Application comparison
Oil type versus dry type transformers
Oil type transformers suit outdoor and high-capacity distribution, while dry type transformers are preferred for indoor, fire-sensitive and low-maintenance locations.
Transformer, MV and LV integration
Compact substation planning
A CSS combines transformer, MV switchgear and LT distribution inside a factory-built enclosure, reducing site coordination and installation time.
Transformer standards
Understanding IS 1180 and IEC 60076
These standards guide distribution transformer design, performance, testing and compliance expectations for project approvals.
Switching and distribution
HT and LT panel selection
Select panels based on voltage, current rating, fault level, IP rating, switchgear make, metering, protection and project wiring requirements.
Quality documentation
Pre-dispatch inspection checklist
Review approved drawings, routine test reports, nameplate details, accessories, painting, packing and dispatch readiness before equipment leaves the factory.
