1 Power and productivityfor a better worldTMPower and productivityfor a better worldTMDS1 Diode-based transient-free capacitor switchMedium voltage productsProvided by Northeast Power Systems, Inc. ( NEPSI )2 Compensation ofreactive power isrequired in differentparts of the network toensure stability, increasecapacity and reduce power losses thanks tohigher power factor. Compensation of reactive powerDS1 the future of switchesDS1 is the first synchronousswitch isolated in dry airspecifically devised and designed for capacitor by Northeast Power Systems, Inc. ( NEPSI ) 3 The perfect combination, regulated by the electronic control unit, between the semiconductors and synchronism with the network allows to increase reliability and efficiency and prolongs the life of by Northeast Power Systems, Inc.

2 ( NEPSI )4 A new operational concept Event-less closing DS1 is able to carry out closing operations on capacitor bankswithout any transient of current, voltage , frequency or thepossibility of prestrike. Switch in open position, capacitor bankis disconnected and isolated from thedistribution moving contact connects thesemiconductor which naturally energizesthe capacitor a quarter of a cycle, the movingcontact closes the switch allowingconduction without power by Northeast Power Systems, Inc. ( NEPSI ) 5DS1 is able to carry out opening operations on capacitor bankswithout any overvoltage or the possibility of restrike. Switch in close position, capacitor bankis connected to the distribution moving contact connects thesemiconductor which allows a cycle later, the moving contactdisconnects the semiconductor and thusthe capacitor bank.

( NEPSI )6 Powering your compensated network Efficiency DS1 allows capacitor banksto be operated safely andfrequently even in back-to-back, allowing more precisetracking of the reactive powerto be compensated. This translates into maximization of the network capacity and installation productivity, as well as a reduction in power losses and CO2 breakerIncomer ModulePower ModulesFusesFusesFusesProvided by Northeast Power Systems, Inc.
