Why Titan PQ
Three reasons commissioning engineers, EHV consultants, and tender writers specify Titan PQ for permanent power-quality monitoring instead of an annual analyser audit.
IEC 61000-4-30 Class S
Power quality measurement to the standard that tender writers cite. 10/12-cycle aggregation, IEEE 1588 time sync, IEC 62586-2 PQI-S third-party validation.
Analyser-Class PQ Features on a DIN Rail
Harmonics to 63rd plus inter-harmonics, flicker per IEC 61000-4-15, transient capture above 50 μs with waveform recording, voltage unbalance with sequence components, RVC, and ITIC/CBEMA curve classification — usually only on portable analysers.
Revenue-Grade Energy Metering
Class 0.2S active energy and Class 0.5S reactive energy per IEC 62053 — so the same device delivers the energy bill audit and the power-quality audit. 4-quadrant kWh/kvarh/kVAh, sliding-window demand, up to 8 TOU/TOD tariffs.
The Problem
Industrial facilities with sensitive loads — drives, VFDs, data-centre IT, semiconductor process equipment, hospital imaging — see voltage events, harmonic distortion, and flicker that an energy meter does not capture. Portable PQ analysers visit for a few weeks, measure deeply, then leave. The events that take a line down often happen between visits.
Permanent DIN rail PQ meters from international vendors deliver most metering basics but stop short of analyser features — flicker, transients, ITIC/CBEMA classification, RVC, gapless measurement. Tender writers asking for IEC 61000-4-30 or PQI-S certification are pushed toward ₹3-5 lakh imported devices.
Titan PQ closes that gap — analyser-class measurement on a compact DIN-rail device.
Voltage Sag, Swell, Transient & THD Harmonics Monitoring
Plant managers, data-centre operations and hospital BMS teams don't hunt for “a power quality meter” — they chase symptoms. A drive that trips at random. UPS that goes to battery for no logged reason. A transformer running hot. A chiller compressor that fails six months early. The forensic evidence sits in the voltage sag and swell events, transients, harmonics and THD that a regular energy meter never captured. Titan PQ is the permanent industrial monitor that catches all of them.
On a single DIN rail device:
- →Voltage sag & swell monitor: IEC 61000-4-30 Class S half-cycle RMS detection across all three phases. Sags below 90 %, swells above 110 %, interruptions below 5 %, with ITIC / CBEMA / SEMI F47 classification per event.
- →Transient capture: voltage transients above 50 µs duration captured with pre-trigger waveform — the events that destroy electronics but never show up in an energy log.
- →Industrial THD harmonics analyzer: full harmonic spectrum to the 63rd order plus inter-harmonics, TDD calculation, and harmonic-direction flagging — so blame for distortion at the point of common coupling can actually be settled.
- →Flicker & RVC: IEC 61000-4-15 Pst / Plt flicker plus Rapid Voltage Change tracking — the metrics tender writers ask for and portable analysers usually leave behind.
- →Gapless measurement: continuous recording 24/7, not the 30-second skip every 10 seconds that affordable PQ meters fall back to.
Sites where this matters: data centres tracking IT-load PQ for uptime SLAs, hospitals protecting imaging equipment, paint shops and semiconductor lines where a 2-cycle sag drops a batch, and any facility filing IEEE 519 or EN 50160 compliance reports against a DISCOM dispute. The full spec set is in the Power Quality Features section below.

Applications
Where permanent power-quality monitoring earns its keep.
Industrial Plants & Process Lines
Sensitive drives, VFDs, induction furnaces, and electronics loads see harmonics, sags, and flicker that an energy meter alone misses. Titan PQ provides the diagnostic trail when a sub-station event takes a line down.
Data Centres
Continuous monitoring of harmonic distortion, voltage events, and power factor for IT-load circuits. Waveform-level evidence for SLA, insurance, and uptime audits.
Solar & Hybrid Plants
Inverter-led harmonic injection, anti-islanding events, and grid-side voltage variations measured against the CEA harmonics regulation. Useful evidence for utility / DISCOM disputes.
Hospitals & Critical Infrastructure
Power-quality assurance for life-safety and imaging loads. Sags, swells, and transients captured with waveform context for root-cause analysis.
