Maharashtra SSC Power Consumer Energy Meter Pre-Voc/NSQF study plan

Define voltage, current, resistance, power and energy in your own words and write one-line formulas for each with correct SI units.

Solve at least 15 numerical problems using Ohm's law, series and parallel resistance, and single-phase power (P = VI cos φ) with a calculator, showing every step.

Distinguish AC and DC, state the standard Indian supply values (230 V single-phase, 50 Hz) and explain why power factor changes the current drawn for the same load.

List the shock-protection rules for single-phase work: isolation, proving dead, earthing, and use of PPE, and match each rule to a typical metering task.

Explain the difference between active power (kWh), reactive power (kvarh) and apparent power (kVAh), and state which quantity each meter register records.

Draw and label the chain from LT service cable to consumer meter to consumer installation, naming each item and its purpose.

Describe what a CT-operated connection is, why large consumers use CTs and PTs, and why the multiplying factor must be applied to the meter reading.

Identify the statutory and commercial reasons for accurate metering: tariff application, theft detection, and consumer dispute resolution.

Compare induction (electromechanical) and static (electronic) meters on construction, moving parts, accuracy class, tamper features and typical application.

Name and state the function of each major meter component: voltage and current coils or sensors, disc or shunt, register or display, braking magnet, and terminal block.

Explain how a single-phase and a three-phase meter differ in coil or sensor arrangement and in the number of elements used.

Interpret the nameplate data of a meter: voltage, current rating, frequency, accuracy class, constant (rev/kWh or pulses/kWh) and year of manufacture.

Sequence the safe installation steps for a single-phase direct-connected meter, from consumer application and load survey to sealing and commissioning.

Wire a single-phase meter to a load board in a practice setup (or on paper with terminal numbers) and verify incoming and outgoing polarity before energising.

Explain CT-operated three-phase metering connections, including correct polarity (P1/P2, S1/S2), burden, and why secondary terminals must never be left open.

State the conductor size, earthing and sealing requirements that an inspecting officer would check on a new connection.

Read a meter register correctly, compute consumption between two readings, and apply the multiplying factor for CT-operated meters.

Describe the standard accuracy test procedure: test bench setup, load points, permissible error limits and recording of results.

Explain how to check meter constant by counting disc revolutions or pulses against a known load over a measured time, and compute the percentage error.

Diagnose common reading anomalies such as reverse running, creeping, fast or slow registration, and link each to a probable cause.

Build a fault-finding flow for a dead meter, a meter that does not register, a burnt terminal and a display fault, listing the first three checks for each.

Explain the safe procedure to isolate, replace and re-seal a defective meter, including recording the final reading and the meter serial numbers.

Distinguish tamper conditions (magnetic influence, cover opening, reverse current) from genuine component failure and state how each is evidenced.

Describe preventive maintenance actions: terminal tightening, cleaning, seal inspection and periodic testing intervals.

Explain the tariff structure for LT consumers: fixed or demand charges, energy charges in slabs, power factor penalty or incentive, and electricity duty.

Compute a sample monthly bill from given readings, tariff slabs and power factor, showing each line item.

Summarise consumer rights and obligations: meter testing on request, dispute procedure, and the consequences of meter tampering or direct theft.

State the role of the State Electricity Regulatory Commission in approving tariffs and standards of performance.

List the PPE and safe-work practices for metering jobs: insulated tools, rubber gloves, discharge and earthing of circuits, and safe ladder or height work.

Practise the isolation and permit-to-work sequence and describe first aid for electric shock and burns, including CPR steps.

Demonstrate employability basics: a two-minute self-introduction, a clean one-page CV, and correct use of measuring instruments such as multimeter and clamp meter.

Revise all domains using a timed 60-question mock test and review every wrong answer to its source concept.
