Learn how field equipment works by experimenting
Simulators that run in your browser, nothing to install: electrical equipment, pumps, production processes, maintenance with SAP and safety. To understand what happens inside the equipment we maintain in the field every day, and to practice operating it and working safely. The PID simulator is fully in English; the others are in Spanish for now and are being translated one by one.
NEWIndustrial electricity
Ohm's law, series and parallel with light bulbs, troubleshooting with a multimeter and clamp meter, AC, three-phase, cables and protection, motor control with contactors and the five golden rules of electrical safety.
Open simulator →
NEWThree-phase separators
Stokes' law with moving droplets, a three-phase separator in operation with oil and water specs, PIC/LIC loops with slugs and failures, SDV and PSV, and sizing by Souders-Brown and retention time.
Open simulator →
NEWCircuit breaker protection settings
Turn the dials of an LSIG trip unit (Ir, tr, Isd, tsd, Ii, Ig, tg), see the time-current curve against the load, motor starting and cable, check selectivity and ground fault, and run injection tests.
Open simulator →
NEWSolar photovoltaic energy
Panel curve and MPPT, string design against the inverter, hour-by-hour self-consumption, batteries during a power outage, real bill savings (Colombian CREG 174 rules) and string fuses.
Open simulator →
NEWGrounding systems
Step and touch voltages, Wenner soil resistivity, design of rods, counterpoises and grids (Colombian RETIE), fall-of-potential method (62 %) and clamp-on method.
Open simulator →
NEWPID control and loop tuning
ON/OFF vs PID, P, I and D actions, step test and process identification, Ziegler-Nichols, lambda, SIMC and relay autotuning, windup, sticky valves and pump intake pressure (PIP) control on electric submersible pumps. Fully in English.
Open simulator →
NEWPumps: curves and operation
Power and motor, pump and system curves, BEP zone, valve vs. VFD control, NPSH and cavitation, series and parallel, positive displacement (triplex, PCP, gear, screw) and electric submersible pumping.
Open simulator →
NEWTransformer testing
Turns ratio (TTR) per tap and excitation current, vector group, winding resistance corrected to 75 °C, and insulation with polarization index. Find shorted turns and loose tap-changer contacts.
Open simulator →
NEWVFDs: power, control, boards and testing
Rectifier and precharge, DC bus and braking, IGBTs, dead time and desaturation, PWM, V/f and vector control, a test bench with a multimeter (diodes and IGBTs) and boards with an oscilloscope, with hidden faults to diagnose.
Open simulator →
AVAILABLEMotor starting
Compare direct-on-line, star-delta, soft starter and VFD with your motor and load, and preselect the breaker, overload relay and conductor (Colombian NTC 2050, based on the NEC).
Open simulator →
AVAILABLEPower generation
How a generator set of any brand works: poles and speed, excitation families (PMG, self-excited, AREP), voltage regulator, governor, P-Q capability curve and controller protections.
Open simulator →
AVAILABLEGenerator synchronizing
A practical 7-stage guide: synchronize manually and automatically, share kW and kVAr, cause faults and learn to read the event log. With DSE, ComAp and DEIF.
Open simulator →
AVAILABLEWork at height
Would your worker hit the ground? Calculate the fall clearance, see the swing-fall effect, inspect a harness and decide whether to approve a work permit.
Open simulator →
AVAILABLEPower quality
Power factor with phasors and a PF meter, load types, hour-by-hour reactive energy charges, capacitor bank sizing, resonance and harmonics per IEEE 519.
Open simulator →
AVAILABLESAP PM for maintenance
An S/4HANA-style launchpad and 23 real transactions: notifications and work orders with company order types, confirmations, technical completion, purchasing and stores, measuring points, preventive maintenance and MTTR/MTBF, with 12 guided exercises.
Open simulator →See in seconds what takes hours of measurements in the field.
Understand why equipment behaves the way it does before it fails.
We develop them from real industrial maintenance experience.
Does your real equipment have a fault?
We troubleshoot VFDs, motors, generators and pumping systems in the field.
