Description:
The PropSava 3 Phase (360V to 450V) SCR System is an automated hybrid voltage regulator and stabiliser; which uses solid state switching, transformers, sensors and control systems; managed by a state-of-the-art digital computer system. The PropSava is connected after the electric meter and site Master Breaker Switch and before the Distribution/Fuse Box. All power to the site/building passes through the PropSava.

Purpose and Use:
The purpose of the PropSava is to automatically control incoming mains over or under-voltage to any site or building; and maintain the design output voltage settings.

Benefits:
Where sites/buildings experience main voltage delivery over 220V, the electrical equipment is over-powered. Power is wasted and equipment suffers premature failure and reduced life expectancy.“A 230V linear appliance used on a 240V supply will take 4.3% more current and will consume almost 9% more energy.” (Electricians Guide16th Edition BS7671)

Why Does Over-Voltage Occur?
Over and under voltage is generally a chronic problem aggravated by a number of factors beyond the end user's control. Electric utilities try to maintain voltage levels delivered to customers at ±5% the agreed output. However, factors like weather, high demand and others can cause the utility voltage to fall within a ±10% range. Even under ideal conditions, most customers will see a drop in utility voltage levels over the course of the day as demand begins to increase around 8 AM and peaks around 3 or 4 PM. Distribution system characteristics can also contribute to chronically low voltage situations. For example, customers at the end of a long distribution line may be subject to a permanent voltage drop due to line losses on top of the utility voltage variations.

Technology - Control and Management Systems:
The PropSava is a pure linear Contactless system based upon electromagnetic induction principles. This system is used in our single and three phase systems. The Contactless system is managed and controlled by our newly developed computer chip and software system. The computer chip controlled system and software is the key to the consistent efficiency of our Contactless voltage regulator; making some 8 million calculations per second. This extremely fast measuring of all data allows the PropSava to rapidly identify, measure, and implement the necessary control changes to ensure that the outgoing voltage is maintained at the pre-set limits within 0.042 seconds - 42 milliseconds.

SCR:
To ensure that the PropSava voltage control system keeps up with the speed of the onboard computer chip system and software, we have used the latest German manufactured silicon controlled rectifiers (SCR). SCR's have no wear out mechanism related to number of switching operations so much higher switching rates can be used bringing higher speed, smoother power delivery and flexibility.

Our ongoing development with the manufacturers of these advanced SCR’s has not only increased the speed and reliability but has also eliminated the wave distortion characteristics of other manufacturer’s types to less than 0.1%.

• Surge Protection eliminates damage to system and site equipment;
• Software system logs all power quality readings which can be used to predict equipment failure.

System Compatibility:
The PropSava will work with on any 3 Phase mains supply with incoming voltage between 360V to 450V and can control and regulate the output voltage to 380V±1.5%.

Software Power Quality Management System (PQMS) - Optional:
This optional system is available on all VPHK products. PQMS consists of a smart metering system with management software. PQMS software is a Windows-based application primarily used to configure and retrieve data from the metering system. This software allows Users to see current and past power quality readings with customisable displays, presented as tables or as graphs.

PQMS provides multi-users with three (3) access levels. Wizards enable easy set up of common operational functions like adding and changing sites/VPHK Systems, reading files, task files, schedules and system information. PQMS displays instantaneous power quality readings which are stored in the database for analysis at any time.

Features of Power Quality Management System - Optional:
• Configuration of a single of multiple VPHK Systems.
• Real time display of voltage, current, Kilowatts, power factor, waveform, harmonics, alarms etc.
• User access levels: Read Only Access (RO), Read & Write Access & Read, Write & Modify.
• Data retrieval (event logs, alarm logs, sag/swell logs, tamper logs) to generate reports.
• Schedule downloads of historical data on a daily, weekly, fortnightly, and monthly basis.
• Data export to OLEDB/ODBC databases for storage and management.
• Customisable features and menus.
• Device/meter communication options such as TCP/IP, UDP/IP, RS485/232, PLC, GSM/GPRS.
