Product Profile of Three Phase Sensing Automatic Power Factor Correction Relays
Trinity Energy Systems [P] Ltd manufactures Three Phase Sensing Automatic Power Factor Correction Relays. Trinity Energy Systems [P] Ltd is ISO 9001:2000 certified that offers electronic power and energy meters and power factor controllers. The Three Phase Sensing Automatic Power Factor Correction Relays consists of four products, with ACCUVAR as the base model, and other three models with a host of value enhancing features. All the models are Microcontroller based, with designs that have been field proven for more then fourteen years. The main features of the VAR controllers are:
Key Features of Three Phase Sensing Automatic Power Factor Correction Relays
- Ease of installation: All models have an auto sense feature, which senses the sizes of the capacitor banks connected on each stage automatically. No need to programme C/K or bank sizes manually.
- Low current operation: Since there is no fixed sequence of switching capacitors, if very small capacitor banks are connected, these controllers sense down to 1% of the main load and take corrective action.
- Data Logging: which is a 12 stage controller, also has on-board RTC and 2Mbytes of non-volatile memory. Thus, it can log all relevant data like electrical system snap-shot, banks in operation at that time, event data like over voltages, trips etc. This data can then be downloaded using the USB port on the back of the unit.
- Intelligent Control: The control parameter is VAR, and not PF. Target PF value is just used to calculate the capacitive VAR required to be added/removed to achieve the desired PF. e.g. If the target PF is unity, means that the target VAR in the system is zero. If system KVAR is 200 lagging, then the controller needs to add 200 KVAR of capacitor banks to reach zero VAR.
