Remote Meter Sets

Meter movements and calibration potentiometers are available in separate sets in both single and dual scale models with 3- or 4-inch movements. All are available for EX and EXR TCA series meters and are complete with mirror scales identical to the TCA meters. Single scale sets can be mounted on the customer's panel with the potentiometer in series with the meter movement and connected to the TCA-N-EX by a shielded pair cable. Dual scale models are available for use with the TCA-N/N-EXR series meters. A set consists of an appropriate dual meter, two calibration potentiometers and a three position switch for operation of the relays and selection of separate potentiometers for the two scales.

Standard Meter Panels

Standard 19-inch wide panels are available to accommodate Delta's remote meters. The panels are equipped with mounting holes for the specified remote meter as well as holes for the calibration potentiometer and the ON/OFF or Scale Select toggle switch. Please note that remote meters and meter panels are sold as separate items but will be supplied assembled if requested.

Enclosed Meter Panels

The Enclosed Meter Panel has all the features of the Standard Meter Panel plus a rear panel enclosure with connections for each meter circuit, a Power Supply and provision for an Integrating Buffer Amplifier Assembly. The rear panel also provides a hole pattern for an output connector used for connecting automatic logging, remote control or ATS equipment to the meter circuits.

Integrating Buffer Amplifier Assembly

This printed circuit board assembly contains up to four integrating instrumentation amplifiers to be used when metering outputs for automatic logging, remote control or ATS applications. Each amplifier accepts the output of one TCA-EX or TCA-EXR meter, removes the modulation components and raises the level to 10 VDC full scale. The outputs are low impedance so that the panel meters and auxiliary equipment can operate simultaneously. The assembly requires a ±15 VDC supply at 10 mA for the four amplifiers. This assembly is intended for use in the Enclosed Meter Panel but may be incorporated in customer designed circuits.

TCA Power Supply

This modular power supply is for use in the Enclosed Meter Panel and is available for incorporation in customer designed circuits. The TCA-PS2 operates from 120/240 VAC, 50/60 Hz and provides two outputs: a regulated ±15 VDC at 100 mA for the Integrating Buffer Amplifier; and 24 VDC at 0.5A for operating the relays in the EXR series ammeters.

Conductor Bushings

A conductor bushing can be used to increase the voltage rating of a TCA or TCT to approximately 15 kV (RMS crest). The TCA-LS-8 has a 5-inch teflon bushing and an 8-inch conductor for use with a single TCA or TCT current transformer. The TCA-LS-11 has an 8-inch bushing and an 11-inch conductor for use with two TCA or TCT current transformers.

Mounting Brackets

There are three special mounting brackets available for mounting TCA meters on network panels. The TCA-MB-1 is used for mounting one TCT current transformer on a panel. The TCA-MB-2 mounts two TCT current transformers on a panel (the second transformer is typically used for a phase monitor sample). The TCA-MB-3 mounts a single TCA meter unit.
