Overview

What this internship makes you able to do.

Every EEE and EE student in India studies Power Systems, Electrical Machines, Power Electronics and Switchgear & Protection. Almost none of them can size a UPS for a GPU hall, read a datacenter single-line diagram, or explain why an operator chooses 2N over N+1 for its UPS but N+1 for its chillers. Meanwhile the industry problem has inverted: a single AI rack now draws 80–130 kW — more than a small office building — and India has over 3 GW of datacenter capacity under construction. The scarcest people on those projects are not software engineers; they are electrical engineers who understand critical power. That is the gap this internship closes.

You work the full power chain the way a datacenter electrical designer does: from the 33/11 kV utility intake through transformers and MV/LV switchgear, into double-conversion UPS systems and their battery autonomy, standby diesel generators and automatic transfer schemes, down to busway and rack PDUs feeding the IT load. You design redundancy topologies (N, N+1, 2N, 2N+1) against Uptime Institute Tier and TIA-942 expectations, engineer earthing and lightning protection to IS 3043 and IEC 62305, run protection-coordination and power-quality studies in ETAP-class tools, compute and improve PUE from real metering data with Python, and size a battery-energy-storage (BESS) plus rooftop-solar layer — the green-power question every Indian datacenter RFP now asks.

The internship is built for the Indian academic calendar and the AICTE/NEP internship mandate. Take it as a 4-week winter sprint, an 8-week summer internship, or a 6-month final-semester capstone that maps to your project/internship credits. Every track ends the same way: a graded, defended capstone — a complete single-line diagram with a redundancy and BESS/solar plan for an AI datacenter hall — a portfolio of calculations and drawings a hiring manager can actually read, an RKR completion certificate, and for the strongest interns a bridge into the RKR datacenter certification ladder and the hiring pipeline behind it.

Built on your syllabus

The courses this internship extends.

You've already studied these. Here's how each one becomes a deployable skill.

Power Systems / Power System AnalysisEEE · EE
AICTE model PS / Anna Univ EE3501 / VTU 21EE71 / JNTU PSA

Load flow, fault levels and per-unit analysis on paper become a real design task: sizing the 33 kV intake, transformers and fault-current ratings for a 5 MW AI hall.

Electrical MachinesEEE · EE
AICTE model EM-I/II / Anna Univ EE3405 / VTU 21EE44

Transformer and alternator theory becomes selecting and sizing dry-type transformers and standby diesel-generator sets — including derating, step-load acceptance and paralleling.

Power ElectronicsEEE · EE · ECE
AICTE model PE / Anna Univ EE3591 / VTU 21EE53

Rectifiers, inverters and converters from your syllabus are exactly what a double-conversion UPS and a BESS power-conversion system are — here you size them, compare topologies and read their efficiency curves.

Switchgear & ProtectionEEE · EE
Anna Univ EE3601 / VTU Protection & Switchgear / JNTU S&P

Relay characteristics and breaker ratings become a protection-coordination study: grading MV/LV breakers and relays in ETAP so a rack-level fault never takes down the hall.

Control SystemsEEE · EE · ECE
AICTE model CS / Anna Univ IC8451 / VTU 21EE54

Feedback and stability theory maps onto how a UPS holds its output through a transfer, how generators share load when paralleled, and how a BESS controller follows a peak-shaving setpoint.

The curriculum

8 modules. 20 labs. Week by week.

This is the full plan for the 8-week track (the winter and semester formats compress or extend the same arc). Every week ends in a deliverable your mentor reviews.

Week 1

From the grid to the GPU: the AI datacenter power chain

Re-anchor your Power Systems theory on a real facility. Walk the full chain — utility intake to rack PDU — and quantify why AI density breaks legacy designs.

You'll do
  • Trace and annotate a reference 5 MW datacenter single-line diagram end to end
  • Build the load estimate: racks at 17 kW vs 80–130 kW AI racks; diversity, growth and cooling loads
  • Compute fault level and per-unit values at the 33 kV intake for the reference hall
Deliverable: Annotated single-line walkthrough + load-estimate workbook for the reference hall
Week 2

MV/LV distribution & transformer sizing

Design the distribution backbone: transformer selection and sizing, MV/LV switchboard layout, cable and busway sizing with derating done properly.

