APPLICATION & DUTY
Where MKTBBZ fits
MKTBBZ is an automatic medium-voltage reactive-power compensation arrangement using switched capacitor groups. It follows reactive demand through a selected stepping scheme. Capacitor capacity, reactors and protection must be coordinated with the network and its harmonic conditions.
APPLICATION / 02
Variable reactive demand
For installations where staged capacitor switching is selected to follow changing load requirements.
PRODUCT ENGINEERING
Construction & operating functions
DETAIL / 01
Grouped capacitor switching
Capacitor groups are switched in stages rather than treated as one undivided bank. Stage allocation affects the available compensation steps.
DETAIL / 02
Reactive-power control
The controller selects switching according to the agreed control objective and measured system condition. Settings must be coordinated with the installation.
DETAIL / 03
Reactor coordination
Reactors are selected with regard to switching inrush and the network harmonic environment. Their specification requires system information rather than a generic percentage assumption.
DETAIL / 04
Protection arrangement
Bank connection and protection functions must match the selected capacitor arrangement. The required protection scheme belongs in the technical schedule.
