The M-5329 Three-Phase LTC Backup Control provides extra protection

to save your customers from the hazards and inconvenience of excessively

high or low voltage on any phase. Defective LTC tapchanger controls can

cause either too high or too low a voltage along the line.

This can possibly damage customers’ motors, computers, or televisions.

Even when the control is operating properly, customers close to the

transformer may receive dangerously high voltage as the line drop compensator

attempts to maintain a constant voltage under heavy load at a central point on

the distribution line. The Beckwith Electric M-5329 LTC Backup Control can be

installed as a solution to both of these problems. It will prevent a defective LTC

tapchanger control from running the voltage outside the upper and lower voltage

limits and will prevent the line drop compensator from raising the voltage too

high under full load or overload conditions.

• Set the voltage bands on the M-5329 slightly wider than the transformer control

limits to ensure that a failed control will not result in a runaway LTC transformer.

• Under full or overload conditions, the M-5329 automatically takes over as an upper

voltage limit control that is not affected by load current, to prevent damage to

equipment close to the transformer.

• While the Block Raise contact prevents a raise operation, a Lower contact forces

the tapchanger down if the primary voltage subsequently rises.Capabilities of the

M-5329 include:

• Provides all components that must be added to an LTC Transformer for paralleling,

using the circulating current method.

• Prevents a defective LTC tapchanger control from running the voltage outside the

upper or lower limits.

• Prevents the line drop compensator from raising the voltage too high under full or

overload conditions.

• Monitors all three-phases and blocks LTC tapchanger operation if any phase is

outside the setpoints.Additionally, the M-5329 is fully transient protected and operates

within ±1% voltage accuracy over a temperature range of -40° to +80° C.

The M-0127A AC Current Relay guards against excessive circulating current using the circulationg current

method or the ∆VAR® 1 method. The M-0127A can be used in other current- and voltage-sensing

applications. Its adjustment range is 0.01 to 0.1 A.

Additional Applications

The M‑0127A and M‑0170A can be used wherever an adjustable, low burden AC relay is required. They

have virtually no time delay, a very small hysteresis and a normally closed output for use on AC only. The

relay output draws approximately 6 mA of in‑phase current through a 120 Vac load when open. These factors

must be considered for the user’s specific application.

By adding external series resistors, the relays may be used for voltage sensing. For example, with a 10 K

series resistor, the M‑0127A is adjustable from 100 to 140 Vac, using 10 to 14 mA current setting range.

Use of a 10 K, 10 W wire‑wound resistor is suggested.

M‑0127A Application

The M‑0127A AC Current Relay is primarily designed as a recommended addition to the Circulating Current

or Delta VAr1 Paralleling configurations used with LTC Transformers. Its purpose is to monitor the current in

the circulating loop between transformers, and interrupt Motor Power to its monitored transformer, should

the circulating current exceed a predetermined value. The M‑0127A range permits the maximum circulating

current to be set from 5% to 50% of the rated full load current.

Other relays used for this purpose have an impedance exceeding 5.000 Ω which may cause the main CT to

saturate, making the entire circulating current scheme operate poorly. The low impedance of the M‑0127A

relay avoids this problem.

The output should be connected in series with the common lead of the automatic control circuit of the motor

starter relay. When used with the Beckwith Electric M‑0067E control, the M‑0127A output contacts will be

in series with the lead that would otherwise have gone directly to terminal TB1‑8 of the M‑0067E. Polarity

of the M‑0127A input and output can be ignored.

M‑0170A Application

The M‑0170A AC Current Relay is intended to be used in the load current circuit to prevent the tapchanger

from changing taps on excessive load current. Its range permits the current setting from 100% to 200% of

the rated full load current. The relay is connected in the same manner as the M‑0127A.

The M-0127A AC Current Relay guards against excessive circulating current using the circulationg current