You'll do
  • Size dry-type transformers for the hall including K-factor derating for harmonic-rich IT load
  • Run a load-flow study in ETAP/OpenDSS and verify voltage drop at the farthest rack PDU
  • Size LV cables and busway per IS 732/IEC 60364 derating tables and document every factor
Deliverable: MV/LV distribution design with load-flow results and a defended cable/busway schedule
Week 3

UPS topologies & battery autonomy

The heart of critical power: double-conversion vs line-interactive vs modular UPS, VRLA vs Li-ion strings, and autonomy sizing against generator start time.

You'll do
  • Compare UPS topologies on efficiency curves at partial load; pick and justify one for the AI hall
  • Size the battery string (VRLA vs Li-ion) for a 10-minute autonomy at full load with end-of-life margin
  • Model a mains-fail-to-UPS transfer in Simulink and verify the output stays within the ITIC/CBEMA curve
Deliverable: UPS + battery sizing report with topology justification and transfer simulation evidence
Week 4

Standby generation & redundancy topologies (N+1 / 2N)

Diesel-generator sizing, ATS schemes, and the redundancy vocabulary of the industry — N, N+1, 2N, 2N+1, distributed-redundant — mapped to Uptime Tier III/IV and TIA-942.

You'll do
  • Size DG sets with step-load acceptance and altitude/temperature derating; design the paralleling scheme
  • Draw A-side/B-side 2N distribution to dual-corded racks and an N+1 alternative; cost both
  • Run a concurrent-maintainability walkthrough: prove any single component can be serviced with zero IT downtime
Deliverable: Redundancy design pack: 2N vs N+1 comparison with cost, availability and Tier mapping
Week 5

Switchgear, protection coordination & arc-flash awareness

Make the design safe and selective: breaker and relay selection, time-current grading so faults isolate locally, and an introduction to arc-flash energy and PPE categories.

You'll do
  • Build a protection-coordination (TCC) study in ETAP for the MV-to-PDU chain and fix two miscoordinations
  • Select breakers and relays (IEC 60947/61439 frames) with fault-rating headroom documented
  • Compute incident energy at the LV switchboard and assign arc-flash labels per IEEE 1584 method
Deliverable: Coordination study with corrected TCC curves + arc-flash label set for the hall
Week 6

Earthing, grounding & lightning protection

The layer everyone skips in college: earth-grid design to IS 3043, clean/IT earthing for sensitive loads, and IEC 62305 lightning risk assessment and air-termination design.

You'll do
  • Design the earth grid for the substation yard: soil resistivity, grid resistance, step & touch potentials
  • Separate and document power, IT and lightning earths with bonding per IS 3043 / IEC 60364-5-54
  • Run an IEC 62305 risk assessment and place air terminations by the rolling-sphere method
Deliverable: Earthing & lightning-protection design file with calculations and layout drawings
Week 7

Power quality, metering, PUE & BESS/solar integration

Operate the facility on data: harmonics from IT loads, metering architecture, computing and improving PUE, then layering BESS peak-shaving and rooftop solar into the design.

You'll do
  • Analyse a Fluke 435-class capture dataset: THD, sags, flicker; specify harmonic filtering
  • Compute monthly PUE from a real metering dataset in Python/pandas and find the two biggest losses
  • Size a BESS (peak-shave + UPS-support) and rooftop solar array in HOMER Pro/PVsyst; state the payback
Deliverable: Energy report: PQ findings, PUE analysis notebook, and a sized BESS + solar proposal
Week 8

Capstone: design, defend, and prove the power spine

Put it all together on a fresh brief — a complete electrical design for an AI hall — then defend every sizing, redundancy and protection decision to a mentor panel, like a real design review.

You'll do
  • Produce the full single-line diagram from 33 kV intake to rack PDU for the capstone brief
  • Finalise the redundancy topology, protection grading, earthing scheme and BESS/solar layer
  • Present and defend the design pack and calculations in a live review with injected what-if failures
Deliverable: Capstone design pack: SLD + calculations + redundancy/BESS plan + recorded defence

The capstone

AI Datacenter Hall: Single-Line Diagram, Redundancy & Green-Power Plan

You are handed a written brief for a 5 MW AI hall — 48 GPU racks at ~100 kW each plus cooling and house loads, a 33 kV utility intake, an availability target of Tier III with a Tier IV option priced, and a mandate to cut grid draw with BESS and solar. You must produce the complete electrical design — intake to rack — and defend it live.
