Distribution Analysis (CYMDIST)	To perform several types of analysis on balanced or unbalanced three-phase, two-phase and single-phase systems that are operated in radial, looped or meshed configurations. This includes per-phase voltage drop and power flow analysis, fault calculations (fault flows and fault voltages), protective device coordination (by interfacing with CYMTCC), optimal capacitor placement and sizing, load balancing and load allocation/estimation. The additional modules listed below require CYMDIST to run.
Advanced Project Manager	Supports the collaborative and detailed preparation of a project that consists in modifications to the network with related simulations.
Network Forecaster	To view, modify and create time-dependent projects (using the CYME Advanced Project Manager) consisting in modifications to the network such as the addition of any load at a given date, change/replacement of power transformers within a substation, a rephasing/reconductoring project, network switching or reconfiguration, etc.
