ABB SPAD 330 C Differential Protection Relay

ABB SPAD 330 C Differential Protection Relay Supplier and Exporter in India

ABB SPAD 330 C Replacement and Availability

ARP IMPEX supplies and exports ABB SPAD 330 C differential protection relays for replacement, maintenance and existing transformer protection panels.

SPAD 330 C is a legacy ABB SPACOM relay mainly used for transformer differential protection. ABB has classified this model as no longer active, so most current requirements are for:

• Replacement of a failed SPAD 330 C
• Matching spare for an existing transformer panel
• Plant shutdown spare
• Maintenance stock
• Discontinued ABB relay requirement
• Modernisation of an older transformer protection system

If you are looking for an ABB SPAD 330 C replacement relay, SPAD 330 C price, old ABB SPACOM relay availability or a transformer differential relay supplier in India, send us the complete relay part code or a clear photograph of the nameplate.

For international enquiries, please mention the quantity and destination country so we can check availability and prepare the quotation accordingly.

Description

ABB SPAD 330 C is a three-phase differential protection relay used mainly for two-winding power transformers and generator-transformer units.

The relay was widely used in older transformer protection panels where fast detection of internal transformer faults was required.

Its main purpose is to protect the transformer against faults within the protected zone, including winding faults and internal short circuits.

SPAD 330 C is still found in older substations, power plants and industrial installations. Because the relay has been discontinued, buyers normally approach us when they need an exact replacement or when an existing transformer protection panel is being upgraded.

ARP IMPEX handles enquiries for ABB SPAD 330 C discontinued relays, matching transformer protection spares and modern ABB transformer protection alternatives.

ABB SPAD 330 C Product Status

• Brand: ABB
• Series: SPACOM / SPAD
• Model: SPAD 330 C
• Product type: Differential protection relay
• Application: Transformer differential protection
• Product status: Legacy / discontinued
• Main equipment: Power transformers and generator-transformer units

SPAD 330 C is a specific ABB relay model rather than a large relay family.

When buying a replacement, we recommend checking the complete order code because different installed relays may have different supply and input arrangements.

Technical Specifications

• Relay type: Three-phase differential protection relay
• Main protection: Transformer differential protection
• Protection function: 87T
• Main application: Two-winding power transformers
• Generator-transformer application: Yes
• Differential protection: Three-phase
• High-set differential stage: Available
• Transformer inrush restraint: Available
• Vector-group compensation: Available
• HV and LV CT ratio correction: Available
• Measured and setting values: Front-panel indication
• Internal self-supervision: Available
• Series: ABB SPACOM

For an exact replacement, details such as CT input, auxiliary supply and relay order code should be checked from the existing unit.

Features

• Three-phase transformer differential protection
• Fast operation for internal transformer faults
• Protection against transformer winding faults
• Protection against internal short circuits
• High-set differential protection stage
• Transformer energisation inrush restraint
• Transformer vector-group compensation
• HV-side CT ratio correction
• LV-side CT ratio correction
• Local indication of measured values and settings
• Internal relay self-supervision
• Suitable for existing transformer protection panels

These are the main features relevant to buyers. For replacement enquiries, the important point is normally whether the new relay can match the existing SPAD 330 C installation.

Applications

ABB SPAD 330 C is mainly used for:

• Power transformer protection
• Two-winding transformer differential protection
• Generator-transformer protection
• Unit transformer protection
• Step-up transformer protection
• Substation transformer protection
• Power plant transformer panels
• Industrial transformer protection
• Existing ABB SPACOM panels
• Legacy transformer protection systems
• Plant shutdown spares
• Transformer protection relay replacement

SPAD 330 C may still be installed in older:

• Power plants
• Utility substations
• Steel plants
• Cement plants
• Refineries
• Petrochemical plants
• Mining operations
• Process industries
• Large industrial facilities

ABB SPAD 330 C Replacement Relay

Since SPAD 330 C is a discontinued ABB relay, replacement enquiries are now more common than new-project requirements.

Buyers normally contact us when:

• An installed SPAD 330 C has failed
• A spare relay is required before plant shutdown
• Existing stock is no longer available
• The same relay is required for an old panel
• The transformer protection panel is being upgraded

For an exact ABB SPAD 330 C replacement, please send:

• Full ABB part/order code
• Nameplate photograph
• Quantity
• Destination country

If the exact legacy relay is not available, a modern ABB transformer protection relay can be considered after reviewing the existing application.

Modern ABB Alternative for SPAD 330 C

For modernisation projects, ABB’s current transformer protection range includes relays such as RET615 and RET620.

These newer relays provide transformer differential protection together with additional protection, monitoring and communication functions.

However, RET615 or RET620 should not be treated as simple plug-in SPAD 330 C replacements.

Before moving from SPAD 330 C to a newer transformer protection relay, the following should be checked:

• Transformer rating
• HV and LV voltage
• Vector group
• HV CT ratio
• LV CT ratio
• Existing trip circuits
• Auxiliary supply
• Existing protection settings
• Panel wiring

For a buyer, you do not need to send all these details in the first email. Start with the SPAD 330 C nameplate, quantity and destination country. Additional technical information can be requested if a modern replacement needs to be selected.
