Cat XLM Switchgear

Cat XLM Switchgear

Overview

XLM switchgear is used when the generators are paralleled with a normal utility (or multiple utility) power source(s). SLM switchgear allows closed transition, softloading and unloading from utility and peak shaving capability where generators operate continuously in parallel with the utility.

Specifications

Units: 
Configuration Configurable PLC based switchgear capable of controlling and monitoring multiple generator sets, tie, utility and load breakers for utility paralleling applications
Modes of Operation Emergency Standby, Utility Import/Export, Peak shaving, and base load operations with redundant controls and components. Closed transition to/from generator power
Application LV and MV ( 208V - 38 kV
