We are offering automatic voltage regulating relay with tpi. Mc's automatic voltage regulating relay with digital tap position indicator, type : hx-4000. description :nmcs microcontroller based automatic voltage regulating relays (avr relays) are latest technology based relays used for regulating the secondary voltage of power transformers with on load tap changer (oltc). The parameter settings are made through the front panel keys & are stored in nvram. Independent time delays can be set for first control pulse & subsequent pulses. Built-in tap displays tap number of power transformer. Oltc is blocked for uv, ov, oc, cf, minmax tap positions & tap fail . In manual mode, tap raiselower can be achieved through front keys. In test mode, relays, display and led indications can be checked. A pair of contacts are available for raise, lower, uv, ov, manual mode, cf, tf & oc. There are two nos. Of 5 amps c.t.s available, one for the over current blocking and l.d.c. & other for measuring the current. Features :microcontroller based architecture with ad converter. password protected. auxiliary supply : 85v-265v acdclinear or inverse time response. relay on timerbuilt-in tap position indicator upto 40 taps. readout of primary secondary voltages, current & tap no. readout of kv ki voltage & current. 7 segment bright red led displays. independent lower, raise & nominal value settings. blocking for uv, ov, oc, control fail, tap fail & minmax tap no. auto manual mode of operation. test mode & factory reset mode. single pulse or continuous pulse operation. line drop compensator (l.d.c.). data logging. modbus rs 485rtc4-20ma output from pt voltage & tpi for scada. pt display of 433v instead of 110v. over current blocking. additional c.t. For measuring the currentblocking for min. & max. Tap no. master slave features.

THESENMCMAKEAUTO RECLOSING RELAYSARE SPECIALLY DESINGED FOR VARIOUS CONTROL PANELS AND MOTOR CONTROL PANELS.OUR RELAYS ARE VERY COST EFFICIENT AND EASY TO OPERATER.IT COMES IN A STANDARD SIZE OF : 96 mm * 96 mm * 65mm.

THIS AUTO RECOLSING RELAY IS OF TWO TYPES:
1) AUTO RECLOSING RELAY - TYPE S.S.
Auto Reclosing Relay with adjustable time delay between 4 to 10 seconds.
THIS S.S. TYPE RELAY CONSISTS OF JUST A SINGLE SHOT .THERE IS A TRIGGER WHICH WHEN IS SWITCHED ON, THE TIMER GETSON AND WITHIN 4 SECONDS TO 10 SECONDS THERELAY IS TRIPPED AND THETIMER IS SWITCHED OFF ACCORDINGLY TO THE VOLTAGE WITHIN THE CIRCUIT.

2) AUTO RECLOSING RELAY - TYPE D.S.Auto Reclosing relay with adjustable time delay between10 sec to 60 sec. for 1st shot and 30 to 180 sec. for 2nd shot.

Introduced in 2000. the instruments are used for variety of control, alarm and tripping applications.
The instruments serve to replce other more expensive equipments.
These meters are exclusively developed at NMC for utter reliability under Industrial Conditions.
The KW (&MW) and Kvar (&Mvar) meters employ a true 4-quadrant multiplier exclusively developed at NMC for accurate true RMS measrement.
This instruments are fully solid state, field proven reliability, microcontrol design, low power consumption and avalable for LT & HT application.

Features:

Available for current AC & DC, Voltage AC & DC, Frequency Process signals 4 20 mA & 0-5 V DC, KW (MW) for single, double & triple element single and three phase and Kvar (Mvar) for double element three phase.

MRD-A : Used for over current under current protection.

MRD-V : Used for over Voltage, under Voltage protection.

MRD-F : Used for over Frequency under Frequency.

MRD-PV:Used for over Process applicationin conjunction with process transducers.

MRD-W: Used for Over load underload alarm & trip.

MRD-W: Used for Demand Monitoring- alarm and trip.

MRD-W: Used for economical running of star-delta amotors.

MRD-var:Used for Single Step Kvar control for HT or LT application.

MRD-W+ MRD-var: Used for Import / Export of power.
