# Main Electricity Monitoring

> Factory-wide power monitoring, 3-phase sub-station distribution and the demand forecasting.

Industrial manufacturing operations consume vast amounts of electrical power. The **Main Electricity** module gives plant engineers, energy auditors, and factory owners real-time visibility into incoming feeder lines, main distribution panels (MDP), and sub-station transformers.

## High-Voltage Feeder & Substation Monitoring

Connected directly to 3-phase potential transformers and current transformers via the **`ipmr226`** integrated power analyzer node, the electricity engine captures true RMS parameters at sub-second resolution:

> [card] Instantaneous Demand (kW)
>
> Live total real power active across the plant, with peak demand thresholds to prevent utility MDI penalties.

> [card] Power Factor Compliance
>
> Continuous Power Factor ($\cos \theta$) auditing across all three phases ($R, Y, B$) to prevent utility penalty surcharges.

> [card] Cumulative Energy (kWh)
>
> Continuous energy integration, tracked today vs. yesterday and broken down by operational shift.

## Dashboard Widgets Explained

### 1. Today's Statistics & Hourly Performance

![Today's Statistics & Total Consumption Card](https://mintcdn.com/kunji-soft-technologies/TnyhoDiDF9en26mf/images/dashboard-electricity-stats-highlight.png?fit=max\&auto=format\&n=TnyhoDiDF9en26mf\&q=85\&s=6dd49f46a57392a9869bbcbea4c3b5e0)

* **Highest vs. Lowest Performance Hours**: Highlights specific hourly blocks exhibiting abnormal surges or optimal power-to-output ratios (e.g., Lowest 03:00–04:00, Highest 07:00–08:00, Hourly Avg 175.45 kWh).
* **Hourly Trend Comparison**: Overlays yesterday's 24-hour demand curve against today's live curve to detect early energy drift.

### 2. Total Consumption & Efficiency Table

The central analytics card tracks daily baseline metrics:

| Metric | Measurement Scope | Utility Value |
| :- | :- | :- |
| **Total Energy (kWh)** | Cumulative kilowatt-hours consumed since midnight (e.g. 4,210.8 kWh). | Verifies utility meter readings against independent digital records. |
| **Hourly Average** | Rolling mean of kilowatt-hours consumed per operating hour (e.g. 175.45 kWh). | Identifies baseline factory consumption during non-production hours. |
| **Best Hour Window** | Time window demonstrating lowest specific energy consumption per piece. | Sets the efficiency benchmark for machine operators and mold setups. |
| **Worst Hour Window** | Time window with peak electrical spikes or idle motor losses. | Exposes operational waste, such as unoptimized compressor idling. |

### 3. Last Seven Days Radial Polar Chart

On the right side of the screen, a high-density radial heat ring visualizes energy demand across 24 hours of the day over the last seven calendar days:

* **Concentric Day Rings**: Each concentric ring represents a discrete date (e.g., 21 Oct through 27 Oct).
* **Radial Hour Axes**: The 24 spokes (12am, 3am, 6am, 9am, 12pm, 3pm, 6pm, 9pm) highlight cyclical factory consumption.
* **Pattern Recognition**: Instantly exposes shift transition spikes, weekend standby loads, and peak-hour utility consumption patterns (Total: 32,963 kWh).

### 4. Six-Month Longitudinal Trends & Days Breakdown

At the bottom of the screen, long-term historical bars aggregate multi-month consumption:

* **Monthly Aggregations**: Compare total kWh across consecutive months (e.g., May through October) to measure seasonal HVAC and chiller load impacts.
* **Daily Dispersion Breakdown**: Stacked bar segments illustrate weekday versus weekend energy distributions across each month.

## Critical Factory Energy Capabilities

### 1. Maximum Demand Indicator (MDI) Penalty Shaving

Most industrial utility tariffs charge heavy penal rates if a factory's instantaneous demand exceeds its sanctioned MDI quota. Industrial PMR computes a rolling 15-minute average demand:

* When load reaches 85% of sanctioned MDI, an amber warning triggers on all supervisor dashboards.
* At 92%, automated audio/SMS notifications advise shifting non-critical batch loads (e.g., raw material granulators or auxiliary water pumps).

### 2. Specific Energy Consumption (SEC)

Energy efficiency is meaningful only when correlated with physical production output:

$\text{SEC} = \frac{\text{Total Substation Energy (kWh)}}{\text{Total Good Pieces Produced (Units)}} = \frac{\text{kWh}}{\text{Piece}}$

Industrial PMR dynamically divides main meter energy by factory piece output, enabling plant owners to evaluate the true electricity cost embedded in each manufactured part.

### 3. 3-Phase Voltage Balance & Power Quality

Unbalanced 3-phase voltages cause excessive heat buildup and premature failure in induction motors. Industrial PMR monitors Phase $R, Y, B$ voltages:

* Phase deviation $> 3\%$ triggers an automatic power quality warning.
* Low power factor ($PF < 0.90$) alerts maintenance teams to inspect capacitor banks and power factor correction (PFC) relays.
