TSSPDCL Sub-Engineer study guide
TSSPDCL Sub-Engineer · Work through your exam, one topic at a time.
The TSSPDCL Sub-Engineer recruitment test is the screening examination used by the Telangana State Southern Power Distribution Company Limited to shortlist candidates for the Sub-Engineer (Electrical) post in its distribution circles. It is aimed at diploma and degree holders in electrical engineering who want a state utility career in operation and maintenance of 11 kV and 33 kV distribution networks, substations, metering and consumer service. The TSSPDCL Sub-Engineer study guide has 12 sections and about 2,740 words.
01Electrical Circuits and Network Theory
Electrical Circuits and Network Theory is the foundation domain: the exam tests steady-state DC and AC circuit analysis, network theorems, resonance, transients, and power concepts. KCL: the algebraic sum of currents at a node is zero; KVL: the algebraic sum of voltages around a loop is zero.
252 words, about 1 min02Electrical Machines (Transformers, DC and AC Machines)
Electrical Machines covers transformers, DC machines, three-phase induction motors, and synchronous machines. The exam tests equivalent circuits, losses, efficiency, speed control, starting, and slip calculations.
231 words, about 1 min03Power Systems (Generation, Transmission, Distribution and Protection)
Power Systems spans generation, transmission, distribution, and protection. The exam tests per-unit quantities, line parameters, sag, insulators, load flow, faults, relays, and circuit breakers.
224 words, about 1 min04Power Electronics and Drives
Power Electronics and Drives tests switching devices, rectifiers, choppers, inverters, AC voltage controllers, and motor drives. SCR is a latching thyristor: it conducts when forward-biased and gate-pulsed, and turns off when current falls below holding current.
214 words, about 1 min05Measurements, Instrumentation and Control Systems
Measurements, Instrumentation and Control Systems tests analog and digital instruments, bridges, transducers, error analysis, and feedback control. PMMC responds to average DC and has a uniform scale; moving iron responds to RMS and works on AC/DC; electrodynamometer is used in wattmeters and transfer instruments.
242 words, about 1 min06Utilization of Electrical Energy and Illumination
Utilization of Electrical Energy and Illumination tests electric heating, welding, traction, electrolysis, drives, and lighting design. Heating: resistance ovens use I²R; induction heating uses eddy currents; dielectric heating suits insulators.
228 words, about 1 min07Basic Electronics and Digital Electronics
Basic Electronics and Digital Electronics tests diodes, BJTs, FETs, op-amps, logic gates, Boolean algebra, flip-flops, counters, and data conversion. Diode: forward drop about 0.7 V for silicon; reverse bias blocks until breakdown.
204 words, about 1 min08Electrical Safety
Electrical Safety tests shock hazards, earthing, protective devices, safe work practices, and emergency response. Current through the body, not voltage alone, causes injury; contact resistance and path matter.
242 words, about 1 min09Estimation and Energy Conservation
Estimation and Energy Conservation tests electrical installation estimating, load and cable sizing, cost calculation, energy audits, and conservation measures. Estimate quantities from wiring layout: points, circuits, conduit, cable, switches, distribution board.
232 words, about 1 min10General Awareness
General Awareness tests static and current affairs with emphasis on India and Telangana, polity, geography, economy, science, and power-sector organizations. Constitution: fundamental rights, directive principles, President, Parliament, judiciary, amendments.
237 words, about 1 min11Reasoning and Quantitative Aptitude
Reasoning and Quantitative Aptitude tests logical deduction and numerical problem solving under time pressure. Series: check differences, ratios, squares/cubes, alternating patterns, and digit operations.
199 words, under 1 min12English Language and Computer Awareness
English Language and Computer Awareness tests grammar, vocabulary, comprehension, and basic computer literacy. Grammar: subject-verb agreement, tense consistency, articles, prepositions, and pronoun reference.
