Power & Utilities

Thermal, hydro and renewable generation, transmission and distribution. Vibration and current diagnostics on turbines, generators, pumps and auxiliary-circuit fans; APC on combustion, water-steam loops and the energy balance.

Strongest combination
Vibration + Current + APC

This mix delivers the most on the industry's key process stages. Details in the cards below.

How it works

Monitored machines — interactive

Draft machines, feed pumps, drives — the auxiliary equipment that trips units more often than boilers do. Measurement points are on the models.

By process stage

Where Liman-Tech applies — stage by stage

For each stage: the equipment worth monitoring and what each method delivers. No fluff.

1

Steam generators and boiler plant

Equipment
Boilers, coal mills, ID fans, FD fans, feed pumps, condensate pumps, gas blowers
Vibro Mills (especially vertical-spindle / bowl coal mills), ID fans, fans, pumps, gearboxes
Current Motors on mills, ID fans, fans, pumps
APC Combustion control, fuel–air ratio, draft, superheated-steam temperature, NOx, fuel flow
Effect: Lower specific fuel consumption (−5–15% with combustion optimization), stable steam pressure, lower emissions
2

Turbine sets and generators

Equipment
Steam / gas turbines, generators, oil pumps, cooling systems, exciters
Vibro Journal bearings, thrust units, turbine–generator couplings, oil systems
Current Stator windings, excitation diagnostics, current signatures under load
APC Load distribution between units, frequency regime, reactive power
Effect: Protection for the plant's most expensive machine: bearing and winding faults show up early
3

Hydropower units (HPP)

Equipment
Hydro generators, wicket gates, oil-pressure units, cooling pumps, gates
Vibro Hydro generators, oil pumps, drainage pumps, gate drives
Current Motors on oil pumps, drainage pumps, gate drives
APC Optimizing power distribution across units, start / stop regimes
Effect: Stable unit operation, fewer unplanned stops
4

Grids and substations

Equipment
Transformers, switchgear, transformer oil pumps, cooling systems, breakers
Vibro Oil pumps, transformer cooling fans
Current Load profiles, metering functions, anomaly detection
APC Distribution coordination, power-quality monitoring (SCADA integration)
Effect: Transparency across the grid, early signals on transformer cooling

Passer-V + Passer-T + Larus-100 — the main data stream and edge processing
Level 2

Power-unit transparency

A single dashboard, alarms, trends

Stack
Strix — dashboard, ISO 10816 alarms, trend analysis
Level 3

Combustion and regime optimization

Boiler plant, energy balance

Stack
Strix APC — computed models, soft sensors, predictive loops

Results in numbers

  • −5–15% fuel with combustion optimization on boiler plant
  • −20–50% electricity on auxiliary-circuit drives (ID fans, fans, pumps) when switched to VFD
  • Early detection of bearing and winding faults — 2–6 months before failure

Industry benchmarks; your actual results follow a site assessment at your operation.

Proven cases

  • TGK-1, Kola branch — design for replacing compressor equipment at HPP-18 and HPP-19, 2017–2018.
  • FGC UES (Federal Grid Company) — reconstruction of metering systems (AMR/AMI) at 35–750 kV substations across the Center, Urals and Northwest grid regions, 2017–2022.
How to buy

Three commercial models

From outright purchase to a service model where you pay out of verified savings.

CAPEX — purchase

You own the hardware and software — the full effect is yours. Transparent and familiar; for critical infrastructure it is the only option.

MaaS — subscription

Monitoring-as-a-Service: 36 months, a monthly base fee plus a share of the verified effect. The performance risk is ours — no effect, nothing beyond the base.

ESCO — energy performance contract

Energy-saving measures with no capital outlay on your side: we invest, repayment comes out of verified savings.
