  • The Model 1133A brings laboratory performance to the substation, delivering unprecedented revenue accuracy of 0.025% under most conditions.  Compare this to traditional watt-hour meters which are limited to an accuracy of no better that 0.1% in the lab, with increasing errors as conditions depart the ideal.  The Model 1133A can measure harmonics and K-factor, flicker, interruptions, and log data by time interval, or record out-of-limit events with time of occurrence.  You can set limits on any quantity. 

    The Model 1133A measures system (absolute) phase angle, system frequency.  These measurements are made possible with the Model 1133A's internal GPS synchronization.

    A built-in GPS satellite receiver synchronizes your Model 1133A within 1µs of Coordinated Universal Time (UTC).  Other substation equipment, such as digital fault recorders, solid-state relays, remote terminal units, and programmable log controllers, may be synchronized with the standard IRIG-B unmodulated time code output.

    The Model 1205 is available in two versions, the Model 1205B and the Model 1205C.  The Model 1205B has eight status LEDs, an LCD status back-lit display, and a keyboard. The Model 1205C adds a large (20 mm or 0.8 in.) LED time display. Both versions have 32 receiver channels, capable of tracking GNSS satellite systems simultaneously, providing optimum performance.  This accuracy applies to the PTP network timing, the high drive programmable pulse (including IRIG-B) outputs and optional outputs.  The standard holdover oscillator maintains accuracy of 1 ms/day or optionally 10 µs/day when not tracking satellites.  In addition to enhanced performance, Arbiter Systems' new EPS technology includes GNSS anti-spoofing and secure password-protected and encrypted configuration interface providing robust, reliable synchronization to help comply with latest NERC-CIP requirements.

    The Model 1205B/C timing signals are available via the three Ethernet ports, the thirty-two pin terminal block and from the available option slot.  The three 10/100 Ethernet ports (copper standard, fiber optional) provide status, configuration as well as network timing supporting the NTP, SNTP, PTP (Power Profile supported), SNMP, ICMP, TCP, SSH, SSL, HTTP, HTTPS and DHCP protocols.  The thirty-two pin terminal block provides access to the Model 1205B/C standard inputs, outputs and legacy communication ports.  Two inputs, an event timer and a frequency monitor, are included along with six Programmable Pulse outputs, a modulated IRIG-B output, a FET output, relay contacts, two RS-232 ports and a RS-422/485 port (transmit only).  The event timer, 100 ns resolution, accepts an external 5 V CMOS/TTL signal while the frequency monitor accepts a single phase AC voltage input (50/60 Hz, 120 Vac).  The Programmable Pulse high drive outputs (5 Vdc, 125 mA) are user configurable to unmodulated IRIG-B (UTC, Local, C37.118.1) or pulse output (one pulse a second to one pulse a day).  The modulated IRIG-B outputs a 4 Vpp (20 ohms source impedance) signal and supports C37.118.1.  An SPDT (form C) fail-safe relay is also included and is configurable to Out-of-Lock, Fault, Alarm, Stabilized, or Programmable Pulse.  Three legacy serial communications ports (two RS-232 ports and a RS-422/485 port (transmit only) are included for monitoring and status information. Optional outputs include frequency, (5, 10, 1.544 and 2.048 MHz), configurable fiber optic, configurable 24 V, additional programmable pulse and additional modulated IRIG-B outputs.

    The Model 1205B/C accepts one or two power supplies in a redundant configuration and redundant GNSS inputs.  Standard power options include an 85 to 264 Vac/100 to 350 Vdc or 22 to 67 Vdc supplies with secure terminal strip inlets and surge-withstand capability.  The surge-withstand network is designed to meet ANSI/IEEE C37.90-1 and IEC 61000-4 specifications.  Also included is a built-in lightning arrestor and rear panel ground plate to protect against secondary lightning strikes and other antenna coupled surges.
