral to ground

3.) System Power: Watts, kVA

4.) Frequency

5.) % THD

f. Minimum Thresholds:

1.) Current: All three phases

2.) System Power: Watts, kVA

3.) Frequency

g. Voltage Phase Unbalance: Line-to-line for all three phases

h. Voltage Phase Unbalance: Line-to-neutral for all three phases

i. Current Phase Unbalance: All three phases

j. Discrete Input Energized: All discrete inputs

k. Reverse Sequence Error

2. All Alarms must be stored in non-volatile memory until manually reset.

F. Premium-level Custom Alarm Annunciation

1. The Premium-level monitoring system must also be capable of providing up to four (4)

Form C (NO/NC) relay contact enclosure outputs.

2. These relays must be independently programmable to actuate one event condition and/or a

combination of metered event conditions.
