Servo Stabiliser

Power Engineers & Consultants is well known rolling contact type automatic voltage controllers, electroplating and chemical process rectifiers and special purpose transformers. The company offers a servo stabiliser to ensure constant voltage to the consumer, as the electricity supply is often erratic, and load pattern irregular. This affects electrical motors (particularly smaller capacity motors up to 7.5 HP). With the installation of the stabiliser and maintaining a steady 390/400 V, the motor will operate smoothly drawing 15-20% lesser current and correspondingly the relay setting can be reduced by 15-20%. In case single phasing occurs, the relay will trip in 40-50 seconds. The motor can withstand the high current for this period and will be safe. Also, the relays, contractors, switchgears, etc., incorporated with the motor will be safe. Servo stabilisers are available in a wide range and various models. The standard three phase models are suitable for balanced and unbalanced supply and loads. Standard models offer the following features: roller type regulator ? power consumption is 0.5 to 1.5% depending upon the model and input voltage variation; suitable for continuous 100% duty cycle; the carbon (graphite) roller roll, while moving on the coil track, so contact point of the roller goes on changing which prolongs the life of the rollers; life at full load is 15-20 years; negligible losses in full buck/boost condition; and five years unconditional guarantee in India. Application: though stabilisers are useful for any kind of applications, these are most suitable for 24 hour continuous process plants where breakdowns due to fluctuation result in heavy financial losses.
