IHT Technical Reference
Setting the Load Values
By default, the IHT allows you to set the load as a percentage of the
supply on test from 0% up to a maximum of 120%. The actual load
applied is based on the supply on test and load bank settings made on
the Setting 1-2 and Settings 2-2 Pages.
However, by pressing F3 (SELECT) you can choose between setting
the load using kVA, Power Factor or Percentage load values (If a
resistive-only load bank is used, then the selection will be percentage
load and kW only).
Power factor can be set between 0.00 and 1.00 cos
Φ
on the IHT (most
generators are rated at 0.8 cos
Φ
). However, non-unity power factor
values are dependant on the load bank capacity and the supply size.
Adjust the Load Percentage
Use the + or – keys to set the
percentage of load to be applied.
Adjust kVA
Use the + or – keys to set the kVA
value of the load to be applied.
Select Power factor
Use the + or – keys to set the
power factor of the load to be
applied.
