TIS performance graphs below show real-time results when (3) XL Modules are turned ON and OFF when connected to a 500 HP Motor. Figure 1 shows meter recording
station. Figure 2 shows (3) XL-3D-480V modules connected to a subpanel which connects in parallel to Motor Drive (not shown). Figure 3 shows CT and voltage meter
test probes connected to main conductors in an Isolation Transformer on the line side of Motor Drive. Figure 4 shows 500 HP Motor. XL Subpanel and XL modules are
located 20’ upstream of 500 HP Motor and 200’ downstream of the 500A main breaker located in Main Distribution Panel (MDP) in electrical room.

The product of the root-mean-square (rms) of Voltage and
Current. When impedance is pure resistance, Apparent Power 3 3303,00,00000
equals Real Power (kW). But when reactance (inductive loads
like motors) exists on the circuit, Apparent Power is greater 3 2352,50,00000
than Real Power because it contains kVAR demand from
inductive loads requiring Reactive Power (kVAR). 3 2302,00,00000
TIS TEST RESULTS (500 HP MOTOR)
Test results show an average REDUCTION in Apparent Power 31 531,50,00000
of 60.8 kVA or 19.3%. XL Systems reduce Apparent Power
(kVA) which corresponds to reductions in Reactive Demand 31 031,00,00000
(kVAR).
