GENERAL FUNCTIONS MODE OPERATION
inductive reactive current required induction motors three-phase magnetic field additional load power supply network, lines switching devices. also increases expenditure energy paid Electrical Power Supply Utility, although so-called reactive energy facto, real energy consumption. This inductive reactive current will compensated means Power Factor Controller with related capacitor units. ESTAmat Controller applied wherever automatic control power factor (cos) required. functions ESTAmat controlled microprocessor. protective device (watchdog) continuously monitors processor guarantee faultless operation. There internal time date functions. measurable variable current voltage conducted across (related fundamental frequency) band-pass filter. Thus harmonics existing network cannot affect measurement process. Both measurement entries potential free. measuring voltage shall range optionally connected between phase neutral phase phase. current measuring range 0.025 there need differentiate between X/1A X/5A current transformer. measuring cycle lasts seconds. During this cycle, values measured, required parameters (such power factor, current, harmonic current) calculated, and, necessary, additional actions such switching steps activating alarms taken. Using respectively relay contacts, currently required capacitor output achieved equal different step sizes obtain optimized switching performance. case actual power factor lower than target power factor, demand reactive current compensation exceeds smallest capacitor step (measuring current 100% between mA), ESTAmat will switch next step. Allowing possibly still valid re-switching blocking delay time, this switching done after either automatic load depending fixed preset switching delay time. When standard switching circular mode setting applied, ESTAmat distributes total number switching operations uniformly connected capacitor steps. Delay times switching steps either left automatic preset fixed value, done re-switching blocking delay time. ESTAmat Controller capable determining, during start-up procedure, location current transformer well output rating connected capacitor steps (i.e. switching program) means test switchings. When controller mounted into switch cabinet, cabinet's internal temperature monitored internal temperature sensor. setting limit values, alarm function activated. setting menu done means three keys front panel, which locked thus protected against unauthorized modification. turning from automatic manual operation, automatic control deactivated during start-up procedure test purposes, allowing capacitors switched manually. Moreover case circular switching mode, number same-sized capacitor steps defined fixed steps. circular step, however, shall remain control operation.

TYPE ESTAmat PFC/MSP MEDIUM VOLTAGE APPLICATIONS
When using medium-voltage version ESTAmat, following differences from low-voltage version should considered: Modes initialization Fully automatic semi-automatic initialization modes feasible. Therefore only manual initialization possible preset. operator will have current transformer location, output number capacitor steps, C/k-value, switching program. Blocking delay time re-switching re-switching blocking delay time seconds seconds (preset value).

During start-up routine, ESTAmat Controller capable independently determining location current transformer well output rating connected capacitor steps means test switchings. Three modes initialization possible: Fully automatic initialization AU1: ESTAmat Controller determines location current transformer, output number capacitor steps, switching program. Semi-automatic initialization AU2: ESTAmat Controller determines, after presetting location current transformer, output number capacitor steps switching program. Manual initialization AU3: location current transformer, output number capacitor steps, switching program have operator. ESTAmat Controller supplied with fully automatic initialization mode default setting. fully automatic initialization successful case strong oscillations public power lines. such case, semi-automatic manual initialization applied.

AUTOMATIC MANUAL OPERATING MODE
automatic operating mode, capacitors automatically switched depending demand reactive power. actual power factor shown display. minus front power factor means that power factor capacitive. testing purposes, capacitors switched manually time automatic operating mode. When manual operating mode set, automatic operating mode deactivated, i.e. capacitor steps switched. manual operating mode called upon from other mode.
SWITCHING CIRCULAR MODE
Switching circular mode means that capacitors which have been switched first, will also switched again first. Switching follows first first (FIFO) principle. switching-in follows order 1-2-3-4-5, then also switching-out capacitors will follow that same order 1-2-3-4-5. circular switching mode distributes load uniformly elements such contactors capacitors. further advantage this mode that capacitor step, when switched out, enough time discharging before switched again. advantages circular switching sequence also applicable "hunting" programs. With switching sequence 1:2:2:2:2:2, example, "double-size" steps likewise switched circular switching sequence. "single-size" step will then used only fine tuning. With switching programs equivalent hunting steps, e.g. 1:1:2:2:4, hunting steps same size (1:1 2:2) will also switched alternately.
NO-VOLTAGE RELAY
case interruption mains voltage, ESTAmat Controller switches capacitor steps. When supply voltage restored, capacitors will switched again after blocking delay re-switching elapsed. This ensures enough time capacitors discharge thus avoids harmful switching-in phase opposition mains voltage.

CONNECTION CURRENT TRANSFORMER
case unbalanced load phases, current transformer should connected phase which most highly loaded. current transformer should installed position which ensures that subsequent consumer current, including capacitor current, will flow through Normally, this position next feed-in transformer load side tariff meter reading. Parallel operation: case network sections, each with independent power factor control equipment, interconnected, power factor controllers influence each other, because currents distribute across transformers. such case, avoid hunting power factor controllers, C/k-values should different current levels with manual initialization mode AU3. result will "lead-follow" behavior because both controllers react different speed. power factor controller with lower value quicker switching than with higher value. Summation current transformer: When several transformers supply single L.V. bar, individual currents should measured means current transformers then added together summation current transformer. Special attention should given correct polarity, since otherwise, current intensities individual transformers will subtract.
OPTIMIZED SWITCHING PERFORMANCE
ESTAmat Controller continuously measures demand reactive power changes this demand, thanks optimized switching performance, switches largest possible capacitor step. case example, power factor correction equipment kvar, ESTAmat Controller will immediately switch step kvar instead gradually switching steps kvar. This way, number switching operations reduced, which results increased life expectancy both capacitors contactors.

TEMPERATURE MONITORING
Using internal temperature sensor located lower part casing, ESTAmat Controller continually measure ambient temperature. Although sensor installed within device, venting slots allow sufficient circulation enable accurate measurements. When controller mounted into switch cabinet, internal temperature also monitored. setting limit values, alarm function activated.
CURRENT HARMONIC CURRENT
root-mean-square ("rms") current Ieff comprises fundamental frequency current plus harmonic components. Using Fast Fourier Transformation (FFT) analysis, ESTAmat Controller determine harmonic currents 3rd, 5th, 7th, 11th, 13th, 17th, 19th harmonic. These displayed percentage value relative current fundamental frequency. controller displays percentage values 17th harmonic. harmonic generators exist resonance frequency between compensation equipment line transformer typical harmonic frequency, percentage part this harmonic increases excessively. This activate alarms switch-out operations means various limit-value profiles.

FUNCTIONING ALARM RELAY
During normal operation, alarm relay operative auxiliary contact open. case faults breakdown supply voltage, this contact closes. fault alarm relay additional means monitoring correct operation. Users select which these fault conditions will activate alarm relay: Undercompensation, i.e. when plant sufficiently compensated more than minutes continuously with power factor below 0.9. condition compensation having become insufficient other faults will perceived time thus eliminated. Measuring current low, secondary current C.T. less than Measuring current high, secondary current C.T. higher than measuring voltage, connection supply have broken Over-temperature, i.e. preset maximum ambient temperature been exceeded.
root-mean-square current high, i.e. relation Ieff/Ifund between root-mean-square value frequency value current exceeded fundamental specified limit. harmonic current high, i.e. specified percentage amount harmonic been exceeded.
Sometimes appropriate switch capacitor steps when certain alarm signals given. user select which fault alarms will cause switch-out. specific kind fault alarm determines switch-out behavior indicates priorities: capacitor steps will switched immediately without time delay. capacitor steps will switched after time delay which modified. Steps will continue being switched until fault alarm disappeared.
