BIG Problem:

XXX Towers Sector - 56, Gurgaon 122011 is a condomonium of 19 high rise buildings with 1000 flats. They have DG sets AMF panels for power backup. But unfortunately when HUDA [grid] power supply is resumed, the phase sequence of the supply is often revered and all their three phase motors get affected badly.

Simple Solution:Use automatic phase sequence correction panel from Hanut India.

Hulasi has received several repeat orders from an MNC for supply of Automatic Phase Sequence Corrector panels [APSC] for use with their large 3 phase industrial UPS s.

Hulasi APSC panel vs the competition

In conventional APSC panels during startup wrong contractor gets ON
for a small instance and after that the right contractor gets ON. In many
situations and for many equipment power with reverse phase sequence
for even this small duration is hazardous.

In new Hulasi RYB sequence corrector panels we have used special timers to overcome this problem. In Hulasi APSC panels at all times only the right contractor is ON and hence only the right phase sequence is supplied to the
connected equipment.

This advantage [feature] of Hulasi APSC panels is worth having.
