BTS POWER

Field software, built in the field, for HV engineers.

Tools made by working protection & commissioning engineers, not by a software house guessing what site work looks like. Offline-first, standards-faithful, and refined on real site work.

BTS Toolbox

Protection & commissioning field tools — the relay wizardry, trip calculations and lookups an engineer actually reaches for, working entirely offline in the switchroom.

Android 100% offline Licensed per device
  • Relay wizards that look like the relay — VIP300 dials, VIP200 DIP switches, Sepam & Terasaki, faithful to the fascia in your hand.
  • IDMT operating times — IEC & IEEE curves, bidirectional, with CT ratio handling and the multiples commissioning actually uses.
  • LV breaker trip units — Schneider ComPacT/Micrologic and ABB SACE families.
  • CT tools — ratio, polarity checks and clamp-on meter lookups.
  • Site lookups — HV test voltages (IEC 60502-2, IEEE 400.2), cable ampacity, transformer vector groups, bolt torque, TLF selection.

SLD Platform

Single-line diagrams and switching schedules for MV/HV sites. Walk the site with a tablet, lay out the drawing at your desk, print SLDs and staging diagrams for planned works.

Works offline IEC 60617 symbols No install needed
  • Survey on site — capture substations, switchgear and connections on a phone or iPad, no signal required; share the site file when you're done.
  • The diagram is the data — one network model drives the SLD, the asset register and the schedules. Nothing drawn twice.
  • DNO-style switching schedules — isolation and earthing sequences generated from the drawing; save and recall planned works.
  • Print-ready sheets — formal drawing sheets and switching documents straight to PDF.
