Operator guide

Who this guide is for

This guide is written for 33 KV substation operators, line staff, and shift in-charges who enter daily operational evidence in QT33. Language is kept simple on purpose—Marathi or Hindi terms used in the yard can be spoken in handover even when the app labels are in English. If you are a new operator, read this once with your senior, then keep the Daily Log screen open during the shift.

What to enter every day (minimum checklist)

• Confirm operational date and substation on every module before typing.
• DLR hourly readings for the full shift span your office requires.
• Feeder-wise kWh or ampere entries where the chart asks for them.
• All interruptions with correct from/to time and type (LS/BD/EF/OC as applicable).
• Battery log if your checklist says daily (voltage, charger, remarks).
• Any fault, trip, or emergency event on the fault register the same day.
• Maintenance work started or completed on the maintenance register.
• Charge handover note at shift end with pending items clearly written.

DLR hourly readings — practical tips

Read meters at the same clock intervals each day (for example on the hour). If a reading is taken late, note the actual time in remarks only if your circle allows—otherwise align to the standard hour slot. Double-check decimal points on kWh meters; a misplaced decimal will distort monthly consumption.

When a feeder is off load, enter zero or off-state values as trained—do not copy yesterday’s reading. For parallel transformers, follow your substation SOP on which meter represents the DLR chart row.

Feeder kWh and ampere entries

Feeder columns must match masters. If you do not see a feeder, stop and ask the admin to add it—do not use “other” remarks as a substitute. Ampere readings on heavily loaded feeders should be compared with rated capacity; unusually high amps without a matching interruption may indicate a recording error.

Interruptions: LS, BD, EF, OC

Load shedding (LS) is planned roster interruption. Breakdown (BD) is equipment or line fault. Emergency fault (EF) and over-current (OC) trips should match SCADA or relay indications when available. Always enter from-time first, then to-time after restoration. If restoration time is unknown at handover, enter partial data with a clear remark and complete after restoration.

Shift handover records

Outgoing operator writes pending faults, live permits, telecom issues, and abnormal battery readings. Incoming operator reads the note, acknowledges, and only then starts fresh DLR entries for the new shift. Disputes decrease when both names appear on the handover screen.

Common mistakes and validation

Use saved-record list screens to verify entries before month-end. View opens read-only detail; edit only if your role allows and policy permits corrections.

• Wrong operational date (yesterday selected) — check date bar first.
• Interruption to-time before from-time — fix before save.
• Feeder selected from another substation — refresh masters assignment.
• Duplicate interruption for the same event — search saved records.
• Missing hours in DLR chart — monthly completeness report will flag gaps.
• Printing reports before correcting the same day’s entries.

Monthly report preparation

On the last day of the month, reconcile DLR, interruptions, and faults with the shift diary. Run Report Center for the closed month only after all operational dates are complete. Compare QT33 totals with manual summations for at least one feeder and one interruption type before signing the printout.

Attach printouts per office habit; QT33 PDF is a convenience copy, not a replacement for official books unless your department approves it.

Backup safety tips (especially offline app)

For connected accounts, contact your admin or email [email protected] if sync fails—do not reinstall blindly.

• Export backup weekly and after large data entry days.
• Keep two copies: phone storage and email/cloud per IT rules.
• Before uninstalling, export backup and verify file opens.
• Do not share backup files publicly—they contain operational data.
• Label files with substation name and date range.
