Installing a servo-stabilizer in Woodland Guest House

A servo-stabilizer installed Woodland Guest House lighting load.

Date: 24th February 2012 Capacity: 30 KVA Company: Muskaan’s

History: Servo was initially in line but after

loading AC’s it was bye-passed. Load Analysis of connected load was

done.

Reason: Installing AC’s in Woodland-boys

could result in the over-loading servo, hence resulting in a flash.

Lighting load is under 30 KVA

A new cable was dug in and geysers and AC’s would be fed by it. This cable would not be under Servo-stabilizer’s load. Now only the lighting load of Woodland would be fed under a stabilizer.
