Auto Transformer Starters
Controller panel

⇒ Auto Transformer provides voltage to the motor at start.
⇒ Appropriate lower voltage tapping –customized as per the application – is provided to the motor.
⇒ After the motor has attained significant torque changeover from Auto Transformer to On Line takes place.

Stator Rotor Controller

⇒ Interlocking between stator and rotor as per ISS: 8544 (part III).
⇒ Offers improvements in reliability as compared to L.R.S..
⇒ Low maintence; incorporates switching through contactors.
⇒ Smooth acceleration of the slip-ring induction motor.

Munnalal Motor Protector
(MLMP)

⇒ Provision of tripping automatically the Starter in case of overload, due to which it gives relief from the worry of burning the motor.
⇒ If there is phase short circuit or earthing in starter outgoing, then MCB of starter will trip automatically due to which fault doesn’t multiply.
⇒ Due to presence of rubber gasket starter is completely protected from dust, mud, water.

Munnalal Pump Protector
(MLPP)

⇒ Provision of Starting Starter automatically when all the 3 phases are available, due to which maximum voltage is always available & will give freedom from starting & stopping again-n-again.
⇒ Due to presence of rubber gasket is completely protected from dust, mud & water.
⇒ Incoming & outgoing (3phase, Multi lock type) terminals are provided separately.

Our Products - Power & Distribution Transformers

Motor is connected in Delta from the start.

‹ Production Range

Power & Distribution Transformers 16 KVA to 2000 KVA upto 33 KV.

‹ Standards

Syemco Transformers are designed and tested as per IS:2026, BS-171, IEC-76 & IEC-726.

‹ Vector Group

Transformers will be connected as per vector group reference DYn 11. Other vector groups can be offered as per specific requirements.

‹ Terminal Arrangement

H.V. Bare Bushings or Cable Box, L.V. Bare Bushing or Cable Box Disconnecting.

‹ Temperature Rise

Syemco Transformers are designed for a maximum temperature rise of 40/500 C of oil/ winding. Lower temperature rise can be offered on request.

‹ Core

The core is constructed from low loss, cold rolled, grain oriented, annealed laminations of electrical sheet steel conforming to the latest international standards. Special frame is built in-house form clamping the core to reduce the magnetic noise as well as making the whole structure rigid and robust.

‹ Windings

Coils are wound with electrolytic high conductivity paper covered of synthetic enamelled copper conductors. Cooling ducts are provided to keep the hot spot temperature as low as possible. Coils are dried in electric ovens. Rigid connection support and coil clamping is provided to ensure high short circuit strength.

‹ Insulation

Precompressed board PARMALI board and JAPANEESE insulation paper of best quality is used.

‹ Tappings

A. OFF CIRCUIT TAP CHANGING SWITCH Tappings from + 5% to -5% for HV variation or as per customer's requirement. B. ON LOAD TAP CHANGER 16 steps OLTC for HV variation from +5% to -15% in steps of 1.25% or as per specific requirements. OLTC for remote/ auto/ parallel operation can also be offered.

‹ Oil

Oil is tested for resistivity, dielectric and acidic characteristic conforming to IS-335. Before topping up oil is filtered throughly.

‹ Tanks

The tanks are made of M.S. steel plates/ sheets with adequate bracing & stiffness. Tanks are pressure tested to withstand any type of inside or outside pressure, all the external surface are given a primary coat of zinc chromate, red oxide and two finishing coats of grey paint. The inner surfaces are given a coat of heat and oil resisting paint.

‹ Quality Control and Routine Test

All Syemco transformers undergo rigorous quality control check and are routine tested as per IS in our fully equipped laboratory. Any specific test required by the customer can also be arranged.
