Load Flow Analysis
Verifies voltage profiles, equipment loading, and capacity headroom across utility, generator, power factor correction and UPS operating modes.
Short Circuit Analysis
Confirms interrupting and withstand ratings of every breaker, switchgear lineup, and busway.
Protection Coordination
Achieves selective tripping so a downstream fault never cascades into a whole-room outage.
Arc Flash Analysis (AC and DC)
Incident energy calculation, PPE category assignment, and equipment labeling for safe live maintenance.
Motor Starting Analysis
Evaluates voltage dip from chiller and CRAC motor inrush, including start against generator source.
Transient Stability Analysis
Evaluates frequency and voltage response to generator trips, transformer energization, and load trips, then reviews load shedding in ETAP.
Harmonic Analysis
Includes on-site testing at the client site to obtain Power Quality Data.
