PowerCalc Pro

PowerCalc Pro is a field notebook for comparing a substation scheme. Four tabs take one job from the diagram to the curves: System, Power Flow, Fault, Protection. The interface is English. Data stays on this device. Change a load, a fault bus, or a relay setting, and power flow, fault current, and operating time update. This is a record-and-compare tool. The diagram, flow, and curves come from the network you enter. The phone does not connect to a control system, pass or fail a grid, or issue a signed calculation. 01 System Open the system diagram (sample DEMO · 110kV Substation PC-01, code SYS-110-01). Read the 110 kV and 10 kV single-line, including GRID-01, BUS-110A, BUS-110B, T1, T2, and four feeders. Tap an asset, drag a node, edit parameters, and open the project workspace. 02 Power Flow Open power flow. Run the solution, scale the load, and switch the voltage and power overlay. Open a bus result, solver setup, and scenario comparison. 03 Fault Open the fault lab. Choose a fault type and bus, then calculate the short-circuit current. Open the reference waveform, source contribution, and equipment comparison. 04 Protection Open protection coordination. Move the cursor on the time-current chart and read upstream, local, and downstream operating times. Open protection devices, the curve inspector, and the local calculation book. For engineers who need a scheme-side comparison. Flow, fault current, and operating time are estimates. They do not replace a system study, a relay setting sheet, or a signed design.
