ABB SPAM150C Motor Protection Relay

Brief Introduction

The SPAM150C Motor Protection Relay is a general purpose combination relay designed primarily for the protection of AC motors for a variety of applications.

It combines a large number of protection functions in one unit. The relay provides a complete set of protection against motor damage caused by various electrical faults.

The relay is also suitable for other equipment requiring thermal overload protection, such as cable or power transformer feeders.

Summary of Protection Functions

The relay thermal overload unit protects the motor against short- and long-term overloads. The maximum permissible continuous load depends on the setting value 1.

Normally this setting value is taken as the rated full load current (FLC) of the motor at an ambient temperature of 40°C. The motor can be overloaded for a short period of time if the motor is not loaded.

When the motor current increases to 1.05I under the above conditions, the thermal overload unit starts after a certain delay.

If the ambient temperature of the motor is below 40°C for a long period of time, the setting value I. can be set to .05…1.10 times the full load current (FLC) of the motor. 1.10 times.

The short-time overload phenomenon mainly occurs during the starting process of the motor. The motor is normally allowed to start twice under cold conditions and once under hot conditions.

One start is permitted under hot conditions, therefore, depending on the starting time of the motor, an integrating value t determining the characteristics of the thermal overload unit can be derived.

This value can be easily determined from the time/current graph in the hot state. t curve is selected from the starting current versus the corresponding starting time (with an appropriate margin).

The t-curve is selected from the starting current versus the corresponding starting time (with an appropriate margin). Using the same value of t, the total permissible starting time of the motor under cold conditions can be found from the cold curve.

ABB SPAD346C Integrated Differential Relay

Features

Integrated three-phase differential relay, overcurrent relay and earth fault relay

Stabilized three-phase differential relays provide winding short-circuit and turn-to-turn fault protection for two-winding transformers and generator-transformer units, and winding short-circuit protection for generators.

Earth fault protection for transformer windings on the HV and LV side according to the required principle:

Stabilized differential current principle, high impedance principle, calculated or measured residual current principle or neutral current principle

Three-stage overcurrent protection for transformer and generator as well as two-stage backup protection for earth fault protection.

Differential relays with operating characteristics that can be easily adapted to different applications Short operating times, stable operation even in the event of partial saturation of the current transformer.

Prevents unwanted operation in the event of faults and transformer inrush currents outside the protective field.

Blocking based on the ratio of the second harmonic to the fundamental component of the differential current prevents unwanted operation in the event of transformer inrush currents.

Blocking based on the ratio of the fifth harmonic to the fundamental component of the differential current prevents unwanted operation in the event of transformer overexcitation.

– If the ratio of the fifth harmonic to the fundamental component of the differential current increases at high overvoltages, this blocking condition can be eliminated

DeltaV high-capacity power supply kits power system electronics and ffeld. This is all the power you need for your DeltaV system.

Benefits

Easy to use. DeltaV High Capacity Power Supplies provide reliable 12 V and 24 VDC power for DeltaV system power and bus ffeld power needs.

They mount easily on T-shaped DIN rails!

Increased availability. Redundant modules based on active MOSFET technology offer higher efficiency and lower voltage drop than conventional diode modules, resulting in less heat dissipation and higher system reliability.

Flexible and Cost-Effective DeltaV Bulk power supplies are flexible and cost-effective to use because of the ability to utilize external redundant modules, for example, if load sharing is required.

Emerson DeltaV Network Smart Switches

Benefits

Plug-and-play installation. Smart Switches feature a DeltaV-compatible setup that installs into the DeltaV network right out of the box.

They require no user configuration to fully support DeltaV network communications. In addition

The default configuration cannot be changed by the user, so you don’t have to worry about installing an incorrectly configured switch.

Automatic lockout prevents unauthorized network connections – Disabling unused network connections is a “best security practice” that helps you comply with plant security policies.

Disabling unused network connections is a “best security practice” that helps you comply with factory security policies.

Emerson DeltaV™ Redundant Controller

Benefits

Uninterrupted control operation. By installing redundant M-Series, S-Series, and PK controllers, you create a “safety net” that

protects your process from unexpected controller failures. In the event of a hardware failure, a backup controller is always available to keep your control and process up and running.

Online upgrades. Installing a redundant DeltaV controller allows you to upgrade your DeltaV system online.

New software can be installed into the backup controller online without disrupting operations.

Once the upgrade is complete, the backup controller is automatically configured and available, allowing you to switch to the new ffrmware without interrupting your process.

Once the switchover is complete, the original active controller can be upgraded. In addition, MQ controllers can be upgraded online to MX controllers.

SQ controllers can be upgraded online to SX controllers. This ensures that your system is always ready to expand as your control strategy evolves.

Automatic commissioning. The system automatically detects, commissions, and downloads spare controllers so you can safely replace equipment.

Add redundancy online by simply installing a new 2-wide backplane with system power and MQ, MX, SQ or SX controllers.

The SZ Controller Carrier or Dual Universal Safety Carrier provides 2 slots for SZ controllers, so there is no need to add anything other than additional SZ controllers.

PK controller carriers also provide 2 slots, so simply add a PK controller to an existing carrier.

The engineering database is automatically updated and the spare controller can be activated by simply assigning and downloading a controller redundancy license, all without interrupting the process.

There are no dip switches, jumpers or addresses to assign. The backup controller automatically assigns the proper backup address and starts working, protecting your process.

Bufferless Transitions The DeltaV controller is designed for bufferless control transitions from the active controller to the standby controller.

During this time, the output channels maintain their output state until the switchover is complete and the control module begins execution.

The control module uses signal status to ensure that all I/O channels are normal before taking control action on them.

All output signals are synchronized via the I/O readback function to ensure that control calculations are made based on the current output state.

When using CHARM or DeltaV Classic I/O cards with or without Foundation™ ffeldbus devices.

This ensures an uninterrupted transfer of control during switchover.
