Getting this OID will return the phase/bank load state.
phaseLoadNormal(1) indicates that the phase/bank is
operating properly within the rPDULoadConfigLowLoadThreshold
and rPDULoadConfigNearOverloadThreshold OID values.
phaseLoadLow(2) indicates that the phase/bank load has
dropped below the rPDULoadConfigLowLoadThreshold OID value.
An SNMP trap will occur when this state is entered or cleared.
phaseLoadNearOverload(3) indicates that the phase/bank load
is greater than or equal to the
rPDULoadConfigNearOverloadThreshold OID value.
An SNMP trap will occur when this state is entered or cleared.
phaseLoadOverload(4) indicates that the phase/bank load is
greater than or equal to the rPDULoadConfigOverloadThreshold
OID value.
An SNMP trap will occur when this state is entered or cleared.
