LT Eletrical Panels

Electrical Panel is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit, in a common enclosure. JD Group manufactures Electrical panels a per specifications.

 

Following are few types of LT Panels manufactured by us

 

HT Electrical Panels

JD Group is the Core Component Partner of Schneider Electric for HT range. The international standards of full range is available at JD Group works. JD Group is manufacturing cubicles and is integrating the MV COMPONENTS into MV Switchboard. The final Medium Voltage Switchboard is designed, manufactured and tested by JD Group with the help of Schneider Electric MV COMPONENTS.

  8. PIX basic kit / Power Module and relays like Sepam, MICOM, Vamp etc.
Servo Voltage Stabilizers

The Servo Voltage Stabilizer functions to stabilize voltage and counter voltage functions.

 

Why Servo Voltage Stabilizer is required?

  1. Fluctuation of main supply voltage
  2. Motors draw high current at high or low voltage and this causes burn-outs
  3. At higher voltage power consumption and failure of illumination system increases.
  4. At low voltage illumination suffers
  5. Problem of unbalanced three phase supply
  6. The voltage of three phases in the supply line may not be the same due to uneven load of each phase.
  7. Substantial reduction of performance of the motor and electrical system
  8. Heavy load on motor may result in its burn-out and excessive draw-out of current.

Auto Changeover and Current Limiter

ACCL is a Fully Automatic High Precision System for Efficient Distribution of Individually Controlled Generator Power in High Rise Apartments, Group Housing Complexes, Townships & Residential & Commercial Buildings throughout India.

 

Features

  1. Total automation at no extra cost & outdated manual system
  2. No restriction on choice of generator power points, no separate wiring required.
  3. Assured available of allotted current
  4. Space saving & wiring.
  5. Fail safe, tamper proof and maintenance free.
  6. Simplifies electrical complexity.
  7. Safeguards generator by gradual loading & precision monitoring.
  8. Fully solid state, using imported precision components.
  9. LED indications of all operating stage.
  10. Wide range of 3 phase & 1 phase models.
  11. Tested at National Test House (NTH)

 

Function

  1. The ACCL allow unrestricted supply from mains.
  2. When the main supply fails & standby Generator supply is on. It connects the DG power to each consumer in sequence & starts monitoring its load.
  3. The generator current allotment is software calibrated in Amps & sealed in each ACCL as per buyer’s specification & is available on all load circuits.
  4. Whenever the load current exceeds the allotment, power is automatically switched off for 8/10/12 seconds, and then automatically restored when load is minimized

 

Single Phase ACCL

  4. 2 – 10 seconds delayed mains transfer for added safety
  5. Gives PRE-TRIP LED Indication

 

Three Phase ACCL

  1. Automatic source changeover cum self resetting current limiter primarily for single phase loads (lighting & power) distributed over a three phase (TPN) supply network
  2. The entire generator allotment is available on all three load circuits, and may be used for any load on any phase so long the SUMTOTAL drawing is within limit
  3. Main capacity: 100 Amps
