Main switchboards

  • Our main switchboards are adaptable to any combination of generators without any limitation.
  • Arranging generator sets for synchronising, parallel operation for the purpose of continuous load sharing and load transfer using power management system (PMS).
  • The basic function of PMS is to ensure consistency and maximum efficiency of power generation equipment, therefore we do class compliant custom programming on PMS to match customer requirements and application.
  • Providing tie-breaker between MSB and busbars.
  • Providing auto start feature of standby generator to prevent any possibility of a blackout.
  • Preferential trip system to prevent single generator overload.
  • Providing interlock such that connection of shore power to main switchboard bus line does not allow closing of any DG or EDG breaker.
  • Preventing emergency generator from running with any of the main gensets or shore power in parallel operation, continuously.
  • Custom designed enclosures, made of 14SWG sheet steel for maximum rigidity and lifespan.
  • Multi-cubicle, front and/or rear access, self-supporting, and dead-front type designs with ingress protection rating of IP23 to IP44.

Emergency switchboards

  • The emergency switchboard designed by us is made for reliable operation in the event of an emergency, and in such circumstances, it shall automatically activate as the emergency power distribution centre.
  • Emergency switchboard is made similar to the construction and operation with respect to all safety measures of main switchboard.
  • Under normal operating conditions, the emergency switchboard shall be energised from the ship’s main switchboard with the ship’s main or emergency bus-tie circuit breaker and emergency generator circuit breaker remains open.
  • On loss of ship’s service supply, the bus-tie breaker shall be tripped and emergency generator will be automatically started, which in turn allows the emergency circuit breaker automatically be closed to restore power to the emergency services.
  • Mod-bus serial link can be provided from emergency switchboard to ship’s alarm monitoring system to transfer all alarms and indications.
  • Emergency switchboard provided with necessary indications and monitoring equipment as required by Class authority.

Power management system
PMS is an advanced system for full automation of power plant, including power management, diesel engine control, generator control, generator protection, and optional diesel engine safety system. Each generator set is equipped with it’s own independent and autonomous PMS system. This ensures highest degree of reliability and availability. PMS is supplied as a complete product and no additional components are needed for automation of a low voltage switchboard up to 690VAC.

Electrical drive systems
With energy efficiency as the key goal, we design and deliver electrical AC drive systems for maritime applications, which provide great advantages over conventional systems. Electrical drive systems are designed to distribute power to marine, process plants, and offshore applications such as pumps, propulsion systems, heavy duty pumps, HVAC, ventilators and winches, etc. Equipped to handle harmonic distortions, dynamic responses, and regenerative energy. Designs comply with class requirements of ABS, Lloyds, DNV, BV, and GL.

Group starter panels & Motor control circuit panels
Available in free standing or wall mounting designs, with dead front, and drip-proof make. Totally enclosed cubicle type construction and conforming to IP 23 to 56 rating. Providing separate full voltage non-reversal, combination, three-phase or four-phase, magnetic motor starters. Each starter panels are provided with motor power circuit protection and control circuit protection. Providing magnetic motor contactor with replaceable contacts. Provided with all indications and monitoring devices as per class requirements. Interfacing starter controls to external control system (alarm system, level gauging system, etc.) as per customer requirement.

Distribution boards
Providing AC and DC distribution boards from 0 to 440 volts. Enclosures from reputed manufacturers such as Rittal, Schnieder, ABB etc. with ratings of IP44 to IP64. All control functions, indications, meters, switches, etc can be provided as per class and customer requirements. Distribution boards are provided with neoprene anti-hygroscopic rubber all around the door to make panel dust or vermin proof.
